AWWA F120-18 PDF Download

The AWWA F120-18 standard provides comprehensive guidelines for the design, procurement, installation, and commissioning of ozone systems and equipment used in water treatment processes. The scope of this standard encompasses various applications, including potable water, wastewater, reclaimed water, and storm water treatment.

The standard primarily focuses on high-concentration ozone generation equipment that utilizes discharge dielectrics and modular-type ozone generators fed by oxygen gas obtained from a liquid oxygen (LOX) storage system. It outlines the minimum requirements for ozone generators, including their ancillary equipment, design considerations, and testing requirements.

Additionally, the standard covers two methods of ozone dissolution: fine bubble diffusion and sidestream ozone dissolution systems. It provides guidance on the design and implementation of these systems for effective ozone distribution in the water.

Moreover, the standard addresses ozone destruct systems, describing both thermal-catalytic and thermal methods. The requirements for these systems ensure the safe and efficient removal of ozone residuals to prevent any potential harm to personnel or the environment.
