Helen,
The denitrification process has been a challenge with slow recovery since Florence. Construction debris killed
off the bacteria and the extremely low flows following the storm due to reconstruction inhibited bacteria
regrowth. Routinely in the spring and fall the solids are removed by pumping/ cleaning out the settling tanks
and recip tanks. Due to an increase in occupancy starting the early spring and into the summer months it has
been difficult to accomplish this. Twice we have scheduled the cleaning with the pump truck and manager.
Both times when the pump truck arrived the truck was unable to access the tanks due to cars blocking the
area adjacent to the tanks. Changing the process control timers in an attempt is a slow process. The system
does not react quickly like an activated sludge system. We plan to reschedule the tank cleaning for solid
removal when the flows and occupancy decreases. The manufacturer also recommends cleaning the media.
We will half to close down half the plant to accomplish this. This will involve tankard trucks of hydrogen
peroxide. We will have to locate and hire an outside vendor experienced in this type of work. This will be a
very involved process. There has been a change in management at the facility so efforts to coordinate the tank
cleaning will hopefully improve. We are also changing the ORC for the facility from Stanley Buck to Don
OMara.
Thank You,
Don OMara
