Advantages of multimedia versus cartridge filtration
The multimedia filter offers a three dimensional filtration versus single dimensional filtration of cartridge filtration. This means that a multimedia filter can remove particles much smaller than its actual gap based direct impaction with the edia. Additional high-pressurized vessel not required to force the captured particles off the filter media. This cost has to be added to the filter cartridge system. The multimedia filter has approximately 10000 times more filter area than the cartridge filters. An increase in the dirt holding capacity leads to a reduction in the backwash fluid. This reduction, over a period, relaes to a vast decrease in fluid loss and better recovery efficiencies. The capital cost of a sand filter plant is roughly five to seven times cheaper that a cartridge filter system. The operating costs of the multimedia sand filters are negligible at least the first five years In addition, the units can be manually overridden without affecting the process or its performance.
