Treatment of Carwash Waste Water and Its Reuse to Manage Water Supply

Abstract

The current problem to water supply is the contamination of water resources by pollution. water pollution generally known to be caused by Domestic and Industries there are also some more Auxiliary units which producing more waste water which is not perceived yet as a cause of waste water . In that Car wash waste water is the major producer of waste water which is let untreated in to water bodies. Transportation of people now uses mostly personal vehicle which leads to increase of more number of individual transport mode. In that particularly usage of car as well as its maintenance leading to create more waste wash water and also utilizing more volume of water for that purpose impact the environmental water balance in many ways as the conventional treatment of waste water costing more they are not think about treatment, So in this work the two samples was collected, and initial characterization was done and it was treated by Adsorption method with different Adsorbent which could be prepared from low cost and easily available material. For this work Prosopis juliflora leaves (AD1)and Casuarina equisetifolia (AD2) leaves were used as adsorbent and waste cotton cloth(AC1) which is cellulosic fiber rich in carbon content was used to prepare Activated carbon The treated water was found to be in excellent reduction level of various pollutant level as follows, the level of TSS showed 94.5% &BOD 95.4% ,COD 96.6% was reduced for the sample 1 . The pollutant due to the usage of detergent, that is the Methylene blue Anionic substances level also reduced from 1.8 mg/lit to 0.2 mg/lit of about 88.89%by prepared activated carbon(AD1).and very good reduction level of Oil and Grease was resulted by AD1,AD2,AC2 99.5%, 98.7%, 99.1% It is evident from the result that the waste cloth material and the un wanted growth of Prosopis juliflora which has been insisted to cut down of save underground water could be used in another way for treating waste water and and to solve the problem of water management and supply.
