HYBRID CHEMICAL METHOD OF TREATING EFFLUENTS GENERATED BY RICE MILL: A SIGNIFICANT APPROACH FOR CONTAMINANTS REDUCTION

Abstract

Life cannot be imagined without water and is necessary for the existence of life its role is in maintaining the balance of ecosystems is remarkable. We are state of lacking fresh water for various use, it is mandatory to opt for sustainable and recycling method for this kind of scarcity. Rapidly growing population significantly demanding for over production of grains, that results increasing grain processing industries to convert the whole crop into edible form. As our state Chhattisgarh stands seventh position for paddy crop production across the country, there are numerous rice mill for its processing thereby utilizing fresh water and generating huge effluent that are discharged either partially treated or untreated. Approximately 1 kg of paddy processing into edible grain form generates 1 liter of effluent. Aquatic as well all ecosystem is highly effected by this kind of activity. Living beings are connected to each other through food chain and depletion in WQI highly effects humans as well as all ecosystem. The present paper suggests the cheapest as well as sustainable hybrid chemical methods to minimize contaminants. Individual lime and hydrogen peroxide treatment methods was not that much efficient for all physio chemical parameters that defines the water quality index. Despite combination of both treatment method results into good change in every parameter.
