An aerobic septic system is a closed system that takes in raw sewage from a residence or a business.  This sewage arrives first in a chamber where solids and liquids will be allowed to separate.  Solids will settle on the bottom of this chamber while the left-over liquid, called effluent, will flow into a second chamber, the aeration chamber. Air is pumped into this chamber by an aerator through a diffuser which produces exponential bacterial growth.  The bacteria are responsible for the rapid decomposition of organic matter in the aeration chamber.  In the Proflo systems, a third chamber called a clarifier is utilized that allows residual solids to again settle at the bottom of this “quiet chamber”. The residual solids, AKA sludge moves back into the aeration chamber to be mixed with incoming effluent, all of which will continue to be digested by bacteria until it will again move into the clarifier.  This is a continual process the result of which is an eco-friendly effluent in a relatively short amount of time.  Once thoroughly treated, the now eco-friendly effluent moves into the pump tank.  As the effluent reaches a certain level in the pump tank, it is pumped out to be dispersed into the environment. For surface level disbursement (sprinklers), the effluent is chlorinated along the way to ensure disinfection before it reaches ground surface.
