Water Pollution and Its Prevention Through Development of Low Cost Wastewater Treatment System

Abstract

The development is essential part of human society which offers the opportunities in the sectors like information technology, supply chain, food-farming, infrastructure and more others. Since, last several decades universally the living standard of the human society is upgrading. Currently available and upcoming smart technologies will reduce the efforts involved in day to day activities. The development of society is endless process with respect to the time. Due to depletion in water availability will affect the rate of development and burden on water sources. This burden can be optimizing through reuse of treated wastewater by low cost Decentralized Wastewater Treatment System (DWATS). In this paper the said system is developed by using locally available materials and discussed its performance. As per guidelines of USEPA 2012 for water reuse the pH ranges with 6.5–8.4, TDS ranges from 450 to 2000 mg/L and Electrical Conductivity (EC) 0.7–3.0 µs/cm. The experimental result has pH at inlet 7.78 and 6.4 at outlet whereas The Total Dissolved Solids (TDS) is 116 mg/L at inlet to 86 mg/L at outlet of system. The Electrical conductivity (EC) observed 213 µohm/cm at inlet to 163 µohm/cm at outlet with 23.47–27.85% change in conduction and 57.69–86.41% in BOD where as 66.67–69.96% change in COD when tested at inlet and outlet.
