LAMBERTVILLE REGIONAL POLLUTION CONTROL PROCESS KEY
- Lambertville, Stockton and Bucks County Flows go through an influent flow meter.
- The sewage goes through a screen that removes rags and debris from the flow.
- Next, grit is removed and stored in a dumpster for removal and disposal at a landfill with material from step 2.
- After these processes, the sewage goes to a splitter box that divides the flow.
- Flow is sent to the primary clarifiers for settling.
- After the flow has settled it is processed by the rotating biological contactors (RBC). Part of the flow goes through RBC #1 and part to RBC#2. Each contains four RBCs.
- The flow is then sent to the secondary clarifiers for further settling.
- After treatment in the secondary clarifiers, the liquid flows to the chlorine tanks for disinfection.
- After this, the liquid is de chlorinated, i.e. any leftover chlorine is removed.
- The effluent is then discharged into the Delaware River.
- The effluent can then be reused in accordance with the plant’s permit, such as wash down at the plant, cleaning sewer lines, and heating and cooling of our office using a geothermal system.
- Sludge produced in steps 5 and 7 by settling of the sewage, is pumped to the sludge pumping station.
- The station sends the primary and secondary sludge to the primary and secondary holding tanks (Biosolids Tanks) for storage.
- From the holding tanks, sludge gets pumped to the belt filter press where it is dewatered.
- The dewatered sludge cake is then loaded in a dumpster. When full, the dumpster is hauled to a processing facility for incineration. The residual water flows to the submersible pit where it is pumped through the plant for treatment.
