OPTIMIZATION OF MUNICIPAL WASTEWATER TREATMENT BY UASB REACTOR AND POLISING POND

ABSTRACT

Upflow Anaerobic Sludge Blanket Reactor are mostly designed using empirical formulae derived either from past pilot scale studies or from performance of already existing sewage treatment plants elsewhere. Actual performance of the sewage treatment plant can differ from that of design mainly due to differences in sewage characteristics & local conditions. Anaerobic treatment of municipal wastewater has recently gained worldwide attention due to its effectiveness, low cost, and low energy requirements The Upflow Anaerobic Sludge Blanket (UASB) has been considered the most attractive reactor system due to its simplicity and low operation. Thus knowing actual performance and capacity of the sewage treatment plant becomes very important. This work is concerned with the detailed study of Asia’s largest sewage treatment plant of 345 MLD capacity (based on Up flow Anaerobic Sludge Blanket reactor), installed at Bharwara, Lucknow, Uttar Pradesh, India. The design analysis of the sewage treatment plant has been carried out to comment on the adequacy of design and capacity
