FIELD: chemical industry. SUBSTANCE: process for removing impurities from water by passing it through layer of graphite comprising, wt.-%: SiO, 96.80-10.00; 1.63-29-80; AlO, 0.87-25.20 metals (iron, calcium, magnesium, sodium, potassium, manganese, titanium) 0.70-35.00 with particle size of 0.30-4.00 mm at rate of 0.05-2.5 l/kg per hour. Sorbent is regenerated by treatment with water at 95-100 C, solid and liquid phase are separated, sorbent is dried and heated to 150-500 C. EFFECT: more efficiency purification process. 2 cl |
