a nozzle for injecting a reagent into the reactor;

a dispersion member disposed below the nozzle, the dispersion member having a generally cone shape including a tip;

the tip of the dispersion member generally facing the nozzle such that when the nozzle injects the reagent into the reactor the reagent contacts the dispersion member and is dispersed into the reactor in a generally conical pattern; and

a reagent inlet operatively connected to the reagent dispersing member for directing the reagent into the nozzle.

14. The water treatment system of claim 13 wherein the reagent dispersing member includes a height adjusting mechanism for adjusting the distance between the nozzle and the dispersion member.
