The phenomenon of deteriorating water resources is addressed in this study, as such to apply membrane technology in groundwater treatment. This research is initiated by making a tubular ceramic membrane from 10% zeolite as a base, clay varying 30-70%, activated carbon varied from 5-45%, 10% white Portland cement and 5% PVA were used as inorganic and organic adhesives. The membrane is made using the Sintering method at 8000C for 6 hours. This study aims to apply ceramic membranes designed to reduce the hardness of groundwater to the level of hardness that is allowed as group B water (clean water) based on membrane permeability consisting of rejection coefficient (% R) and membrane permeability. The permselectivity measurement is carried out by cross flow filtration for 15 minutes at a pressure variation of 0.5-2 bar. The results showed a membrane flux of 200-500 L / m2.hours, and a membrane permeability of 150-750 L/m2.hour.bar, the total hardness rejection coefficient (%RTotal) is 96.35%, the calcium hardness rejection coefficient (% RCa) obtained 95.99%, and the rejection coefficient of magnesium hardness (% RMg) is obtained 97.12% The permeability of the membrane is more selective against Mg ions (magnesium hardness) than Ca ions (calcium hardness). The best membrane composition is a mixture of 10% zeolite, 50% clay, 25% activated carbon, 10% white Portland cement and 5% PVA. [ABSTRACT FROM AUTHOR] |
