ABSTRACT:
Heterogenous nucleation on a seed material is promoted in the removal of phosphate from water by contacting the water with the seed material in a bed of grains of the seed material which bed is fluidized and kept in fluidization by the water stream itself, while the introduction of the reagent or reagents is effected so as to have a substantially complete heterogenous nucleation take place on the seed material.
