“…As there are some disadvantages of aerobic treatment like high energy required through aeration, and e ciency is less due to growth of microorganisms (Sivakumar, et al 2012). Anaerobic treatment is an e cient method to degrade organic constitutes with the help of microbes in the absence of oxygen (Kalat et al 2017). In anaerobic digestion process involves two steps like stabilization and degradation with the help of microbes (Chatzipaschali et al 2012).…”

Dairy industry is one of the leading consumer of water and producer of wastewater. Increased demand of dairy products results in rapid growth of dairy industry and hence wastewater production increases. Dairy effluent contains high concentrations of organic and inorganic substances that cause eutrophication in water bodies. This review study emphasizes on various treatment methods of DWW for period 2002 to 2021. Dairy wastewater imposes serious environmental concern because of the presence of wide range of fatty acids, proteins, nutrients, and other organics. These contaminants are difficult to treat in single step conventional treatment technique. In recent years much attention has been given for integrated system of dairy wastewater (DWW) treatment. The present review has deep insight for ongoing development in various treatment techniques of dairy wastewater. Moreover, this article intricate issue related with treatment followed by a brief discussion on the biological technique and special emphasis has been on the bio-filtration process. Extensive review study found that bio filtration method is environmentally sustainable and economically affordable technology as it requires minimal maintenance and low operating cost; filter media can be coarse gravel, stone, bio-carrier. Literature survey found that the bio-filtration process has the efficiency of removing BOD, COD, TP, TN (91.7–97.5, 74.1–99%, 98.3%, 88-91.5%). Fresh water crisis demands the reuse of DWW for non-potable purposes. Reuse of DWW in food, plastic, fuel, health and pharmaceutical industries helps to convert its zero value to a potential resource.

“…Anaerobic treatment of dairy waste waters is a complex process that degrades the organic matter by the variety of intermediates and utilizes microbial consortium in the absence of oxygen. It is an important approach in the reduction of pollution and waste [67]. This type of treatment is considered to be an excellent process by several researchers when compared with the aerobic process [68].…”

Dairy products are one of the richest sources of vital nutrients in the diet of human beings and it occupies an important place in satisfying their nutrient requirements. The dairy products possess a very short lifespan and during their decomposition create a huge nuisance to the environment. The dairy effluents discharged from the industries are mainly composed of complicated substances such as organic compounds, inorganic compounds, carbon, nitrogen, phosphorus, chlorides, sulphides, fats, oils, grease, etc. These organic loading present in the dairy effluent have a negative impact on the environment during its discharge to nearby water sources. The physical and chemical treatment of the dairy effluents is not as effective as the biological treatment. The biological treatment method is found to be the superior method for treating the dairy effluent. The biological wastewater treatment can be performed in two various conditions such as aerobic and anaerobic. The treatment methods such as aerobic lagoons, activated sludge, sequential batch reactor, trickling filter, completely stirred tank reactors, fluidized bed reactors, and anaerobic filters are some of the biological methods used in dairy effluent treatment. This review article has investigated in detail regarding the environmental impact of dairy effluents and their effective treatment using biological treatment technologies
