Slow sand filter design calculation
Webb26 dec. 2024 · Design slow sand filter beds from the following data: Population to be served= 60,000 nos Average rate of demand= 160 lpcd Rate of filtration= 150 liters/hr/m2 L:B = 2:1 Assume design discharge as twice the average flow and; Assume that one unit will be kept on standby. Solution: The average quantity of water to be treated = 60,000 x … WebbThe size of the filter The size of a slow sand filter is determined by several factors. For example: Population of 1000 with water consumption of 100 litres/capita day. Wastage can be assumed to be 30 per cent of production. Therefore – total dally production needs to …

WebbThe most desirable media size depends on the suspended solids characteristics as well as the effluent quality requirements and the specific filter design. In general, rapid sand filters use sand with an effective size of 0.35-0.60 mm (0.014-0.024 in.) and a maximum uniformity coefficient of 1.7.
