Abstract
A liquid such as water is sequentially treated with an ozone containing gas in at least two steps. During the first step, the liquid is treated with a first ozone containing gas which contains ozone at a first concentration. During the second step, the liquid is treated with a second ozone containing gas which contains ozone at a second concentration that is higher than the first concentration.
Claims15
A method for treating a liquid with a gas containing ozone comprising the steps of:
- (a) passing air through an ozone generator at a first flow rate to produce air having a first concentration of ozone and introducing the air having the first concentration of ozone into the liquid;
- and,
- (b) subsequently passing air through the ozone generator at a second flow rate to produce air having a second concentration of ozone which is higher than the first concentration of ozone and introducing the air having the second concentration of ozone into the liquid.
A method for treating a liquid with a gas containing ozone comprising the steps of:
- (a) treating the liquid with a first ozone containing gas which contains ozone at a first concentration;
- and,
- (b) subsequently treating the liquid with a second ozone containing gas which contains ozone at a second concentration which is higher than the first concentration.
