The declining water quality in Sriwijaya University has been caused by the presence of heavy metal contents such as Iron (Fe) and Zinc (Zn) in the treatment and distribution of water. A simple method is proposed in this work to minimize the heavy metal content in water by using filtration technology. This research was carried out using ceramic filter made of 77.5% natural clay, 20% fly ash, and 2.5% iron powder. The results showed an increase in the quality of raw water that is in accordance with the requirement of drinking water standard. The rejection percentage of TDS, Iron (Fe) and Zinc (Zn) content in feed water tended to be high and met the regulation number 492/MENKES/PER/IV/2010 for standards of drinking water in Indonesia.
