ABSTRACT
Effluent treatment can be carried out by various biological, physical and chemical methods. Physical treatment techniques are used for removal of coarser materials from the water followed by biological and chemical treatments. Removal of many organic matters is generally carried out by biological methods. Biological treatment can be either attached growth or suspended growth. The selection of biological treatment depends on quality of effluent and the percentage removal required. Biological treatments are also used for selective removal of many heavy metals, phosphorous and other pollutants. The current review summarizes the research and advancements in biological treatments.
Key words: organic matter, heavy metals, percentage removal, activated sludge process.
