Abstract
The rapid development of industrial areas around river areas affects pollution and raw water quality. As many as 2,7 million residents of Surabaya use the Kali Jagir Surabaya to supply their daily needs for bathing, washing and toilets even as a source of drinking water. The Surabaya river has the physical characteristic of blackish brown water which is an indication that the raw water has been polluted by waste. Slow sand filter technology is an effective alternative technology capable of treating water physically and biologically and has economic value and is environmentally friendly because there is no addition of chemicals to produce safe mud residue. The drawback of Slow Sand Filter technology is that in fluctuating river conditions, it will increase biomass, resulting in the schmutzdecke layer not growing optimally and clogging often occurring. In this research, the slow sand filter method uses a combination of geotextile media to overcome clogging with activated carbon which accelerates the permeability of processed water flow without reducing the efficiency of the slow sand filter. The aim of this research is to determine the optimization of the Slow Sand Filter in removing Permanganate and Total Coliform Values, the optimum time for schmutzdecke growth which influences the parameter removal and to determine the role of geotextiles in dealing with clogging and helping the growth of the schmutzdecke layer. In this study, there were 8 variations of filtration media used. With a downflow system, filtration speed of 0,1 m3/m2.hour and continuous flow for 8 days, sampling will be carried out every day to determine the most optimal removal level. The research results showed that the multi-media variation of silica sand, activated carbon and geotextile showed the best optimization in removing the Permanganate value of 81.48% and the multi-media variation of silica sand, activated carbon and layered geotextile showed the best optimization in removing Total Coliform of 64%. The use of Geotextiles in combination with Slow Sand Filter technology helps in dealing with clogging by making cleaning (scraping) easier and helping the growth of the schmutzdecke layer. The relationship between the growth time of the schmutzdecke layer and removal efficiency, the optimum time for removal of Permanganate Value is on the 8th day while the removal of the Total Coliform parameter is on the 7th day.
