  1. Lynn Waste Water Treatment Plant

  2. Preliminary Treatment Process objects are remove to protect the equipment in the plant from physical damage.

  3. Barscreen Drawing & Animation

  4. Barscreen Room Barscreens

  5. Primary Treatment Process removes Settleable and floatable materials from the wastewater

  6. Screening

  7. Primary Clarifiers : Grease and other floatable material is skimmed from the surface and collected

  8. Secondary Treatment Process Pollutants dissolved that would not settle in the primary clarifiers flow on in the wastewater to the Secondary treatment process

  9. The secondary treatment • Oxygenation Tanks • Pure Oxygen Generating Plant • Liquid Oxygen Storage Tanks • Secondary Clarifiers • Return Sludge Pumping Station and Splitter Box • Sludge Thickeners and Pumping Station • Sludge Dewatering Building Addition and modifications to the existing Service Water Pumping Station

  10. The oxygenation system

  11. The primary effluent enters the head end of the tanks where it mixes with return activated sludge which consists of microorganisms "activated" by the organic matter and oxygen. This combination of primary effluent and return sludge forms a mixture known as "Mixed Liquor".

  12. PSA Compressors PSA Molecular Sieve The Pure Oxygen Generation System incorporates a pressure swing adsorption (PSA) system oxygen generating system

  13. The activated sludge process is an aerobic, suspended growth, biological treatment method. It employs the metabolic reactions of microorganisms to produce a high quality effluent by oxidation and conversion of organics to carbon dioxide, water and biosolids (sludge).

  14. Since the population of microorganisms is growing some microorganisms in the return activated sludge are removed from the system. This solids waste stream is called waste activated sludge  ( WAS ) and flows to the secondary gravity thickener for Solids Processing.

  15. Secondary Clarifiers

  16. The cleaned wastewater flows over the weir of the secondary clarifier and on to the disinfection (chlorination) process.

  17. Solids Residual Handling Dewatering ( the removal of water from sludge )

  18. INCINERATION

  19. - burn the sludge at approximately 1400 degrees Fahrenheit The remaining ash is hauled to the off-site landfill for disposal.
