Abstract
An apparatus for wastewater treatment, includes a calorie reducer first vessel having an inlet and an outlet, the outlet adapted to control the retention time of wastewater within the first vessel. A first recycle pump is connected to the first vessel to recycle wastewater from a bottom of the first vessel to a top of the first vessel through a recycle conduit, at a high velocity. The recycle conduit provides an air gap for drawing air into the first vessel. Bacteria within the calorie reducer vessel consume biodegradable food with a minimum number of bacteria while in the log growth phase. A second bio-reducer vessel is connected to the calorie reducer vessel. The bio-reducer holds a media supported above a bottom reservoir. A bio-reducer recycle pump recycles wastewater within the reservoir to be sprayed onto a top of the bio-reducer, to wash over the media. Further bio-reducers can be arranged downstream of the first bio-reducer. In the bio-reducers, protozoa attached to the media consume the bacteria which wash over the media.
