slugPollution threat to surface and ground water quality due to electroplating units
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2014, Vol 2, Issue 2
Abstract
In Delhi, a significant part of the pollution load to the river Yamuna is contributed by small scale electroplating units. These types of industries are inadequately equipped to deal with the environmental problems in a professional way. The study reflected the most of the elements in the effluent discharged by electroplating units are crossing the limits prescribed by state pollution control board. The heavy load of trace elements in effluents tends to get absorbed easily on surface like soil or sediments of conveyer system which will contaminate the surrounding environment. Three different pockets of industrial area in Delhi were selected for the study. The concentration of Iron, Total chromium, Hexavalent chromium, Nickel and Copper are exceeding the prescribed limits in all three pockets, whereas concentration of Zinc is crossing the limits in two pockets. The concentration of Cyanide is below the prescribed limit in all three pockets. The cost effective treatment technology and metal recovery techniques should be introduced amongst the small scale entrepreneurs.
