PHYSICO-CHEMICAL PROCESS OF WASTEWATER TREATMENT IN THE SUGAR INDUSTRY

Abstract

Sugar industry is an important industry in India and one of the most important substrates of human nutrition. Sugar plays an important role in our daily life. Sugar Industry Various chemicals are used in the production of sugar. In addition to chemicals, water also plays an important role in the sugar manufacturing process of the sugar industry. In the sugar industry, two types of water are used in the production of sugar. First internal water (cold water) and second internal water. External water such as cooling water is used to condense and cool power plant turbines, mill turbines, mill bearings, crystallized sulfur burners, air compressors, vacuum pumps, hot liquid pumps, etc. The agricultural sector and industry are major sectors with water consumption rates of freshwater supplies indicated by the ubiquitous nature of sugar production and require large amounts of freshwater. Freshwater is used in various units of the sugar manufacturing process in sugar mills, producing wastewater that varies greatly in both quantity and quality. Wastewater from these sugar industries is treated by biological processes, and wastewater is also treated by physicochemical processes. At present, the sugar factory properly treats and reuses the wastewater.
