  • The purpose of this study was to design a laundry wastewater system process using filtration method with ceramic filters. The filters were made from natural clay and zeolites in various compositions. The experimental rig was equipped with silica and carbon active filter, ceramic filter module, rotameter, pressure gauge, and a circulation pump. The tested liquid waste was derived from one of the laundry industries in Palembang, South Sumatera, Indonesia. Process variables studied were the operating time and the filters composition. Parameters analyzed were total dissolved solid (TDS), pH, Electrical Conductivity (EC), Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD5) and the concentration of linear alkylbenzene sulphonate (LAS). The obtained results showed that ceramic filters combined with silica and activated carbon as pretreatment can reduce the TDS, EC, COD and BOD5 to 7.3%, 12.6%, 85%, 90% respectively. The system was also able to reduce the LAS concentration in detergent wastewater up to 97%.
