Abstract:
The Study focuses mainly on the impact of Sewage Treatment Plant on the ready-made garment industry. As Most of the factories are not aware of sewage water that actually impacts very badly to the environment as well as water resources. Sewage water can be reused and safely disposed by sewage water treatment plant (very new technology in Bangladesh). As STP is not available in most industries, we found it in Snowtex Group, located at B 65/3, Lakuriapara, Dhulivita, Dhamrai, Dhaka-1350. Specifically We, tried to describe the basic mechanism and function of a Sewage Treatment Plant in this study. We also checked the water parameter and compare it with the standard parameter and able to show how it is compatible with the environment. These specific parameters are Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO), Total Dissolved Solids (TDS), Nitrate, phosphate, Total suspended solids (TSS), Temperature & coliform. We find that the treated water is not harmful and can be reuse to some specific particular purposes. we tried to find out the costing of a Sewage Treatment Plant (STP) and how it affects on this garment factory. As it’s a biological plant, operating cost is minimum. Industrial wastewater is fully organic compound and surprisingly no sludge has been produced as it only produces Carbon and Nitrogen gas which emits into the environment and it’s also safe. After Completing this study, we have found gap in this project such as they have no laboratory for testing treated disposal water every day to check its parameters. We have suggested setting up a laboratory for STP. So that everyday water parameters can be checked. In this study, we tried to show the benefits of a Sewage Treatment Plant (STP) for garment industries and for environmentally it is a must for safe sewage discharge water according to environmental law. After completing this study, our statement of purpose is to show how a Sewage Treatment Plant can be an asset of a factory with its so many environmental benefits and it’s a great practice of Corporate Social Responsibility.
