UASB REACTOR PERFORMANCE EVALUATION BASED ON HEIGHT
Height is an important feature of the UASB reactor. In a simple UASB reactor due to movement of methane in the upward direction, the activated sludge around it also moves in the upward direction, which increases the risk of losing the biomass. This can affect the performance of the UASB reactor. Keeping this fact in mind, we have to increase the height of the UASB reactor for getting the advantages of the gravitational force. This increase in height has some other effects. In this paper we have determining the effect of the height on the performance of the reactor i. e., the effect on the percentage COD removal. From this research we found that UASB is showing plug flow type of behavior, shows axial conversion. We found that the COD removal decreases with the increasing height at HRT of 6.7 h.
