Abstract
the method of circulating industrial waters treatment from metallurgical works with high content of phosphates is considered. It includes treatment via reagent precipitation with alkalization and flocculant addition, filtration of residue on a press-filter, further purification of water on a filter with granular loading, purification from residual calcium on an ion-exchange filter, neutralization of softened water and its final desalting in the unit of reverse osmosis.
