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.

Biological waste treatment process and apparatus

An oxidation ditch for biological aerobic treatment of wastewater having a velocity control system to establish an increased and more uniform cross-sectional velocity throughout the flow channel. The system includes a turning baffle member positioned in at least one of the end sections of the flow channel. The turning baffle member is provided with an end portion that has an upper edge that extends under a brush aerator located across an elongated section of the flow channel. The upper edge of the other portion of the turning baffle member extends above the surface of the flowing mixed liquor stream. The flow of the mixed liquor downstream of the brush aerator is unrestricted by flow baffles located in the flow channel.
