ABOUT FAST 

 
The FAST® (Fixed Activated Sludge Treatment) system uses naturally occurring bacteria (biomass) to treat 
sewage for dispersal into the environment. This continuous process provides the biomass with food (waste) 
and air in a suitable environment. Dead bacteria and non-biodegradable waste settle and accumulate in the 
bottom of the tank for periodic removal.  
The FAST assembly consists of two components: the treatment module and blower. The blower provides air to 
the system via the air supply pipe. The air supply pipe and draft tube create an airlift, which mixes oxygen and 
waste throughout the media inside the tank. Bacteria, supported by air from the airlift, grows on the media 
and digests the waste. Finally, a vent pipe expels vapors created by the process. 

 

 

 

 

 

Always secure all access covers to prevent unauthorized people from entering the tank. Only 

qualified service personnel should open access ports and/or covers.  

 

Infectious organisms also exist in a septic tank. So if any contact with wastewater occurs, 

immediately wash and disinfect all exposed areas and contact personal physician. Failure to 

do so could result in severe sickness or death.  

 

DO NOT use an open flame or cause a spark near a septic tank’s access points. Gases 

emanating from septic tanks can explode if ignited or deadly if inhaled.
