CONCLUSIONS
The activated sludge process is operated best at retention
time of 5 days with BOD percentage removal
efficiency of 95% for dairy wastewater. The treatment
efficiency of the reactor in terms of BOD5 and COD
removals was studied at different retention times and
is used for the large scale treatment plants. The
values of kinetic coefficients based on soluble BOD
are found to be k 4.46 day
