The facility is a top provider of intravenous (IV) solutions in the U.S. and operates as a Standard Industrial Classification (SIC) Code 2834, Class III facility. 1.2 WWTP Facility History The North Cove Facility is located in a geographical region with limited public infrastructure to support operations, resulting in the facility operating a private wastewater treatment facility for proper handling of facility domestic and industrial wastewater. The wastewater treatment facility is a National Pollutant Discharge Elimination System (NPDES) permitted facility, number NC0006564. Baxter Healthcare has operated wastewater treatment operations for the life of the facility. In 2017 the facility completed a significant upgrade, installing new wastewater treatment systems including two new equalization basins, screening, pH neutralization, activated sludge bioreactors, membrane bioreactors (MBR), and ultraviolet (UV) disinfection. These upgrades have resulted in no exceedances of permit limits and over 85 percent of all Discharge Monitoring Report (DMR) parameters being reported below the detection limit (BDL). In 2021, the facility submitted for renewal of the NPDES permit in a timely manner. The final permit renewal was issued on October 17, 2022 and included a change to the temperature requirements for the facility from "monitor and report" to a required maximum temperature and upstream to downstream temperature differential, located in Part I A.(3.) of the permit, titled Schedule of Compliance Temperature Outfall 001 and Instream. 1.3 Schedule of Compliance— Temperature Requirements as stated in the Final NPDES Minor Modification Schedule of Compliance issued August 16, 2023, are as follows: 1. Effective no later than May 1, 2023, the Permittee shall submit to the Division of Water Resources a temperature study analyzing the impacts of each waste stream on the facility's effluent temperature under diverse operating and ambient conditions and characterizing the impacts of the facility's effluent on receiving stream temperature under diverse operating and ambient conditions. 2. Within eight months of completion of the temperature study and no later than December 30, 2023, the Permittee shall submit to the Division, a Corrective Action Plan (CAP) for approval that summarizes the actions to be taken to achieve compliance with 15A NCAC 028 0211(18) and .0219. The time to compliance shall be no longer than two years and six months from the date of submission of the CAP. The CAP shall include, at a minimum, a summary of the options analyzed, a detailed analysis of the Permittee's preferred alternative, including preliminary design engineering and a schedule for procurement of funds and/or approvals, construction, and necessary operation changes. The CAP shall propose a schedule for completion of critical milestones until compliance is achieved. The Division will provide comments and direction, if deemed necessary, within ninety(90) days of CAP submittal. If no such direction is provided, the CAP shall be considered approved. 1 Corrective Action Plan Baxter Healthcare Corporation—NC0006564 3. Effective no later than September 1, 2024, the Permittee shall submit a progress report to the Division summarizing the actions taken in accordance with CAP and schedule, including procurements, construction, installation, or other measures. 4. Effective no later than September 1, 2025, the Permittee shall submit a progress report to the Division summarizing the actions taken in accordance with CAP and schedule, including procurements, construction, installation, or other measures. 5. Effective no later than March 1, 2026, the Permittee shall achieve compliance with temperature limits specified in condition A. (1.). In addition to steps 1 through 5, upon approval of the CAP by the Division, the milestones outlined in the CAP become an enforceable part of the permit. Any modification to the schedule for these milestones must be requested to the Division at least ninety(90) days before scheduled deadline. Modifications more than four(4) months or more than one 4-month modification request to the schedule will be subject to public notice. To satisfy these requirements Baxter Healthcare contracted assessment and analysis services from Jacobs Engineering, ERM, and PCl/Salas O'Brien. Jacobs Engineering performed the initial Temperature Study as required in the first condition, submitted by Baxter on May 1, 2023. In June 2023 Baxter Healthcare submitted for an extension of the Corrective Action Plan submittal deadline from September 1st, 2023, to December 30th, 2023, as a minor modification. Approval for this modification was granted on August 16, 2023. The submittal of Sections 2-4 of this document satisfies the second condition of the Schedule of Compliance. Baxter Healthcare submitted the Corrective Action Plan on December 29, 2023, as required by the second condition of the Schedule of Compliance. NCDEQ issued the CAP Response on March 25,2024, stating that the CAP was not approved, recommending further discussion of alternatives. 1.4 Previous CAP Submittal The previous CAP provided an assessment of eight cooling options, with none demonstrating satisfactory compliance with Class B Coldwater trout temperature standards for the receiving section of the North Fork Catawba River without support from a 316(a) variance. The CAP outlined a preferred and feasible option which included a combination of a raw water heat exchanger, sampling point relocation, and a 316(a) thermal variance. 1.5 Components of the Revised CAP Submission The NCDEQ Response cited significant reservations with a 316(a) proposal. In order to resolve these reservations Baxter Healthcare proposed submittal of a revised CAP exploring an alternative including outfall relocation to a receiving stream with Class C temperature standards. This option was previously considered not a viable alternative as access commitments could not be secured within the timeline provided for the CAP submittal. 2 Corrective Action Plan Baxter Healthcare Corporation-NC0006564 This revised Corrective Action Plan submission satisfies condition 3 of the Schedule of Compliance. Assessments performed by consulting groups will be summarized within the text and included as attachments where relevant. 3 Corrective Action Plan Baxter Healthcare Corporation—NC0006564 SECTION 2: SUMMARY OF OPTIONS ANALYZED (For Condition 2. in the Schedule of Compliance) 2.1 Outfall Relocation Prior to 1994 the treatment facility at Baxter discharged through a largely subsurface forcemain to a location south of Armstrong Creek where the classification of the North Fork changes from Class B Cold Water Trout to Class C. At this location, the temperature standards change to a no greater than 29 degrees C and an induced temperature change of no more than 2.8 degrees C from ambient conditions. The facility has made significant effort to explore the viability of relocating to this historic discharge location, with the following conclusions: 1. The remnants of the existing forcemain are not of sufficient condition to be restored/rehabilitated. 2. Documentation for legal easements/access rights was not available, and this option will require Baxter to obtain new access rights prior to installing a new pipeline. 3. New construction pathways through the railroad corridor on the eastern side of the North Fork and along State Highway 221 on the western side of the North Fork have been preliminarily assessed. The facility has had preliminary conversations with the railroad owner (CSX), additional private property owners, and the NC Department of Transportation regarding the viability of a new construction low-pressure forcemain. Specific alignments that have been explored are (with colors corresponding to Figure 1.): a.

This alignment would also require additional easements along American Thread Road and down to the discharge point via Good Road. • All of the road only alignments required multiple easements with different property owners. Baxter was able to get a written commitment from NCDOT that if easements could be gained from other property owners along a given alignment, NCDOT would grant a similar easement to complete a pathway for the proposed outfall pipeline. (Figure 2.) • All reasonable identified alignments of the discharge pipeline to the relocated outfall would need to pass through property, via easement, owned by Coats (aka American Thread).

This would be constructed using industry standard forcemain construction techniques and materials primarily consisting of butt fusion of HDPE pipe. Preliminary design for this indicates that 12-inch pipe would provide sufficient capacity for effluent discharge rate. Material specifications have been assessed in accordance with NCDOT requirements and best engineering design practices for forcemain construction. Effluent would enter the forcemain via a lift station located on the wastewater treatment plant property, with redundant pumping systems and overflow control into existing storage ponds. Piping would be installed via a combination of trenching and directional bore, in compliance with NCDOT requirements and best construction practices. Preliminary materials quantities have been calculated, initial field reconnaissance for utility considerations, private access roads/drives, and geographic restrictions has been performed and taken into consideration in route selection. 7 Corrective Action Plan Baxter Healthcare Corporation-NC0006564 2.3 Wastewater Cooling The relocated outfall proposal would discharge into Class C waters with a temperature standard of 29 degrees C and a temperature rise standard of 2.8 degrees C. As a result, Baxter requested that PCI, a Salas O'Brien company (PCI), revisit the wastewater cooling study to meet the updated water temperature standards for Class C waters, and to include two additional options, a mechanical cooling via cooling tower to the Class C compliance requirements and cooling of effluent via inclusion of pumped groundwater. 1. Cooling Effluent with Groundwater—This option proposes cooling the combined wastewater effluent stream using groundwater pumped from either of two new wells located on the site, utilizing an inline mixer. Rate of well water addition would be adjusted based on temperature after mixing. 2. Mechanical Cooling via Cooling Tower—The WWTP effluent would be passed through a cooling tower and, using evaporative cooling, reduce the discharge temperature to the required 29 degrees C. The assessments for both options are included in Attachment 1 — Wastewater Temperature Reduction Technology Assessment: Class C Options— Salas O'Brien 2.4 Sampling Point Relocation The current discharge permit for Baxter Healthcare requires temperature monitoring at three points, three times a week: • Upstream at least 100 feet upstream from the outfall location • Effluent temperature at discharge • Downstream at NCSR 1552 With the proposed relocation of the outfall Baxter proposes to modify these to the following: • Upstream - monitored at least 100 feet upstream from the new outfall location, with consideration for ease of access. • Effluent— monitored after mechanical cooling and prior to entry into the forcemain. • Downstream—demonstrated by a modeled mixing zone meeting the maximum 2.8 degree C temperature differential. A modeled mixing zone would provide a practical way to demonstrate compliance that is protective of North Fork Catawba River's temperature standards and remove the need for an alternate downstream sampling point that would require additional property owner access agreements and practical challenges due to ground considerations. 2.5 Biological Reactivation Review During initial discussion of a pipeline relocation alternative, NCDEQ stated that other regulatory agencies had previously stated concern about potential reactivation of bacterial population within a discharge pipeline. Baxter evaluated the potential for reactivation of biological contaminants based on multiple factors specific to the North Cove facility. As the facility uses a membrane bioreactor filtration system, capable of removing contaminants larger than 0.01 micrometers, the bioreactor will remove most, 8 Corrective Action Plan Baxter Healthcare Corporation—NC0006564 if not all, of the bacteria and viruses. This is further supported by 5-day BOD analytical test results. The estimated residence time within the pipeline is approximately 2.5 hours at full pipe flow. Literature previously shared with NCDEQ via presentation on this system is included as Attachment 2. 2.6 Analysis Summary During assessment of the above Baxter determined that relocation to a Class C receiving stream with supplemental cooling presented a viable alternative to the previously submitted CAP and initiated pursuit of the necessary access agreements. This process was initiated in the first quarter of this year. Corrective Action Plan Baxter Healthcare Corporation—NC0006564 SECTION 3: PREFERRED ALTERNATIVE AND PROGRESS (For Condition 2. in the Schedule of Compliance) 3.1 Effluent Cooling Tower Of the options evaluated and in combination with relocating the outfall to Class C waters, the effluent cooling tower was found to be the most sustainable and effective means by which Baxter is able to consistently meet the required discharge temperature. This option carries the following advantages over the groundwater cooling option: 1. Proven technology 2. Lower power requirements 3. Lower environmental impacts (no substantial additional power use, no groundwater requirements) 4. Construction needs limited to available space currently on the Baxter plant site 5. Can be used as needed (based on ambient conditions) without loss of effectiveness A second cooling tower, with associated infrastructure, pumps, etc., will be constructed for redundancy and continued permit compliance should the need arise to shut down the cooling tower that is in use. 3.2 Outfall Relocation Based on multiple analyses and extensive research and conceptual design, including costs, access, constructability, number of required easements and the ability to acquire those easements, and schedule, Baxter had deemed alignment 2. noted in Section 2.2 (State Highway 221 to the Oak Valley Property to American Thread Road and then Good Road) as the most sensible pathway due the requirement of a limited number of non-NCDOT easements. In pursuit of this alignment Baxter reached out to the current property owners, Oak Valley and Coats, regarding granting of easements. Baxter contacted Coats early in the process via an existing professional connection and received positive initial response. This was the understanding when Baxter provided a proposed access agreement, receiving response from Coats indicating that upon further consideration they were unable to facilitate the request, citing a number of concerns that did not include the payment for the easement. However, Baxter has continued further dialogue with Coats in an effort to address those concerns. During the process of evaluating the various routings of the discharge pipeline, it became clear that in order to complete this discharge relocation an easement, or easements, would need to be granted for the Coats property regardless of the route taken. Coats currently owns property on both the north and south sides of American Thread Road as well as all properties surrounding Good Road, the only viable access for Baxter's pre-1994 discharge point. This effectively blocks any and all access to the planned discharge point regardless of the pipeline alignment selected.

However,following that return, the Oak Valley property owners informed Baxter that they would not be willing to grant an easement across the property for reasons other than the cost of the easement. Baxter attempted to re-engage the Oak Valley property owners for further discussions, but those attempts were declined. Baxter remains committed to finding a reasonable route for the proposed discharge pipeline and will revisit the previously discussed alternatives to the Oak Valley property in addition to formulating other alignments and/or solutions while pursuing a positive result with Coats. However, it should be noted that these continuing efforts will jeopardize future milestones within the current Schedule of Compliance. 3.3 Summary Baxter Healthcare has engaged a significant amount of internal and external subject matter experts to assess the viability of relocation from Class B coldwater trout waters to Class C waters, enabling supplemental cooling of the effluent to meet compliance requirements without variance. The preferred alternative proposed in this Revised CAP and Progress Report would consist of mechanically cooling effluent to meet Class C temperature maximums prior to entering a forcemain and demonstrating a sufficient mixing zone at discharge suitable to aquatic life within the section of the North Fork receiving discharge. Preliminary design of all infrastructure components has been completed to the extent possible without final route determination. 11 Corrective Action Plan Baxter Healthcare Corporation—NC0006564 Baxter proposes to continue pursuit of a viable pathway to Class C waters and will provide NCDEQ with an update on this effort within 30 days of securing all necessary access agreements or by the next milestone in the schedule of compliance, September 1, 2025. 12 Corrective Action Plan Baxter Healthcare Corporation-NC0006564 SECTION 4: SCHEDULE (For Condition 2. in the Schedule of Compliance) The proposed schedule of compliance is dependent upon securing the necessary access agreements, and is therefore provided in time from securing agreement: Q1 Year 1 (first full year after securing necessary access agreements): Submit a revised CAP with the secured alignment Q2 Year 1: Internal Project Charter Issuance Scope of Work or Design Q3 Year 1: Design Cooling Tower System Coordination of Permits for River Crossings and Land Disturbance (as applicable) Q4 Year 1: Bid Construction Procurement Process on Components Qi-Year 2: Receive Capital Review Bids and Component Procurement Award Construction Q2 Year 2: Begin Prelim.

The proposed discharge point is approximately 3 miles downstream of the site. At this location, the maximum discharge temperature is 29°C (84.2°F). This report details options for cooling the WWTP effluent to 29°C (84.2°F) prior to discharge to the Catawba River at the end of the pipe. Options for cooling the WWTP effluent include adding ground water pumped from the aquifer below the facility, cooling the effluent with evaporation and/or refrigeration, and/or implementing heat recovery options within the facility. BACKGROUND The Baxter North Cove facility (Figure 1) operates a National Pollutant Discharge Elimination System (NPDES) permitted wastewater treatment plant (WWTP) with direct discharge into the North Fork of the Catawba River. The current WWTP has operated continuously since 2017, following completion and startup of a WWTP utilizing best available wastewater treatment technologies. The replacement WWTP was permitted under the existing WWTP permit with discharge conditions largely unchanged. This permit did not include a temperature compliance requirement. This condition was changed in 2022 with issuance of the permit renewal from North Carolina Department of Environmental Quality (NCDEQ). These conditions for temperature require the facility to not raise the river temperature by 0.5°C (0.9 °F) temperature between a point upstream of the plant and a point downstream of the plant. The NCDEQ has specified a maximum site outfall temperature of 20 °C (68 °F). If the upstream (background) monitoring point exceeds 20 °C (68 °F) the facility will not be out of compliance if it does not cause any increase in background temperature. Baxter Healthcare Corporation (Baxter) reached an agreement with the NCDEQ in April of 2022 requiring Baxter to assess thermal effects on the North Fork of the Catawba River and within their facility, as well as proposing operational changes or capital projects to ensure compliance with the temperature requirements within the new permit. Baxter is engaged in an ongoing assessment of thermal effects on the North Fork of the Catawba River. Review of Catawba River discharge requirements found that the river's classification changed approximately 3 miles downstream from the plant. In that downstream section of the river, the requirement is to normally discharge at less than 29°C (84.2°F). The State of North Carolina also requires that the discharge cannot result in a 2.8°C (5.0°F) or greater impact between upstream and downstream monitoring points. salasobrien.com 4 a A previous study evaluated the capital and operating expenses to cool the site's effluent temperature to 20°C (68°F) through a variety of options. Due to the 20°C effluent temperature, many of them required refrigeration that is impractical. Baxter Healthcare identified an opportunity to discharge warmer water into the Catawba River further downstream of the plant. This study supports efforts to design a viable process to keep WWTP effluent temperature below 29°C and satisfy wastewater discharges into the river. PROJECT DESCRIPTION The scope of this project is to propose and access potential processes to reduce the plant's WWTP outfall temperature to 29°C at the end of the pipeline. Options evaluated in this project will become a component of the Corrective Action Plan (CAP) for collaborative assessment with NCDEQ on the best combination of operational changes, technological controls, and permit condition modifications to ensure the North Cove WWTP remains compliant with all of the terms of its NPDES permit. The results of this assessment will be incorporated into the environmental and ecological assessments to present a CAP that proposes the best comprehensive method for meeting the regulatory needs of the facility. The entire study is based on the North Cove Water Balance provided by Baxter (Figure 2). Well water enters the plant (shown in blue) on the left side of the figure. The wastewater from the plant (shown in red) drains into one of 5 main sumps (Orange). Two primary drain lines collect water from manufacturing processes and domestic usages and are pumped to the WWTP through the Pump House located between the main plant and WWTP. Four spray ponds cool water from the sterilization lines. The ponds are pumped through a separate line to the WWTP. As the cooling pond water is heated (essentially sterilized water) and biologically inactive, it typically bypasses the WWTP and combines with the WWTP outflow. All water discharge passes through a final UV treatment before flowing into a tributary of the Catawba River. OBJECTIVE The objective of this project is to evaluate process options to limit the WWTP effluent to a maximum temperature of 29°C (84.2°F) at the end of the pipeline. Baxter specifically requested that Salas O'Brien evaluate how much groundwater was required to cool the effluent stream and designing a process using best available technologies to cool the WWTP effluent stream to 29°C prior to pumping it to the downstream discharge location. Full analysis of these two options is included in this report. ASSUMPTIONS The following assumptions were used in the analysis: 1. The analysis is based on average and maximum temperatures at each sump as shown in Figure 2. 2. The desired discharge temperature is a maximum of 29°C (84.2°F). 3. Negligible cooling will occur in the line from the site to the downstream discharge location. salasobrien.com 5 a 4. For equipment design, maximum stream temperatures will be used. 5. For this analysis, it is assumed that no heat is gained or lost in the wastewater treatment facility. 6. It is assumed the wastewater temperature from the Boiler Room and 5A sumps is consistent year-round. 7. A cooling tower can reduce the temperature of the water passing through it to within 7°F of the Outside Air Wet Bulb Temperature. 8. The design wet bulb temperature for the North Cove Site is 75.3°F. This is based on available design information for Ashville, NC, and SPX Cooling Technologies.

ANALYSIS Option 1 : Cooling the WWTP Effluent with Groundwater Baxter requested that Salas O'Brien evaluate cooling the WWTP effluent by adding groundwater sourced from wells on the Baxter site. The WWTP effluent and the groundwater would be mixed at the Baxter site and then pumped through a pipeline to the downstream discharge point three miles from the site. Calculations will be made concerning the amount of water needed to cool the WWTP effluent. salasobrien.com 8 a Figure 3: WWTP Effluent Cooling with Groundwater ww,..,i,,,,„„ > f I 1 ,:oole,43 Ponnt 0.Alow Abaft .4--. .„:3 ,.....,., .. 1 // ..

Local meteorological conditions will be evaluated to identify and estimate cost to implement that technology.

A low-pressure drop inline mixer quickly mixes the two streams together and the temperature is measured prior pumping the site's effluent to its discharge point. The rate of well water addition is adjusted based on the temperature after mixing. Salas O'Brien was asked to evaluate the amount of ground water needed for this option. Figure 5 shows the temperature of the wastewater treatment plant effluent including the cooling ponds. Hourly temperature data was obtained from the Grandfather, NC weather station and averaged over each month. Based on the Phase 1 study, the cooling pond outflow temperature is approximately 20°F warmer than the wet bulb temperature and the WWTP plant effluent is fixed at 89°F based on plant data recorded in May 2023. Using flows in Figure 2, the calculation spreadsheet developed for the Phase 1 study was setup to calculate the ground water flow requirements for both normal groundwater temperature (65°F) and for an elevated temperature of 68°F. Analysis of the WWTP effluent temperature data captured in May 2023 found it fluctuated from 79.8 to 89.0°F. Likewise, the cooling pond outflow varied between 77.0 and 90.3°F. To cool the site's effluent to 29°C (84.2°F) at the highest temperature from both effluents would require 202 gpm (291,000 gpd). At average temperatures, 170 gpm is needed. Higher groundwater flow rates are required when the cooling pond temperature fluctuates based on wet bulb temperature. Figure 5 shows monthly estimated waste wastewater effluent temperature over a day. Ground water addition is required in all months except January, February, March, and December. The amount of groundwater needed to cool to 29°C is graphed in Figure 6. Continuous ground water addition is required in May, June, July, August, and September. Groundwater usage is predicted to exceed 250 gpm during the evenings of July and August. Table 2 summarizes the estimated energy and cost for blending groundwater to the WWTP and cooling pond effluent stream. It is recommended that the groundwater well pumps be able to provide 275 to 300 gpm of groundwater to adequately cool the site's effluent temperature. An inline static mixer is recommended to quickly blend the cool groundwater with the WWTP and cooling water streams; the mixer should be capable of handling 1000 gpm. Finally, a lift station is required. Its size will depend on the hold time Baxter deems necessary. salasobrien.com 10 a Figure 5: Estimated Temperature of Combined WWTP and Cooling Pond Effluent 4' W ML° 90 --+r-- rii 44 3 w 85 - -- - 19"L;61.7`F-Ma.murr Permitted Site Outflow temp.

First, the cooling tower vaporizes a small fraction of water to lower overall water temperature. Finally, a chiller system utilizes a refrigeration system to further cool the streams. A cooling tower is capable of lowering water temperature to within 5 to 7°F of the wet-bulb temperature. The maximum wet bulb temperature determines the highest temperature of the water leaving the tower. To determine the design maximum wet bulb temperature, meteorological records at Christmas Mountain, NC were retrieved, and design guidelines published by ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers)for Asheville, NC were reviewed. The ASHRAE recommends 74.3°F as the design wet bulb temperature (Table 4). Finally, SPX/ Marley Cooling Towers recommends using 75.3°F (24.1°C) as the design temperature. Based on these guidelines, a cooling tower with a 7°F approach can cool water to 82.3°F (27.9°C), below the maximum discharge temperature for the section of river Baxter proposes to discharge into. As a result, a cooling tower is sufficient for cooling the site's effluent to 29°C. Figure 7 shows the cooling water temperature based on the monthly ASHRAE wet bulb data.

Calculations determined that the maximum temperature combining the cooling ponds' effluent and the WWTP effluent was 90.5°F. Based on an average site flow of 635 gpm, a cooling tower capable of cooling 2.15 MBTU/h or 143 tons was necessary. It is recommended to specify a cooling tower capable of at least 150 tons. For redundancy, two cooling towers are also recommended. Figure 8: Hourly Cooling Water Effluent Temperature by Month 90 LL } E r.

The system consists of a covered basin, pumps to lift water to the cooling tower, two cooling towers (one as backup), and a second covered basin to hold water prior to being discharged to the effluent pipeline. Specifically, the covered basin has three or more sump pumps. The pumps are rated for a head of 35-40 ft, depending on the sump's depth. For a sump with three pumps (two operating pumps, one standby), each pump requires approximately 5 HP. Pump operation could be tiered to sump level. The pumps lift water to the water distribution system of an d cooling tower. Water passes through the cooling tower i n a single pass a d flows into the final basin. The design of the effluent pipeline is outside the scope of this work.

The previous study recommended collecting hot water from Sump 5A and the Boiler Room Sump, storing it in an insulated tank and then pumping the hot water to warm the treated water for WFI generation and steam production. Calculations indicate heat recovery would eliminate the need for either groundwater or evaporative cooling. It would require investment in an insulated holding tank, pumps, and heat exchangers. Concern has been expressed about the potential for contaminating water fed to the WFI generation system. For this project, only a preliminary assessment was made, and no further development work was undertaken. salasobrien.com 15 Corrective Action Plan Baxter Healthcare Corporation—NC0006564 ATTACHMENT 2: Biological Reactivation Review Presentation - Baxter Healthcare Baxter Wastewater Treatment Facility State of the art WWT facility was constructed and brought online in 2017 • Membrane Bioreactor System which has the capability to filter water containments down to the virus size. • The system is design with redundancy in the treatment processes Baxter WWT Process Flow ()STERILIZER WATER > H AREA TO/ I �P _ t1u0N % '...
