Biological sewage treatment plant DBF

The compact activated sludge plant DBF type is a compact plant suitable for the treatment of waste water from civil, industrial and agricultural source with biodegradable pollutant. The plant consists of a tank divided into four compartments, oxidation, settlement, sludge digestion and sludge thickening. The treatment process is articulated into subsequent stages: the raw inlet water is submitted to a first fine screening stage and then conveyed to the oxidation process; the air required for the oxidation is ensured by one or several blowers and a set of manifolds, distribution ramps and air diffusers, suitable for the development of aerobic bacterium colonies able to metabolize the organic substances contained in the water and sludge.
