WasteWater

Wastewate is screened

vac-all trucks remove screenings and haul to landfill for final disposal

Aerated grit chambers capture and remove grit

Sewage flows into primary sedimentation tanks that separate about half of the suspended solids from the liquids

step by step- feed modified aeration activated sludge process

6 centrifugal blowers

bubble diffusers

Settled sludge is recycled

Excess biological solids are pumped from the return sludge system as waste activated sludge to the Dissolved Air Flotation Thickeners

Process is a suspended growth biological system starting with 12 reactors

Nitrification process facilities the oxidation of ammonia nitrogen to nitrogen gas.

Lime and sodium hydroxide is added at the head of the nitrification/denitrification reactors to maintain the desired alkanity level that is required for the process to function properly.

Nitrification and denitrification prosess continues with mixed liquor from the odd and even sides.

Nitrification and denitrification effluent flows from the DPSB

Secondary effluent is pumped to the nitrification/denitrification process
