Increase of purification capacity and the performance of slow filtering in the removal of bacteria in an activated carbon-soil-sand filter unit

Abstract Mini scale carbon-soil-sand filtering system can be highly effective on surface waters, without requiring the use of coagulation preceding filtration. It is effective in removing suspended solids, toxic metals and imposes a 98-99 % reduction in bacteria. A novel filtering system is describe...
