FAST® Process Treatment SystemSource: Smith & Loveless, Inc.
The patented FAST® Process stands for "Fixed Activated Sludge Treatment", a fixed-film, aerobic treatment system designed for tackling variable load and flow conditions. Proven in thousands of installations worldwide, FAST® consists of tankage packed with completely submerged media. The FAST® media creates a high surface area-to-volume ratio, which combined with internal settling zones, maintains constant bacterial growth during low-flow and peak usage. This results in stable operation on a daily basis.
