Financial analysis of alternative effluent management in textile industry

Abstract

Textile businesses are rapidly emergent in Bangladesh and consequently the textile dyeing factories also increasing and consequently the generation of wastewater as pollutants also rises. The Effluent treatment plant has significant impression on environmental reservation. The functions of ETPs are taken as non-productive because they have no market value these prosperities and often left uncalculated. The study was conducted to develop the financial and environmental benefits, using the financial analyzing parameters, quantification of the three (biological, physicochemical and electrochemical) different ETP project and correlate it with operational efficiency. This necessity of setting up functional ETPs became a major demand from the buyers and thus relates with the sustainable development of the sector. NPV, AE, IRR and Payback period analysis most common and more widely accepted economic parameters in view of the fact that those are standard and systematic decision-making support tool. The secondary data samples of effluent were collected from the selected nine factories to analysis the individual laboratories for parameters, including pH, DO, EC, BOD, COD, TDS, TOC and TSS. The study provides economic rationalization of the justification without any reservation for biological, Physicochemical and Electrochemical ETP and also the treatment efficiency of the particular type. The study provides the comparison of decision parameters for those three different treatment plants. The result reveals that biological treatment plant is cost-effective than physicochemical and electrochemical. The study also calculated that least amount pollution in the discharge channels for electrochemical treatment plant. As a result, the waste water treatment plant project is significantly sensitive to the changes in project diversity. Once the efficiency of the project, as well as environmental benefits, is estimated and the financial analysis of the treatment processes are known, any textile industry will be able to calculate the benefits and impairment of the project.
