Abstract :

Textile industries in Bangladesh produce a great amount of effluents, as a byproduct. Despite many regulations set by the DoE to make sure that the textile factories treat their effluents according to the quality standards, many of the existing textile factories do not follow it. Some of the main reasons for not following regulations include the lack of financial resources, and lack of knowledge, and lack of expertise in maintaining an effluent treatment plant. This work aims to provide a basic understanding of the three most commonly used ETP in textile industries in Bangladesh. They are the physico-chemical ETP, biochemical ETP and biological ETP. The concern of this study was to evaluate the three ETP based on their ecological, economic performances as well as to compare their efficiency in treating textile wastewater to the quality standards. The result found by conducting extensive analysis of quality parameters before and after treatment as well as the rigorous calculation of financial aspects (Break-even point analysis) of the three ETP, helped this work to firmly conclude that the biological effluent treatment plant is the most sustainable option for treating textiles wastewater in Bangladesh.
