Living colonies, made up of millions of bacteria, called a “biomass”, occur in all sewage wastewater. In a standard septic tank the biomass remains free floating (or unfixed) throughout the tank liquid. Suspended throughout the wastewater, these bacteria spill out, untreated and unfiltered, clogging and damaging drain fields, adjacent site property and ground water.
Fixed Activated Sewage Treatment = FAST®
FAST® systems begin processing effluent by creating a strong air-lift inside the sewage treatment module. The air-lift pump and draft pipe continuously mix fresh air with incoming wastewater and cascade it vigorously across the FAST® Honeycomb Media – the heart of the FAST process.
