Oxidation ditch is a well known modification of activated sludge process and comes under extended aeration. The use of oxidation ditches for wastewater treatment is not new. In recent years, however there has been considerable renewed interest in the use of oxidation ditches. Much of the work has been done by different research workers. In this process, aeration is one of the governing parameters. Oxygen transfer rate of rotor aerators can be increased with rotor speed ( Stephenson et al , 1985 ) and using draft tube turbine aerators (Boyle W.C , 1989) In this paper an attempt has been made to improve the oxygenation capacity of aeration system by supporting bubble aeration to the conventional aerators and laboratory study has been made on the performance of oxidation ditch with bubble aeration with reference to domestic wastewater treatment.
