Anaerobic wastewater treatment is becoming an accepted technology for treating various types of wastewater. It is frequently used for medium to high strength wastewater (2,000 to 20,000 mgIL COD), but has had fewer applications to low strength wastewater 1,000 mgIL COD) especially in developed countries. In order to understand the applicability of anaerobic treatment for low strength wastewater, such as domestic wastewater, a literature review was performed. The review showed two main variations of anaerobic wastewater treatment techniques (anaerobic filter and upflow anaerobic sludge blanket reactor) and a number of modifications of these two themes in 34 different countries with influent COD ranging from 58 mgIL to 62,000 mgIL.
