Abstract

The study aims to utilize Hybrid Membrane Technology (UF-RO) in reducing contaminants from rubber industry liquid waste to domestic water. The parameters tested were pH, COD, BOD, TSS, NH3-N, Ntotal, turbidity, iron and zinc. The pre-treatment process used was filtration and adsorption. The filtration process used filter columns containing silica sand and activated carbon, while the adsorption process used an adsorbent column containing bentonite. After the pre-treatment process, it was continued with the application Hybrid Membrane (UF-RO). The variables of the study were operating time of 15 to 90 minutes and variations in feed flow rate 3, 5, 7 and 14 L/min. The results showed the optimum removal percentage of turbidity and pH was 99.77% and pH 6.93 at the feed flow rate of 3 L/min at the Reverse Osmosis Membrane, while at the feed flow rate 7 L/min the optimum removal percentage of Ntotal and NH3-N was 94.44% and 98.49%. Furthermore, the optimum percentage removal of COD, BOD, TSS, iron and zinc in the Reverse Osmosis Membrane was 96.95%; 98.50%; 97.26%; 84.86% and 96.29% at the feed flow rate of 14 L/min. Finally, rubber industry wastewater treatment using Hybrid Membrane (UF-RO) was able to reduce pH, COD, BOD, TSS, NH3-N, Ntotal, iron, zinc, and turbidity, and the results were accordanced with domestic water quality standards.
