ABSTRACT

Anaerobic treatment is widely used around the world as a biological stage in both domestic and industrial wastewater-treatment plants. The degradation process of organic matter is more effective compared to conventional aerobic processes and produces less sludge, hence reduces the cost associated with sludge disposal. Among anaerobic technologies, the most popular ones is the upflow anaerobic sludge blanket (UASB). This study reports applicability of UASB reactor to treat the wastewater from industrial belt of baddi, nalagarh, dist. Solan in H.P. The average COD of the wastewater varied between 13,000 – 20,000 mg/l over the study period. Wastewater was diluted to achieve the desired organic load. The feed for the reactor was prepared using wastewater and cowdung extract with COD strength of 2000 mg/l. The removal efficiency of soluble COD and BOD ranged between 30-55% .The Volatile Fatty Acids (VFA) concentration ranged between 150 to 350 ppm in the reactor. Less concentration of VFA indicated proper methanogenesis within the reactor as most of VFA was converted into the methane and Co2.
