ATI's Model Q46H/64 Dissolved Ozone Analyzer is the ideal choice for on-line monitoring and control of ozonation systems.
Water treatment processes using ozone gas have steadily increased over the past 20 years. Ozone has proven to be an extremely effective oxidant and is used to remove organic carbon from raw water and destroy most pathogens present. As a result, ozone treatment is now widely used in the semi-conductor, pharmaceutical, and food and beverage industries. In addition, many large cities now use ozone as an alternative to chlorine to improve the quality of the water distributed to their customers. This is because ozone is more effective against bacteria and viruses than chlorine.
ATI's Q46H/64 Dissolved Ozone Monitor provides an economical and reliable measurement system for monitoring and controlling ozone treatment systems. The Q46H/64 ozone monitor is adaptable to any ozone application as it has a variety of outputs including 4-20 mA analog, PID control, three adjustable relays, and digital communications.
The Q46H/64 ozone monitor uses a polarographic membraned sensor to accurately measure ozone in water. The sensor operates much like a battery, generating a current that is linearly proportional to the concentration of ozone in solution. An ozone-permeable membrane isolates the sensor from the measured sample and ensures that the measurement is interference free.

Across the Buckeye state, the Ohio Environmental Protection Agency works with district offices, health departments and contract agencies to monitor the state’s air quality. Monitoring approaches in each area is overseen by the Ohio EPA’s partner there.
In Dayton, Ohio, the partner in charge of monitoring air quality for the Ohio EPA is the Regional Air Pollution Control Agency (RAPCA), which oversees 11 sites in five counties surrounding the city. The Environmental Monitor recently visited a few of RAPCA’s monitoring sites to see how the agency carries out its mission and to get an update on issues affecting the city’s air quality.Read More
Since the passage of the Clean Air Act in 1970, Ohio has made significant strides in achieving good air quality. Part of the cleaner air the state now enjoys comes from shifts in manufacturing practices and the choices people have made to drive more fuel-efficient cars. But all of the achievements are owed in part to air monitoring efforts that have allowed environmental officials to track progress.
As part of its air quality maintenance work, the Ohio Environmental Protection Agency works with district offices, contract agencies and health departments around the state to oversee monitoring stations that keep track of six key pollutants: carbon monoxide, lead, nitrogen dioxide, ozone, particulate matter and sulfur dioxide.Read More
Growing from a 38-acre purchase in 1998 to 298 acres in 2004 to the 305 acres it encompasses today; the Black Fork River Wetlands features habitats not found just anywhere, including buttonbush swamp, swamp forest, marsh, riparian corridor and uplands habitats. Beavers make their homes there, as well as trumpeter swans, bald eagles, soras and sandhill cranes.
While it may seem picturesque and undisturbed, it is in fact embattled due to human activity on all sides. “It’s a multi-use area,” says Jenna Binder, a visiting Assistant Professor in Ashland University’s Biology and Toxicology Department. “It’s strongly influenced by the heavy agriculture in this area of Ohio. Oil and gas industry fracking is also being done in the area.Read More
