COMMERCIAL – GROUP SCHEMES UNIT DATA AND SIZES
Group schemes and commercial applications use the AT-75 to AT-400 biological reactors. The larger bio-reactors consist of anaerobic – anoxic, aeration zone and a secondary sedimentation tank.
All zones are installed in the single horizontal cylindrical unit and are separated by internal baffles. By means of the air blower the excess sludge is removed into the sludge stabilizer, which is a separate unit.
The treatment unit includes an air blower mounted next to the plant.The shape, configuration, arrangement of treatment stages and equipment of bio-reactors installed are analogous to all AT-75 – AT-400 models. Along with the increase in the capacity of bio-reactors, so is the corresponding structural parameters of the equipment.
