LAMBERTVILLE REGIONAL POLLUTION CONTROL PROCESS KEY

  1. Lambertville, Stockton and Bucks County Flows go through an influent flow meter.
  2. The sewage goes through a screen that removes rags and debris from the flow.
  3. Next, grit is removed and stored in a dumpster for removal and disposal at a landfill with material from step 2.
  4. After these processes, the sewage goes to a splitter box that divides the flow.
  5. Flow is sent to the primary clarifiers for settling.
  6. 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.
  7. The flow is then sent to the secondary clarifiers for further settling.
  8. After treatment in the secondary clarifiers, the liquid flows to the chlorine tanks for disinfection.
  9. After this, the liquid is de chlorinated, i.e. any leftover chlorine is removed.
  10. The effluent is then discharged into the Delaware River.
  11. 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.
  12. Sludge produced in steps 5 and 7 by settling of the sewage, is pumped to the sludge pumping station.
  13. The station sends the primary and secondary sludge to the primary and secondary holding tanks (Biosolids Tanks) for storage.
  14. From the holding tanks, sludge gets pumped to the belt filter press where it is dewatered.
  15. 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.
