Dairy wastewaters are generally treated using biological methods such as Activated Sludge Process, Aerated lagoons,
Trickling Filters, Sequencing Batch Reactor (SBR), Up Flow Anaerobic Sludge Blanket (UASB) reactor, Anaerobic
Filters, Moveing Bed Bio-film Reactor (MBBR) etc. Oftentimes the post-treatment of dairy wastewater is also done using
the physico-chemical treatment methods consisting of coagulation/flocculation by various inorganic and organic natural
coagulants, and membrane processes like nano-filtration (NF) and/or reverse osmosis (RO). Membrane processes produce
purified water without milk proteins and lactose and which could be recycled. At the same time the recovered proteins
and lactose can be used for non-human consumption [2]
