Advancement in Waste Water Treatment by recovery method in Dairy Industry
Dairy industry is such kind of industry where high amount of water is required to process the milk, from raw milk receiving up to dispatch of final product and ultimately results into discharge of large amount of waste water. This waste water generally called effluent comprises of fats, lactose, nutrients, whey protein etc. due to which the biological oxygen demand (BOD) of water increases, along with this due to cleaning of equipments, tank, containers and pipes through various chemicals the waste water also contains detergents and sanitizing agent which leads to increase in chemical oxygen demand (COD). Due to increased BOD & COD, proper treatment of waste water is required before its discharge to prevent environmental losses.
