Method to increase the quantity of dissolved gas in a liquid and to maintain the increased quantity of dissolved gas in the liquid until utilized

摘要

A method for increasing the quantity of a gas, e.g., ozone, dissolved in a liquid, e.g., ultrapure deionized water, are provided. The gas to be dissolved is introduced to the liquid under pressure and the resulting admixture delivered to the end-use station under pressure. Once at the end-use station, the admixture including the liquid and dissolved gas is subjected to controlled dispensing to maintain a high concentration of gas in the dispensed admixture.
