scope:

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.

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

Purpose

The purpose of this standard is to provide a minimum set of requirements for ozone systems for the treatment of potable water, wastewater, reclaimed water, and storm water. This standard is intended to assist with the design, procurement, installation, and commissioning of ozone systems
