Efficiency of reactors composed of plant based absorbents in combination with sand and gravel for physicochemical parameters of different category water

Abstract

According to the world Summit of sustainable Development, the major reason for lack of safe water is either scarcity of water or contamination of water sources. Therefore this study eye on developing nations, seeks to find sustainable, yet economically and socially practical solution to the problems associated with polluted water. To fulfil the objectives of the present study, two medicinal value plants Dhav (Anogeissuslatifolia wall.) and Aragvadha (Cassia fistula Linn.) were selected and absorbents were prepared from the bark of both the plants. Then the reactors were prepared using the different compositions of sand, gravel, absorbents of Dhavand Aragvadha and cotton.In this way four filter reactors were prepared. The feeding rate of raw water is maintained at 0.5 litre per hour. The results revealed that Dhav plant absorbent was found more effective thanAragvadha. All reactors shows different efficiencies for different parameters suggesting that reactors should be prepared based on need or targeted parameters. Over all reactor 4 shows better efficiency for all the parameters. The main exclusivity of the present reactor is low cost with no electricity demand. The prepared reactors are environment friendly and easily implementable but further study is required to prove it on large scale.
