Abstract
Liquid waste textile industry in general are alkaline, odorless, colorless, contain organic materials and heavy metals that are harmful to humans and the environment. Therefore, besides color, the textile industry wastewater has a high concentration of Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS). Waste water treatment of textile industry can be done in various ways, one of them is by using AOPs (Advanced Oxidation Process). The method can be compared efficiency in reducing the high concentration of COD and TSS by using a method between individual UV, individual O3, or a combination of UV and O3 (UV / O3). In this study, textile industry wastewater treatment was carried out by a separation method using AOPS (Advanced Oxidation Process) with a combination of UV and Ozone (UV / O3).The process will be carried out in a semi batch with various additions of Carbon Nano Tube (CNT) catalyst types of pristine with variation 1 mg; 2 mg; 3 mg; 4 mg; 5 mg and temperature 30 0C during to 60 minutes. Analysis was carried out on the feed solution before and after processing with the method of spectrometry analysis on COD, and gravimetric analysis on TSS. The best % reduction COD concentration is 44,19% was obtained from operating conditions using 5 mg Carbon Nano Tube (CNT) pristine catalyst.
