Sewer Pretreatment Systems With Diagram

[Diagram Details Below]

  1. Stainless Steel Inlet Compartment – The water is pumped into the system through a non-clogging diffuser pipe to distribute the flow. The inlet chamber is designed to reduce suspended solids, dissipate energy and begin separation.
  2. Sump Pump – Water is pumped into the system via an air diaphragm sump pump.
  3. Inclined Plates – Inclined plates above the sludge chamber catch suspended particles as the water stream moves into the separation chamber.
  4. Separation Chamber – After the water travels up the inclined plates, it flows into the stainless steel separation chamber containing the coalescing media.
  5. Coalescing Media Packs – The high efficient coalescing pack in the separation chamber further slow the water velocity so oil drops out of suspension and clings to the media. This media will remove 99% of free oil droplets 20 microns or larger.
  6. Oil Skimmer – The oil that has dropped out of suspension is then skimmed off the top of the separation chamber and into a tank for easy removal.
  7. Baffles – An underflow weir will prevent re-suspension of solids while an oil retention weir will keep the oil in the separation compartment.
  8. Ozone Generator – The water is injected with ozone to kill odor-causing bacteria.
  9. Clean Water Chamber – The third stage is a clean water chamber where the clean water will flow out for reuse to the drain.
  10. Float Control System – SPT Series Systems come with optional control systems for simple, automatic operation.
