Abstract


Efforts to create a filter alternative in an emergency is very necessary in order to meet the drinking water needs. Filter pottery is one alternative screening models are cheap and mobility, so it can be applied, however, the ability of pottery on filtering raw water into drinking water needs to explored.. This study tested the ability to pottery from a mixture of clay and fine rice husk with 0.001 mole added of silver nitrate and 0.0005 mole within the period of use. This study conducted in soil and water engineering laboratory, Universitas Padjadjaran, Environmental Laboratory Institute of Ecology Universitas Padjadjaran and Energy and Mineral Resources Laboratory, West Java Province. This study also conducted pore size analysis using Scanning electron microscope (SEM) in order to know the pore diameter and pore distribution formed from the ceramic pot filter. The faucal-coli analysis is performed as an indicator of filter quality generated from the ceramic pot filter. The results showed that added of silver nitrate to lower the flow rate of 0:35 l/h. The Increasing added of silver nitrate also showed an increase in water resulting residue 0:02. Increasing the number of used periods to decrease of silver nitrate residue 0001. The results show that ceramic pot filter can reduce the number of e-coli with significant amount. The size of the pores of ceramic pots formed shows a diameter smaller than the diameter of e-coli. There are still some cracks in the process of making ceramic pots, thereby reducing the ability of ceramic pot filters to reduce e-coli.

Keywords
