Evaluation of Constructed Wetland for Domestic Wastewater Treatment in Rural Areas

Abstract

The constructed wetlands (CW) are the artificial structure which treat the waste water in a natural way. The interaction of waste water occurs with micro-organisms, plants and subsoil which helps to purify the wastewater through physical, chemical and biological processes. In a developing country like India, these constructed can play a vital role to minimize the cost of processing the waste water, groundwater recharge and pollution abatement. Despite its advantages as compared to traditional treatment plant, constructed wetland has several challenges like sustainable operations in low temperature zones, large area requirement in dense population and hilly areas.  This paper evaluates the effectiveness of CW for domestic waste water. The parameter of pH, dissolved oxygen (DO), Temperature, Biochemical oxygen demand (BOD), Chemical oxygen demand (COD) are taken into consideration for processing of domestic waste in remote locations. The data and result obtained in this paper could be evident for development in research work and for live projects typically for domestic waste in rural areas where land cost is not too high.
