Case Study: Electronic Forms Improve Patient Care And Save Money

Ozone is a powerful oxidizing agent that can be used to destroy the organic compounds that affect the taste and odor of potable water. Environmental concerns have led to increased use of ozone because, unlike chlorine, it does not form hazardous by-products.

Ozone is a powerful oxidant. Its effectiveness is measured by the amount of residual ozone remaining after disinfection. The presence of a small residual implies that all organic compounds have already been sterilized. Ozone use also increases the dissolved oxygen content of the stream that converts sulfides, sulfites, and nitrites to sulfates and nitrates leaving an insoluble easily removed surface scum.

The Rosemount Analytical Model 1056 Ozone analyzer and the Model 499A OZ Ozone Amperometric sensor can be used to monitor ozone residual in the contact chamber or in the treated water. The Model 499AOZ sensor is covered with a gas permeable membrane specific for ozone that eliminates interference from chlorine, bromine, peroxide, or their byproducts. The amperometric sensor develops a current that is directly proportional to the ozone residual. A minimum velocity of 1 ft/sec flowing past the sensor is required for accurate measurement. A Pt 100 RTD is embedded in the sensor for temperature compensation.
