FIELD: ecology and environment control; utilization of waste products of galvanic process; mechanical engineering; metallurgy, mining, chemical and pharmaceutical industries.
SUBSTANCE: proposed method of reworking waste solutions of galvanic processes into anhydrous product includes treatment of solutions by dry composition containing calcium oxide in the amount of 300-400 g/l; in reworking waste solutions containing polyvalent "p" or "d" metal, treatment is carried out by composition containing additionally aluminum sulfate whose mole fraction ranges from 0.1 to 0.15; total amount of polyvalent "p" or "d" metal is no less than 0.35 mole/l with aluminum content in composition taken into account.
EFFECT: possibility of obtaining anhydrous product and avoidance of forming of liquid effluents at utilization of various waste solutions.
