Fixed Activated Sludge Treatment System
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... (read more)

Aerators Enhance Aerobic Digester Process
In 2003, Eden WWTP staff became aware of floating brush rotor aerators as a potential approach to providing oxygen transfer and mixing in the aerobic digester. AERATORS ENHANCE AEROBIC DIGESTION PROCESS. After installing four 20-hp aerators, the city of Eden, N.C., happy with performance, results
PTMD Scrubber Improves Odor Control at Vancouver Island Wastewater Treatment Plant
The French Creek Pollution Control Centre treats wastewater from the City of Parksville and the Town of Qualicum Beach on Vancouver Island in British Columbia. Originally, the plant used the extended aeration process with aerobic sludge digestion for wastewater treatment. From 1995 to 1997
Hoechst Celanese Corporation, Bishop, TX
Aerobic biological sludge blowdown from the clarifier in the wastewater treatment system previously had been discharged to solar ponds.
Application of pre-acidification
tank reactor (CSTR) followed by anaerobic/aerobic series treatment. COD and TSS reductions of 34% and 80% respectively, in the acidogenic stage, resulted in effluent that responded well to the anaerobic/aerobic series treatment. The system produced final effluent in which COD and TSS had been reduced
