ASSESSMENT OF WATER QUALITY STATUS OF YAMUNA RIVER AND ITS TREATMENT BY ELECTRODE BASED TECHNIQUES
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 2
Abstract
The objective of this study is to reveal the present condition of pollution level of the water of Yamuna River in Delhi due to direct injection of untreated domestic drains and industrial effluents. Very expensive water treatment technologies are not capable for the treatment of polluted Yamuna river water and the conventional water processes based on chemical, filtration and/or biological treatment process are also not suitable to remove TDS. Generally untreated wastewater contains high level of organic and inorganic materials, numerous pathogenic microorganisms, nutrients and many other toxic compounds. Delhi has been suffering the problems increasing amount of sewage water and industrial effluents into Ymuna river for the last few decades due to horizontal and vertical expansion of the city. Yamuna river is main source of water to well qualified, high populated Delhi peoples and Agra canal originated from Okhala barrage. The water quality was good in the sites where the river enters into the Delhi stretch before the Wazirabad barrage while the river becomes highly polluted after the discharge of various drains into it. In the present study the impact of urban runoff on the water quality of Yamuna River at Delhi has been investigated which supplies into Agra canal for irrigation purposes. Water samples were collected from five different points and analyzed for various physicochemical parameters. Electrochemical technique was successfully applied to the treatment of each sample and the concentration of selected parameters reduced considerably to the admissible limit. Experimental results reported that drastic variations were found in each water samples after treatment. Indicating water pollution levels was manifold higher than the prescribe limit by the pollution control authorities for irrigation. Overall, the study concluded that water quality of Yamuna river water was polluted and not suitable for any other purposes.
