NPDES NC0035904 11 12 yr/mo/day 04/04/19 117 Inspection Type 18 (cont.) 1 Section D: Summary of Finding/Comments (Attach additional sheets of narrative and checklists as necessary) Facility was having a problem with low ph's on the effluent and aereation basin. The clarifier was completely brown/turbid with no floc separation. The aeration basin had high dissolved oxygen (6-7mg/1) & very' low ammonia nitrogen values. The aereation basin is a retrofit from a previous trickle filter with a detention time of three days. It has three floating aereators and the operator was operating all three because of the mixed liquor solids (4000mg/1) were settling in the basin when turned off. The effluent was in noncompliance with total suspended solids on the day of technical assistance. RECOMMENDATION: 1) immediately lower dissolved oxygen (d.o.) to less than 1 mg/1 to cause the activated sludge to denitrify (this will stop nitrification and will cause the ph to rise) 2) order timers for the aereators so they can be programed to operate at various times so overaereation will not occur.(d.o. should range from 1-2 mg/1) 3) Increase sludge wasting until the effluent ammonia nitrogen increases(since ammonia removal is not required by the permit). This lower MLSS will be where you will want to operate the aeration basin mixed liquor suspended solids in the future. • Follow-up:This facility had the recommended timers ordered dnd installed by the end of the month, the other recommendations were followed and compliance with the permit was resumed in the month of May.
