How big is the filter tank for 1 hours to filter 5 tons of water?
The general height is taken as an empirical value 1800mm.
So the filter area is S=5/8=0.625m2, that is the filter radius =450mm.
The general sand filtration rate is 8m/h, so 5m3/h=S*8
Filtration water = filter area * filtration velocity
