ABSTRACT:
An environmentally sound system for the removal of elemental phosphorus from waste water resulting from phosphorus manufacture, use, conversion to other products, and storage, wherein the waste water is treated with a material such as lime that produces an insoluble phosphate, filtering the precipitate and passing the filtrate through a column of an adsorbent, such as activated carbon, to produce elemental phosphorus-free water which can be discarded without deleterious effects to the environment.
