Decentralized wastewater treatment system

Abstract

An increase in population, rapid urbanization and quick economic expansion are exerting pressure on the scarce water bodies globally. Untreated wastewater from human settlements reaches natural waterways and cause water pollution. Thus, affects the direct availability of freshwater for human consumption. The need to treat wastewater is important but how to treat the wastewater is to be discussed. Providing the most efficient and affordable wastewater treatment plant is the main challenge. Hence, selecting the right system should be considered along with many aspects such as financial investment, noise protection, operational costs and environmental issues. This paper describes about the wastewater management and decentralized wastewater management. This paper presents a number of technological options and considers their implication for decentralized wastewater systems. Keywords: Wastewater treatment plant, DEWATS
