METHOD OF OBTAINING DECONTAMINATED WITH OZONE BOTTLED WATER, AND DECONTAMINATED BOTTLED WATER Russian patent published in 2013 - IPC C02F1/78 C02F1/50 C02F101/12 C02F103/04 

FIELD: chemistry.

SUBSTANCE: inventions can be used in production of bottled drinking water from natural water. Method of water obtaining includes supply of water from tank for untreated water into buffer tank, pumping of ozone before buffer tank, bottling of ozonated water. Consumption of water is supported constant, with ozone being pumped with constant concentration. Water from tank for untreated water is supplied to buffer tank by means of pump, equipped with frequency variator, minimal working period for pump constituting 5 min, more preferably 10 min, and maximal non-working period constitutes 45 minutes, more preferably 20 min. Consumption of water, supplied by pump is set equal 105-110% of maximal pump consumption, used for filling buffer tank, with limit for time of presence of treated water in buffer tank being maximum 45 min. Before supplying water into buffer tank with ozone, it is passed through static mixer and at least 5 m long tube. Ozone concentration at water entry into buffer tank constitutes from 0.10 to 1.00 mg/l, more preferably from 0.20 to 0.60 mg/l.

EFFECT: decontaminated and bottled water, obtained by claimed method, contains less than 10 mcg/l of bromate, more preferably les than 5 mcg/l of bromate and contains less than 25 mcg/l acetaldehyde, more preferably less than 15 mcg/l of acetaldehyde.
