The review copy will be edited for publication and may also be revised as appropriate based on any comments received during the public comment period. Therefore, this copy is not suitable for continued utilization and is intended only for comment purposes.

Final publication of the standard may take several months. When it is available, a notice will be published in the official notice section of Journal - American Water Works Association. The standard becomes an effective AWWA standard on the first day of the month following such publication in Journal - American Water Works Association.

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 side stream ozone dissolution systems are described in the standard. For ozone destruct systems, both thermal-catalytic and thermal systems are described.
1.1.1 Systems and facilities not included in this standard. Ozone systems provided by the ozone system supplier per this standard do not include the following systems or facilities:
1. Interconnecting piping, electrical and control wiring, and conduits.
2. Structure or housing for the ozone system including normal and emergency HVAC systems.
3. Quenching agent storage and feed facilities.
4. Regulatory agency permits.

This is the first edition of this standard.
