- Abstract
Water is an important process medium used in cleaning, disinfection, cooling and heating practices in dairy plants. Large amounts of water is used so high amount of organic matter loaded wastewater is obtained during manufacture of dairy products. Dairy wastewater contains cleaning water mixed with milk or milk products poured out during processing and packaging, whey from cheese-making, brine, buttermilk, fat, oil and grease, chemical agents, detergents and sanitizers used in cleaning practices. Dairy wastewater is characterized with its high BOD and COD levels due to high level of organic matter content. Environmental problems can occur when dairy effluents are discharged without treatment or discharge of semi-treated wastewater. Dairy wastewater is treated generally by biological and physicochemical methods. Success of the treatment depends on composition of wastewater. Dairy wastewater can be effectively treated by biological methods due to its nutritious nature. Activated sludge process is the most commonly used technique. C, N and P can be biologically separated from dairy plant wastewater. Activated sludge process is an environmentally friendly, economic and efficient technique when target waste is properly selected. Microbial community present in sludge used during treatment is called as activated sludge. In this review, the properties of dairy wastewater, the principles of activated sludge process and the functions of microbial community used in activated sludge process are stated.
