“…In all cases, ozone treatment was found to be more efficient at higher temperature. The colour reduction of the textile wastewater observed in this study could be explained by the decomposition of high molecular weight dyestuffs to many small organic molecules such as aldehydes, ketones and acids [22] due to ozonation. The removal efficiency of COD, however, did not improve very much when the temperature was increased from 40 to 50 °C.…”

Ozonation in batch experiments were conducted at elevated temperatures to study the influence of temperature on the efficiency of ozonation. The effect of temperature on ozonation was determined by measuring the extent of colour removal and the reduction of chemical oxygen demand (COD) and total organic carbon (TOC) of a textile waste effluent. It was found that increasing the temperature causes a decrease in the levels of colour, COD and TOC. Complete mineralisation of the dye molecule, however, did not occur to an appreciable extent. The efficiency of colour removal was 71.3%, whilst the COD and TOC reduction efficiency was 20.3 and 19.3%, respectively, at the highest temperature studied (50 °C). The removal efficiency of COD, however, did not improve significantly when the temperature was increased from 40 to 50 °C.
