M biological reactors (hereinafter – bioreactors) are on-site aerobic continuous-flow wastewater treatment plants factory produced from extrusive polypropylene with active sludge for biological removal of organic pollutants (BDS and ChDS), nitrogen and phosphorus from household and industrial wastewater, which chemical compositions are similar.

A bioreactor consists of anaerobic – anoxic, aeration zone and secondary sedimentation tank. All zones are installed in a single horizontal repository of cylindrical shape and are separated by walls. By means of the air blower the excess sludge is removed into sludge stabilizer, which is mounted in a separate repository. The treatment unit includes an air blower mounted next to the plant. The shape, configuration, arrangement of treatment stages and equipment of bioreactors installed are analogous to all AT75 – AT250 models. Along with the increase in the capacity of bioreactors, the corresponding structural parameters of the equipment are increased.

Technology bioreactor of the plant contains integrated all levels of biological treatment and sludge sedimentation (anaerobic – anoxic, aeration zone and secondary sedimentation tank). All zones are installed in the aero tanks of rectangular shape, which base is made from concrete and partitions – from polypropylene.

Compared to the traditional treatment methods, our technology is superior to both space and energy efficiency. Treatment system is flexible as the duration of all treatment stages can be easily changed and adjusted. The treatment plants of this type are fitted for treatment of unequal and varying wastewater debits and loads. Plants of the technology are compact, and that is why it is possible to build them in premises. Technological processes in treatment plants are concerted in between and work in interactivity with each other. Intervention of people is necessary only in case of damage or in case of over programming working conditions.
