FIELD: sugar industry. SUBSTANCE: method involves addition of calcium hydroxide to the barometric water or condensate, water sulfitation and air bubbling through sulfitation water. Air contains ozone (12-18 g/m3), air consumption is 13-17 m3/h, its bubbling is carried out for 12-18 min for oxidation and mineralization of impurities in treating water. EFFECT: improved method of water preparation.
