The Seair activities corresponds to work by other companies, including Spartan on oil field water treatment. Produced water is the water used in the extraction of oil from the ground. In some cases this water must be treated prior to discharge. Where their are limits on inorganic or organic contaminants, ozone water treatment has been shown to reduce the level of these compounds.
Fac water is used to fracture the geologic formations that hold water. Similarly, if this water needs to be discharged, it may need treatment to remove contaminants.
While these activities might be slowing down with the lower price of oil today, eventually a combination of higher demand for oil and greater limitations in the discharge of water used to extract oil will create a demand for new water treatment applications including the use of ozone water treatment.
