Clean Water: Design of an efficient and feasible water treatment plant for rural South-Bengal
Avijit Mallik, Md. Arman Arefin
ABSTRACT: Wastewater treatment is an important issue because of lessening water resources. The primary reason for wastewater treatment process is to expel the different constituents of the polluting load: solids, natural carbon, supplements, inorganic salts, metals, pathogens and so on. In this paper, the mainly de-centralized method is considered as a solution. A new rural wastewater treatment process is introduced with proper planning and designing by using empirical equations. This paper exhibits the wastewater treatment technologies present in Bangladesh, to expel contaminants from wastewater, for example, halogenated hydrocarbon mixes, overwhelming metals, colors, pesticides, and herbicides, which speak to the fundamental toxins in the wastewater. This research shows that the proposed decentralized system is more feasible economically and environmentally (about 75% BOD removal) since the centralized system needs modern machinery and high initial investment. To design a sustainable wastewater treatment system for developing an area, further assessment of environmental, health, social and institutional aspects are recommended.
