چکیده مقاله
The Dairy Industries are growing on a rapid pace globally It produces a large quantity of wastewater with a high concentration of milk constituents such as casein, lactose, fat, inorganic salts along with detergents and sanitizers which contribute towards high BOD and COD Therefore, the treatment of dairy wastewater attracts increasingly more attention There are many ways to reduce the BOD and COD, but biological treatment is the primary mean Both aerobic and anaerobic technologies have been used, while anaerobic treatment of wastewater has emerged as viable and economical alternative over the conventional aerobic treatment particularly for high BOD In aerobic technologies number of different treatment methods are there like, activated sludge, sequencing batch reactor, rotating biological contactors trickling filter In anaerobic treatment methods are up flow sludge blanket UASB , anaerobic sequencing batch reactors ASBR , continuous flow stirred tank reactor, hybrid anaerobic digesters, contact reactor, up flow and down flow anaerobic filter, and two stage systems that separate the acid forming and methane forming There are many cases where aerobic and anaerobic processes are combined in onesingle treatment system Membrane technology is alternatives to bio treatment being used for BOD reduction in dairy wastewaters which replaces secondary clarifiers in the waste treatment plants with membranes
