TREATMENT AND RECYCLING OF WASTE WATER FROM DAIRY INDUSTRY USING SPIRULINA PLATENSISPATIL NILAM SARJERAO AND KURHEKAR JAYA VIKASAbstract Dairy industry is considered as highly polluting industries in India. Dairy effluent contains high organic load. If partially treated or untreated waste water is disposed off in the natural water bodies, there is a possibility of eutrophication due to high content of elements like Phosphorus,Nitrogen and Carbon etc. Dairy waste is the rich source of proteins like Casein and sugars like Lactose. Biological treatment was observed as effective and eco friendly, as compared to physicochemical process. Bio treatment involves microbial degradation of waste water. Microalgae are known for complete removal of contaminants like Phosphorus, Nitrogen etc. In the current study, Spirulinaplatensis (blue green algae) has been used for the treatment and recycling of physicochemically treated dairy waste water. Open air system was designed for treatment. Spirulinaplatensis was grown for 28 days in physico chemically treated waste. The process was found to be environmental friendly and low investment. Chlorophyll, protein and carbohydrate content of the Spirulinaplatensis was studied and found increased at various concentrations like 20% to 100% during the treatment period.The aim of present investigation was to estimate the application of Spirulinaplatensisin treatment and recycling of waste water from dairy industry. |
