Abstract:
A method of purifying water comprising the steps of:generating ozone; combining said ozone with flowing water; introducing the combination of ozone and water into a fluid mixer having an inline static mixer including a static mixer housing defining a static mixer housing interior and at least one inline static mixer element in said static mixer housing interior; flowing the combination of ozone and water through said static mixer housing interior and past the at least one inline static mixer element; during flow of the combination of ozone and water past the at least one inline static mixer element, engaging the at least one inline static mixer element with the combination of ozone and water to provide substantially complete transverse mixture uniformity with minimal longitudinal mixing of the combination of ozone and water to create a substantially homogeneous mixture of water and ozone; during engagement of the at least one inline static mixer element by the combination of ozone and water, consuming at-least some of the ozone in the combination of ozone and water; after creation of said substantially homogeneous mixture of water and ozone by said fluid mixer, introducing said substantially homogeneous mixture of water and ozone into a confined flow path having an exit and further having a length sufficient to provide substantially complete decomposition of the ozone in the substantially homogeneous mixture of water and ozone; flowing the substantially homogeneous mixture of ozone and water through the confined flow path to provide substantially complete decomposition of the ozone in the substantially homogeneous mixture of water and ozone so that no ozone requiring off gas destruction exits from said confined flow path; and after substantially complete decomposition of the ozone in the homogenous mixture of water and ozone, causing the water thereof to pass through said exit.
