Abstract
The dairy industry discharges a large volume of waste water which are reported to cause serious pollution problems. Faced with more stringent legislation and hence higher treatment and discharge costs, there is need to critically examine the techniques employed for its management. For this purpose, the tone is set up by giving an account of the characteristics of dairy wastewater generated by the dairy industry, which indicate the need for its treatment. Thereafter, different biological treatment methods including the methods producing high value products are discussed, including their advantages and disadvantages.
