INTEGRATED WASTE WATER TREATMENT ACCOMPANIED BY MINIMAL GENERATION OF EXCESSIVE ACTIVATED SLUDGE OR SEDIMENT

The authors have demonstrated the possibility of development of a process technology of treatment of domestic and similar types of sewage waste water accompanied by minimal generation of excessive activated sludge or sediment using bioreactors that have biomass attached to them. Wet sludge rate reduction is driven by intensification of aerobic stabilization. The article has experimental data generated in the course of the project implementation. There are various aspects to be considered, including technical, economic, social and ecological issues. According to the above, there is a strong need for a combination of proper waste water treatment methods that contemplate minimal sludge formation and further use of sludge. One of the ways to attain the above goal is to use the biomass in the aeration tank. The experiments were held by MGSU Department of Waste Water Treatment and Water Ecology. The authors provide the design scheme of the facility and other parameters of the experi ments held. A combination of aerobic and anaerobic processes helps provide the proper quality of integrated biological treatment. Chambers of the aeration reactor are also equipped with the polymer feed of various compositions. Sludge treatment that is also strongly needed was performed by means of aerobic stabilization accompanied by ejecting aeration. The experiment findings demonstrate its substantial effect in terms of both components, including sewage and sludge treatment
