The EnviroServer
A basic summary of the system:


  • First Stage:
    (Primary Clarification) Solids/sludge settle into the first chamber.

  • Second Stage:
    (Biological Organic Removal) Wastewater is aerated in the second chamber.

  • Third Stage:
    (Nitrification) The third chamber, with the treated wastewater, is aerated also. Using oxygen in the wastewater, microorganisms nitrify the ammonia.

  • Fourth Stage:
    (Clarification) The wastewater, which has an increase in nitrates, has continued to the fourth chamber. The solids settle.

  • Fifth Stage:
    (Nitrate Removal) The wastewater is returned to the first chamber.

  • Sixth Stage:
    (Solids Removal/Destruction) Recirculated water carries nutrients back to the first chamber. Sludge is pumped into the Thermal Processor, filtered, and water flows back into the first chamber.

  • Seventh Stage:
    (Disinfection) The water is disinfected as it exits the system through the disinfection unit.
