From the review, India was developing country but still used the old conservancy system at various places, particularly in villages and towns for the treatment of the waste water generated. Although the anaerobic treatment of waste water had been implemented since the beginning of the century, yet conventionally, the anaerobic process was well-thought-out to be a slow process, requires the digesters of large hydraulic retention time (HRT). However, the high rate anaerobic system had been devised and constructed to treat concentrated municipal waste water. The various high rate anaerobic systems had been devised including Upflow Anaerobic Sludge Blanket (UASB) reactor. The objective of this paper was to design a UASB reactor for the campus of Government College of Engineering, Jalgaon (GCOEJ) Maharashtra, India. The increase in the sludge retention time (SRT) minimises the sludge production but this however, tend to increase the reactor volume. On the contrary, minimum HRT minimises the reactor volume. Hence, during the design, a proper balancing between these two components was taken into account along with establishing the intimate contact between the incoming waste water and the detailed biological solids in the reactor and maintenance of sufficiently warm temperatures. The UASB model showed promising results in removal of BOD, heavy metals, pH, turbidity and decrease in microbe content. After characterization of these properties, proper treatment plant was designed and dimension calculated. Diameter of collection pit was calculated to be 6 m and depth to be 5 m. A UASB reactor of diameter 5.5 m and height 5 m was designed such that the amount of methane produced at the end would be 343.852 m3/d with the daily addition of alkalinity in the form of Sodium bicarbonate of 494.032 kg/d would require to maintain the pH in the reactor.
