WATER PURIFICATION BY OZONE

In the last several years there has been an increasing demand for drinking water in bottles, cans, etc., around the world. This demand and market growth has drawn manufacturers' attention to the necessity for specialized filling techniques where product safety and integrity is of utmost importance. Water purification by ozone guarantees a very high product quality resulting in a long shelf life. Experience has indicated that a small dose of ozone, in the region of 0.3 mg/l to 0.5 mg/l, is sufficient to sanitize the product and the product packaging. After filling, the bottles are placed on stock for a few days to allow the ozone to decompose back oxygen and well below the detectable limit. After this period, the ozone will have oxidized the organic substances in the water and any microbial activity will have been reduced to a minimum.
