I Gede Wenten
Les Village, District of Tejakula, Buleleng Bali, is one of the refugee camps for the affected community of eruption Mount Agung, since September 2017. With the number of refugees, the availability of clean water becomes something very crucial, especially for everyday needs such as drinking and cooking. Ultrafiltration (UF) technology is a solution to overcome the problem of availability of clean water. UF membranes can set aside iron (Fe3 +), colloid, germs, and all particulates causing turbidity in surface water sources while maintaining important minerals in it. The installed ultrafiltration unit is also equipped with an integrated module that combines several processes in one module. The integrated module is equipped with activated carbon at the initial stage to remove odors, organic substances, and free chlorine. ZnO nanoparticles function as anti-bacterial substances and disinfection stage. With the integrated ultrafiltration unit, clean water and decent drinking water can be produced at once. The installed UF membrane unit can be used to treat surface water, such as river water and well water, become clean water and worth drinking at once. This activity can help meet the needs of drinking water and clean water for disastrous people in refugee camps so that the community does not depend on tank tank cars.
Application of appropriate technology
To meet the needs of clean water, the community in refugee camps only relies on assistance and PDAM tank cars. The amount of water supplied for drinking and cooking needs is very much as the increase in the number of refugees from various affected areas of the Mount Agung eruption disaster. With the installed UF unit in refugee camps, surface water (such as rivers and wells) can be processed into water worth drinking and cooking, so that the community no longer depends on the PDAM tank car if there is a delay in shipping.
