Ozone is piped as a dry gas to a concrete ozone contact chamber where it passes through fine bubble diffusers and is transferred to the water. Contactors usually have 2 to 4 stages, depending on the treatment objective. Compressors, heat exchangers, refrigerated dryers, and desiccant dryers are not used. Although LOX is more expensive to purchase, there can be significant savings on the capital, operational and maintenance costs. Based on my conversations, Ozone is currently enjoying widespread use.
Ozone is an alternative that seems to be the answer to a number of treatment concerns.
