Biological Treatment of Wastewater, Activated Sludge Process


The wastewater generated from the canteen, mess, college hostel in were collected and analyzed. In the present study, an attempt has been made to evaluate the treatability of wastewaters using lab-scale activated sludge reactor under extended aeration. Studies on the efficiency of the activated sludge reactor were carried out by varying the solids retention time of 8,12 and 16days with various hydraulic retention time of 15,20,25 and 30h with an organic loading rate varying from 0.116 to 0.209 kg BOD/ m3/day. The study revealed that the wastewater is amenable for treatment using ASP, with treatment efficiency as high as 91% and the bio-kinetics arrived at showed, better stability of the system and enhanced microbial activities at longer HRT and SRT. Also the design values suggest that the extended aeration system is the appropriate activated sludge treatment method for wastewater treatment.
