AB  - Filtration is a separating process between solids and fluid, either liquid or gas, using a porous medium or other permeable materials. Filtration is used to remove the suspended solids and colloids as much as possible. In filtration process, water seeps and passes through the filter medium. The suspended solids will be accumulated on the surface of filter and collected throughout the depth of the medium. Quartz sand is an excellent medium for water filtration. In this research, Malimpung quartz sand was used as the single filter medium. The sand comes from Malimpung, Pinrang, South Sulawesi Province, Indonesia. The purposes of this research are to analyze the effectiveness of Malimpung quartz sand at the flow rate and turbidity level using a single medium filter. The experiment method consists of two stages. Firstly, testing of the sand whether meets the filter medium standard or not. It was performed at the Soil Mechanics Laboratory of Hasanuddin University. Secondly, testing of the sand in a filtration apparatus. We used two unlike types of diameter: uniform and non-uniform grain diameter. Moreover, we used three different thickness of filter medium: 50, 60 and 70 cm. The results showed that the Malimpung quartz sand meets the standard of filter medium with value of U<SUB>c</SUB> as 1.7 and G<SUB>s</SUB> as 2.66 (g cm<SUP>-3</SUP>). The effectiveness of the sand can be seen from the large output discharge and low water turbidity level.
