AWWA F120-18 Ozone Systems for Water

This standard describes the minimum requirements for ozone systems and equipment used to treat potable water, wastewater, reclaimed water, and storm water. This standard covers high concentration ozone generation equipment using discharge dielectrics and modular-type ozone generators fed from oxygen gas vaporized from a liquid oxygen (LOX) storage system. Equipment under this standard includes ozone generators with associated ancillary equipment, design considerations, and testing requirements. Both fine bubble diffusion and sidestream ozone dissolution systems are described in the standard. For ozone destruct systems, both thermal-catalytic and thermal systems are described. This standard can be referenced for design, procurement, installation, and commissioning of ozone systems equipment used in water treatment.
