PPLICATION OF THE MODIFIED SORBENTS FOR IMPROVING EFFICIENCY OF PURIFICATION OF CHROMIC SEWAGE OF ELECTROPLATING INDUSTRIES

The object of research is chromic sewage of machine builders. The work objective ? is the develop- ment of technology of purification of chromic sewage with application of the modified natural sorbents with the improved sorption and mechanical properties. The structural features of the modified sorbents are investigated, and sorption properties of the above-named sorbents are studied. The suggested modified sorbent allows to reducing chrome to values of the maximum allowable concentration (MAC).
