Investigation of Water Quality Parameters Discharged from Textile Dyeing Industries

Abstract

Rapid development of textile industry and direct deposition of the effluents into sewage networks produced disturbances in treatment processes and exert pollution loads on water bodies. The study was conducted to investigate the water quality parameters discharged from seven textile dyeing industries at Konabari in Gazipur region of Bangladesh during March to December, 2011, and also to evaluate the harmful effects of effluents on the surrounding environment. Emphasis was given on the investigation of important water quality parameters, which include temperature, pH, total suspended solids (TSS), total dissolved solids (TDS), dissolved oxygen (DO), biochemical oxygen demand (BOD) and chemical oxygen demand (COD), along with the management techniques of effluents discharged from textile dyeing industries. The study depicted that the DO values were nil or below the standard values in all industries which was very alarming for environment. The concentrations of BOD, COD, TDS and TSS were very high which indicate the presence of water pollutants. The study was focused on the pollution implications of effluents from textile industries around the study area, because of the risk of human exposure and environmental degradation by these massive discharged effluents. The water quality deteriorated in dry season than the wet season and the surface water around the studied area was highly polluted due to the industrial activities and should totally avoid for human consumption without proper treatment. It is therefore recommended that the careless discharge of the effluents should be discouraged and appropriate management system should be taken immediately to reduce the water pollution for saving the environment.

Food Adulteration and Bio-Magnification of Environmental Contaminants: A Comprehensive Risk Framework for Bangladesh

“…A recent study investigating the water quality parameters discharged from seven textile dyeing industries at Konabari in Gazipur region of Bangladesh reported the harmful effects of effluents on the surrounding environment (Munnaf et al, 2014). The study concluded that the volume of wastewater discharged from the studied industries often exceeds acceptable standards set by Department of Environment (DOE).…”

An innovation-cycle framework of integrated agricultural knowledge system and innovation for improving farmers climate change adaptation and risk mitigation capacities: A case of Bangladesh

“…It is alarming that in Bangladesh majority of farmers are not trained in pesticides use or handling fertilizers or spraying preservatives, and most of them openly admit to using little or no protective measures while applying pesticides (Dasgupta et a., 2005;Hassan, 2015). This results in increased health and environmental risks due to contamination of water, loss of biodiversity and deterioration of soil quality and toxic elements in the food chain (Huq et al, 2006;Altieri, 2009;Chowdhury, 2010;Khan et al, 2011;Munnaf et al, 2015;Hassan, 2015). A summary of the key risks due to 'risk ignorance' or lack of producers' capacity of risks mitigation is given as follows:…”

Physico-chemical Quality and Efficiency Study of Textile and Garments Effluent

“…Rapid industrialization and direct discharge of industrial effluents as wastewater affects environment and exert pollution load in surrounding water bodies (Munnaf et al, 2014). It has been reported that industrial effluent has hazardous effect on water quality, habitat and complex effects on flowing waters (Ethan et al, 2003).…”

“…It has been reported that industrial effluent has hazardous effect on water quality, habitat and complex effects on flowing waters (Ethan et al, 2003). Industrial wastes and effluents contain toxic and hazardous substances which are detrimental to human health and are considered as threats to the existence of human being (Islam et The World Bank have identified 72 toxic chemicals in our water solely from textile dyeing, 30 of which are cannot be removed (Munnaf et al, 2014). All these chemicals are quite harmful or even fatally toxic to fish (Kumar, 1996) It is well established that pollution lowers the quality of life in various aspects and affects health and life span (Grover and Kaur, 1999).…”
