Phytoremediation using Aquatic Macrophytes for Treatment of Municipal or Grey Wastewater of Kota Rajasthan

Abstract

In recent years the pollution of water has become one of the most significant newlineenvironmental problems in the world. Normally water is never pure in chemical sense. newlineIt contains impurities of various kinds; dissolved as well as suspended matter. When newlinetoxic substances enter lakes, streams, rivers, oceans and other water bodies, they get newlinedissolved or lie suspended in water and get deposited. This results in the deterioration newlineof water quality, which affects the aquatic ecosystems. Pollutants can also seep down newlineand affect the ground waters. Polluted waters are turbid, unpleasant, bad smelling, and newlineunfit for drinking, bathing, washing and other purposes. Sources of water pollutants are newlineof two types, point sources and nonpoint sources. Point sources of pollution occur when newlineharmful substances are emitted directly into a body of water. A nonpoint source delivers newlinepollutants indirectly through environmental changes. The control of water pollution is newlineone of the most important aspects of environmental protection. newlineDomestic wastewater is producing in a huge quantity in almost all the cities of the newlinecountry. Its disposal and treatment has become a challenge for the municipalities. Many newlineof the municipalities in growing cities neither have proper disposal system nor have any newlinetreatment facility due to higher cost. In such a situation domestic wastewater is diverted newlinein to low lying area in to aquatic bodies like ponds and lakes, where it is posing a newlineserious threat to the water quality. Disposal of domestic wastewater in to fresh water newlinebodies is constantly adding nutrients in to water, which is mainly responsible for newlineincrease in the concentration of nitrogen and phosphorus. newline
