Rancang Bangun Alat Filterasi Limbah Minyak Pelumas (Oli Bekas) Menggunakan Pasir Zeolit, Karbon Altif Dan Membran Keramik

The increasing use of motor vehicles, the greater amount engine oil consumption. Engine cannot be used continuously due to frictional force on engine, so is purified. Unused can pollute environment because it categorized as B3 waste. Used has a higher metal content than new oil. reduction in done by using filtration column containing zeolite and activated carbon with height 20 cm from each media. Besides filtering also separation ceramic membrane. In columns after that continued membrane, before heated at temperature 70 0 C then flowed this research, decrease levels aluminum (Al), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn) was obtained.
