Aerobic Anaerobic WWTP Design Simulation in the Jeans Industry to Reduce TSS Levels according to Quality Standards

Abstract

The rapid development of the textile industry has induced an increase in environmental pollution. This is not only harmful to the environment but is also a threat to living things, especially in humans. Dyes from textile waste when disposed into the water, pollute its surface thereby preventing sunlight into it. The level of organic compounds in water can be measured by TSS parameters. In general, the discarded TSS level ranges from about 475 to 678mg/L. According to the Provincial Regulation of Central Java Number 5 of 2012 on Amendments to the Regional Regulation of Central Java Number 10 of 2004 on Wastewater Quality Standards, the maximum allowable level for Textile and Batik Wastewater for TSS is 50mg/L. The Aerobics Anaerobic WWTP Design function is to reduce TSS levels in accordance with quality standards. The simulation results showed that, at the discharge level of 50 m³/day, the initial TSS level of 678mg/L decreases to 40.7 mg/L in accordance with the established Quality Standards and become an environmentally friendly Industry.
