Abstract
Liquid laundry waste is the result of waste from laundry services where the liquid waste contains substances including phosphate (P), calcium (Ca), carboxyl methyl cellulose (CMC), plant oil, clothes bleach, phosphate, surfactant, SiO32-, Total Suspended Solid (TSS), and Chemical Oxygen Demand (COD). Laundry liquid waste can pollute water bodies causing damage to aquatic biota, plants and humans who consume the water, and laundry is rich in phosphate content which can cause eutrophication and algae explosions in water bodies if not treated.Liquid Waste Treatment process Laundry using a Nanofiltration Membrane with Coagulation Flocculation and Microfiltration as Pre Treatment. This study was used to determine the effect of pressure variations and operating time to reduce levels of COD, TSS, Phosphate, and Detergent. The best results obtained from this study were the removal of COD, TSS, Phosphate, and Detergent at a pressure of 6 bar and an operating time of 140 minutes, which had a rejection percentage of 89.15%; 81.53 ; 60,20 ; 52.15 ; with COD, TSS, Phosphate, and Detergent concentrations of 64 mg/L, 65 mg/L, 6.5 mg/L, and 6.8 mg/L, respectively. Key words : Nanofiltration (NF), Microfiltration (MF), COD level, TSS level, MBAS level (detergent), Phosphate level, Combination of Membrane.
