Effect of temperature on the Colour and TSS removal of batik dye wastes in an integrated biological and filtration treatment system

Abstract

In this study, conventional filter system (with a polypropylene membrane) was used with L. delbrueckii to treat dye waste from textile waste water. The purpose of this study was to determine the effect of temperature on the colour and TSS removal of dye wastes in an integrated biological and filtration treatment system. Temperature was varied in a range of 33°C, 35 °C, 37 °C and 39 °C and pH was controlled at 6 for 50 wt% dilution of dye. Fourier Transform Infrared Sprectroscopy (FTIR), Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES), color removal, pH profile and total suspended solid (TSS) analyses were done on the dye waste before and after the treatment. The optimum temperature and pH identified for dye degradation were at 37°C and 6 with initial color removal of 22.6% and final removal of 75%. Initial total suspended solid removed was 5% whereas the final removal was 75%.
