A stochastic method was used to study the variation of the initial filter coefficient. Through physical experiment, the collected data include the initial inflow and outflow concentration, the size distributions of particles in suspension and so on. By introducing the standard capture probability function P(d) and the characteristic length of filter bed L c , this separated the grains' and particles' influence on filter coefficient. An example showed that we could use P(d), L c to ascertain the result of effluent distribution, ratio of C out to C in in any depths and equivalent filter coefficient λ m . We also studied the filter coefficient λ l during the experiment and the first-order derivative of λ l .
