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.

Regional Air Pollution Control Agency Tracks Dayton Air Quality

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. Specialists at RAPCA focus on six pollutants in their work: ozone, particulate matter (PM), carbon monoxide, sulfur dioxide, lead and nitrogen oxides.

A Look At Ohio EPA’s Extensive And Successful Air Monitoring Network

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.

First Environmental Monitoring System For Baltimore’s Inner Harbor

Baltimore’s Inner Harbor and the rivers that flow into it are important sources of water to Chesapeake Bay, popular recreation sites and the targets of an ambitious clean-up plan. But the city has for some time lacked an environmental monitoring system for tracking water quality in the harbor continuously. That is about to change, thanks to a collaboration between the U.S. Geological Survey (USGS) and Environmental Protection Agency (EPA). It will lead to the new installation of a suite of sensors that will provide the public and scientists with the first comprehensive, real time look at water quality in the harbor.
