Curious about a Pro Flo Wastewater Treatment System?
In practice, they are similar to large municipality sewage treatment plants. They use an extended aeration activated sludge process. Aeration depends primarily on introducing air to the wastewater; this promotes the growth of microorganisms that break down the organic material found in regular household sewage.
Raw, unsettled waste/water from your home enters into the pretreatment tank. Inside the pretreatment tank, the solids separate from the liquid and the liquid flows into the aeration chamber. Air is introduced into the aeration chamber by passing from the aerator motor through the diffuser bar and into the system. This air promotes the growth of microorganisms. It is these organisms (bacteria) that break down the organic material. As the wastewater leaves the aeration chamber, it enters the clarifier. No mixing occurs inside the clarifier, but inside, any “leftover” solids (or sludge) separate from the liquid and settle to the bottom of the clarifier. Sludge contains dissolved oxygen and the bacteria it contains are activated by the oxygen. This activated sludge is returned to the aeration chamber where it is mixed and digested again. The sludge mixes with the incoming wastewater and this mixture of returned sludge, wastewater, and dissolved oxygen is referred to as mixed liquor. The mixed liquor flows back into the clarifier, the solids separate and return once again to the aeration chamber. This never-ending cycle produces a clear, odorless, high quality effluent that is ready to be released to the environment.
