    hi
    there are two types of filter 1. slow sand filter 2. rapid sand or rapid gravity filter.
    slow sand filter has a rate of filtration of 100-200 l/hr/sq.m. and area reqd would be too large(100-2000sq.m). but for RSF rate of filtration is 30 times higher than SSF. the surface area reqd. is low (10 - 50 sq.m) . SSF ( bacterial removal is 98-99%)is good but in cities that is impossible because it takes so much of time , it can be adopted in small villages . water is required for lakhs of people in short time. so use of RSF is desirable.you can design rapid sand filter.
    Are you sure? This action cannot be undone.
