A Review on Textile Wastewater Characterization in Bangladesh

The textile and apparel industries in Bangladesh are playing an utmost important role offering tremendous opportunities for the economy of Bangladesh. But, hasty and unplanned clustered growth of industries leads to adverse environmental consequence in an alarming way. This work is aimed at giving emphasis on the present pollution scenario in Bangladesh due to textile effluent. The liquid effluents from industries are causing major havoc to the environment, ecology, agriculture, aquaculture and public health since the development of textile industries in the country. In this paper, effluent characterization results of last ten years (2005-2014) are focused. We found physicochemical parameters of Textile effluents in Bangladesh as, Temperature (25-65°C), pH (3.9-14), TDS (90.7 - 5980 mg/L), DO (0-7 mg/L), COD (41-2430 mg/L), BOD (10 - 786 mg/L), TSS (24.9 - 3950 mg/L) and EC (250-63750μS/cm) from 2005 to 2014. From the available data originated from the study depicts the present pollution scenario in Bangladesh with tremendous violation of laws to meet requirement of waste discharge quality standards. Now it has become a prerequisite to set up ETP in each industrial establishment, particularly at dyeing industries that were discharging huge amount of liquid waste to the rivers every day.
