Kinetics Study of Sewage Sludge Treatment by Ultrasonic Membrane Anaerobic System (UMAS)
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 12
Abstract
Pilot scale ultrasonic membrane anaerobic system(UMAS) was studied to determine the kinetic parameters for sewage sludge treatment process. Monod, Contoise and Chen and Hashimoto are the three models which were used in this study. Seven steady states were run at mesophilic temperature and the operating pressure was maintained between 1.5 to 2 bars. The growth yield coefficient Y and the specific microorganism decay rate bwere found to be 0.391gVSS/gCOD and 0.012 day-1 respectively. The parameters of the three models were calculated such as for Monod equation parameters were Ks0.654mg/l and K 0.312gCOD/gVSS.day. Contoiseequation parameters were B=0.212 gCOD/gVSS and um=0.287. For Chen and Hashimoto model the parameters as K=0.294 and µmax=0.312 day-1.The three modelswere successfully fitted tothe system and have shown good prediction. The correlation coefficient was 94 for Contois, 91 for Monod model and 93 for Chen and Hashimoto model.
