In the present study, Phenol and other chemicals are of reagent grade were
used without purification. The desired concentration of phenol solutions was prepared
by using distilled water.
During start up operation, the sequential batch reactor was filled with sewage
obtained from activated sludge unit from local industry. Culture was incubated for
developing the biomass. Synthetic sewage having the constituents indicated in Table 1
