Kinerja Filter Portabel Tepat Guna dalam Mereduksi Kekeruhan Air Banjir untuk Sanitasi atau MCK
During flood people had difficulties in obtaining clean water for sanitation (toilet). There was plenty of flood water but highly turbid. The water filter required electricity but its power outaged during flood. Filters usually used energy from electricity or gravity. This study evaluated the performance of a new handy-manually operated flood water portable filter. The standard of Permenkes No. 32/2017 was used as a reference. The flood water filter was pressurized by 0.025 kgf/cm2 and 0.051 kgf/cm2 and used local media: gravel, silica sand, anthracite, sponge. The results showed that pressure 0.025 kgf/cm2 was able to reduce turbidity from 220 NTU to 20.17 NTU with efficiency 90.83%. At 0.051 kgf/cm2 the filter was able to reduce turbidity from 220 NTU to 29.67 NTU with efficiency 86.52%. The pressure variation significantly affects the filtrate quality. The filter with pressure 0.025 kgf/cm2 could be applied for optimal filtration and produced 100-150 liters before clogging. This filter still needs to be studied related to physical strength, type and composition of media, portability and volume of water produced. This flood water filter will be an alternative solution for areas that often flood but no electricity or the power outage during flood.
