The compact total oxidation plant activated sludge plant is a compact plant used for the treatment of the waste water from civil, industrial and agricultural origin with biodegradable pollutant. The treatment process consists of two subsequent stages: oxidation stage and decantation stage.
The treatment process is subdivided into subsequent stages: the raw inlet water is submitted to a first fine screening stage and then conveyed to the actual oxidation process; the air necessary for the process is supplied by one or more blowers and is distributed through several supply ramps provided with diffusers for the development of aerobic bacterial colonies able to metabolize the organic substances present in the sewages.
The second stage occurs in a settlement tank and it consists in separating the sludge from the treated water. The sludge is conveyed to the oxidation tank top by means of recycle water ejectors, the treated water instead flows in a lateral channel. The settlement compartment is provided with skimmer units to remove the floating substances. Blowers and electric control panel are housed in a specific room located over the oxidation tank. The plant can be supplied complete with disinfection and filtering unit on sand and/or activated carbon in order to comply with the emission limits allowed by the current regulations even if the plant does not discharge into the sewer. This plant is available in two versions: VRIO and VPIA, the first one with reinforced concrete tank, the second one with prefabricated carbon steel tank. On request, the VPIA version can be produced completely in stainless steel or synthetic materials (PRFV, HDPE, etc).
