Abstract

A gas infusion module system utilizing hollow fiber membranes is designed for the efficient dissolution of ozone into aqueous streams for disinfection purposes for water treatment, wastewater treatment, swimming pools and spas, bottled water production, aquaculture, food and beverage production, and the textile industry, while minimizing ozone loss to the atmosphere, reducing operational costs, and enhancing the overall effectiveness of ozone disinfection. The system includes microporous hollow fibers that facilitate high mass transfer efficiency of ozone into the liquid phase, achieving gas transfer efficiencies over 90% and dissolved ozone concentrations of hundreds of ppm. A groundwater bioremediation treatment device (e.g., for contaminated water environments) can use an in-situ oxygen curtain (iSOC) control valve for flowing dissolved gasses such as oxygen, hydrogen, carbon dioxide, propane, ammonia, and sulfur dioxide into groundwater to stimulate bacteria to consume contaminants in the water table, improving the durability of the groundwater bioremediation treatment device because it inhibits (e.g., prevents) corrosion of the valve components.
