2 PROCESS DESCRIPTION
System Components
Sedimentation Chamber
This chamber is designed to physically separate the solids from the incoming water.
Anaerobic Filtration Chamber
This chamber contains a spherical-skeleton type of filter media. Through bacterial growth processes
on the surface of the filter media, biological anaerobic treatment thrives while suspended solids are
captured. The bacteria in this chamber convert nitrates in the recirculated water returning from the
aerobic chamber to gaseous nitrogen. The nitrogen then escapes to the atmosphere.
Aerobic Contact Filtration Chamber
The aeration chamber consists of an aeration upper section with contact media plates and a filter
media lower section. In the upper section, the board contact media adjusts inflow from the anaerobic
filtration chamber and organic matters are decomposed by micro-organism/bacteria on the contact
media surface. Also, organic matters are decomposed by micro-organism/bacteria on the filter media
surface while suspended solids are captured in the lower section. Suspended solids accumulated on
the bottom are constantly transferred to the sedimentation chamber by a recirculation air-lift pump.
Storage Chamber
This chamber is designed to temporarily store the treated water coming out of the aeration chamber.
The treated water is pumped out to the disinfection chamber by an air-lift pump.
Disinfection Chamber
The treated water from the storage chamber passes through the chlorinator for final disinfection. After
disinfection, the treated effluent is stored in the disinfection chamber.
