In recent years we have been moving towards more and more industrial development. Dairy industry extremely polluting food industry as the Dairy industry forms strong waste water which is describe by high BOD, COD, Nutrients, inorganic content and biodegradable material that can disrupt aquatic and terrestrial ecosystems. The waste water coming out from this highly processed industrial processes which are rotten in nature. Hence treatment of such waste water is essential before disposal in to river, stream etc. The UASB study gives the approximate idea about the usability and function of the treatment of the waste water of industry by UASB method. The Up flow Anaerobic Sludge Blanket process is one of the recent developments in field of anaerobic treatment. The UASB process is one of the most beneficial & efficient anaerobic treatment. In order to upgrade the quality of an aerobically treated effluent to a level recommended for irrigation, integration of a UASB reactor with AOPs (advanced oxidation processes) could be a better option for almost complete colour, COD removal, and disinfection of pathogens.
