Primary milling of rice is the most important activity in food grains. Due to industrialization and global competitive market trends, it has emerged as major industrial activity in small medium sector to cater the needs of increasing population. There are huge number of mills engaged in processing of rice and are spread over in almost all state across the country due to increasing trends. Rice milling is the process of removing the husk and part of the bran from paddy in order to produce the rice for eating. Parboiled rice production generally requires huge amount of water for soaking of the paddy. Waste water coming from rice mill operations contains high concentration of organic and inorganic substance causing significant polluting phenomena. The aim of this study is to understand the extent of water pollution due to the effluents from rice mill.
