Demonstration System Tour: Property FAS1
Technologies:Fixed Activated Sludge System with Ultra Violet Light and Shallow Narrow Drainfield For more information on fixed activated sludge treatment systems: This technology is a proprietary device under the trade name MicroFAST® Wastewater Treatment System, manufactured by Biomicrobics Incorporated. For more information on this treatment technology, see the vendor website at www.biomicrobics.com. Year Installed: Site Description:
System Treatment Train: Wastewater exits the home through a gravity-flow building sewer
(A) and enters a two-compartment tank (B). A blower (C) supplies
air to the advanced treatment portion of the tank, in the
second compartment. The first compartment is a septic/trash
compartment
where solids settle. The second compartment houses the fixed
activated sludge unit. Wastewater moves through the unit
by gravity displacement, with processed wastewater flowing
into
the drainfield pump basin (D). A pump located in the drainfield
pump basin doses effluent to a shallow narrow drainfield
(E). |
