Abstract A laboratory-scale study was conducted to investigate the performance of anaerobic hybrid (combining sludge blanket and filter) and UASB (Upflow Anaerobic Sludge Blanket) reactors for the treatment of distillery spent wash. The start-up and granulation study demonstrated that early start-up and granulation were achieved in case of · A typical UASB reactor consists of the following compartments the sludge bed the fluidized zone the separator and the settling zone. Wastewater enters from an opening (influent) at the bottom of the reactor and leaves via another opening (effluent) at the top. The sludge bed contains granular sludge that is formed from diverse microorganisms.

· reactor . Two laboratory scale UASB reactors were operated in parallel at ambient room temperature of 25-29°C for the treatment of petroleum refinery wastewater. Each reactor volume was 2.36L and fed the biomass obtained from local palm oil mill For this laboratory scale experimental study lab scale UASB reactor was fabricated by using glass sheets with 14 L total working volume. UASB reactors have either a round or rectangular shape.

A laboratory-scale UASB reactor treating winery wastewater was used by Ronquest Britz (1999) to investigate the effect of low pH on the performance. The effect of pH is particularly important for the treatment of winery wastewaters as they often have to undergo neutralization which is an extra cost. Up-flow Anaerobic Sludge Blanket (UASB) reactors are popular tools in wastewater treatment systems due to the ability to work with high feed rates and wastes with high concentration of organic contaminants.
