Abstract
An apparatus and method for dissolving a gas in a liquid comprising a long tube or conduit having an inlet connected to a source of gas and liquid mixed together under pressure and an outlet connected to a back pressure valve that maintains the pressure in the tube above the partial gas pressure necessary to ensure that the liquid is saturated with the dissolved gas. The invention is especially useful for purifying, sterilizing, and clarifying water in a pool, tank or pond with air as the dissolved gas. A primary purpose of the invention is to enhance oxidation.
