Ozonation

Ozonation
Ozonation is a water treatment process that destroys bacteria and other microorganisms through an infusion of ozone, a gas produced by subjecting oxygen molecules to high electrical voltage.

Ozone Benefits
Ozonation is very effective for inactivating Cryptosporidium, bacteria and other naturally-occurring organisms. Ozonation also can reduce the formation of trihalomethanes (THMs), which result from the interaction of chlorine and naturally-occurring organic material in the source water. A preliminary engineering study for the utilization of ozonation as a primary disinfectant at the NTMWD Water Treatment Plants has been aurthorized by the NTMWD Board of Directors to meet the Texas Commission on Environmental Quality Stage 2 Disinfection Byproducts rules effective 2012.

The following links provide a brief summary and justification for utilizing ozonation.
