Effective treatment plant design for pathogen removal relies on basically either rapid and slow sand filtration followed by chlorination or prechlorination followed by coagulation,sedimentation,rapid sand filtration,and postchlorination.Breakthrough of pathogens to the treated water during backwashing of filters in the treatment plants is a Slow Sand media water treatment filter is very old type water filtration but very effective water treatment system.In the slow sand filter ,water entering first through about 32 -36 inches of sand,then through a multi size layer of gravel (This layer is known as schmutzdecke,which is German for “dirty skin.”) before entering the under
