Physico-Chemical Water Quality Parameters Analysis on Textile

Abstract

Abstract The prevention of pollutants from textile wastewater is important to ensure a healthy life and sustainability of local development. This paper aims to determine the concentration of the physico-chemical water quality parameters in textile wastewater taken from a textile factory at Sri Sulong, Batu Pahat, Johor of Malaysia. The samples were directly brought to the laboratory for analysis, and the content of textile wastewater quality was characterized using physico-chemical analyses including temperature, pH, electrical conductivity (EC), turbidity, dissolved oxygen (DO), chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS), colour, alkalinity, total dissolved solids (TDS), and heavy metals (cadmium, copper, ferum, manganese, lead, and zinc). The results also indicated some of the parameters for final discharge textile wastewater could not be safely discharged because they did not comply with the standards of Standard B such as COD, BOD, colour, TSS, cadmium, and zinc. The results of this studies showed that the concentrations of COD, BOD, colour, TSS, cadmium, and zinc were between the range of 55 - 294 mg/L, 7.1 - 85 mg/L, 17 - 140 mg/L, 69 - 205 mg/L, 0.001 - 0.047 mg/L, and 0.488 - 2.220 mg/L respectively, higher than the values in Standard B. Textile wastewater is classified by pollution severity as strong wastewater. This study provides an understanding and assists in selecting suitable treatment for textile industrial wastewater prior to discharge to comply with the standard permissible of the environmental quality act.
