Performance of upflow anaerobic sludge blanket (UASB) reactor using anaerobic granular sludge for bioconversion of leachate

Leachate which is defined as the liquid that drained out from the landfill waste, can cause contamination to the environment and also the human health if it leaks and filter through the soil and into the groundwater. Therefore, a proper treatment is needed to overcome this problem in order to reduce...
