A two stage trickling filter system in series is used to treat a waste water flow of 7575 mm with
a strength of 400m(g)/(L),BOD_(5) at 20\deg C. Each filter is to be 2.4t_(m) deep and operated at a recirculation
ratio of 4:1. An overall BOD_(5) removal efficiency of 90% is desired. For the most effective design, the
efficiency of the two filters should be approximately the same. Determine the volume of each titier.
