Chlorine Dioxide is a powerful oxidizing agent used for disinfection of potable water, cooling towers, and food wash water. It is also widely used for the bleaching of pulp in paper mills. As a disinfectant, CIO2 has advantages over chlorine in that it does not react with ammonia and many organic compounds while proving more effective at controlling bacteria, spores, viruses, and cysts. It is particularly well suited for removing biofilms from the inside of piping systems.

ATI’s Model Q46H/65 Chlorine Dioxide Monitor provides an economical and reliable measurement system for monitoring and controlling ClO2 treatment systems. With a variety of outputs including 4-20 mA analog, PID control, three adjustable relays, and digital communications, the Q46H/65 is adaptable to any ClO2  application.

BOB and MARI Will Monitor Water Chemistry in the San Francisco Bay

Scientists have had nagging questions about how ocean acidification might be affecting the waters of the San Francisco Bay. But if you can't trust BOB and MARI with your research questions, who can you trust? That's BOB, the Bay Ocean Buoy and MARI, BOB's companion mooring for Marine Acidification Research Inquiry, of course. BOB and MARI are a bright yellow, five-foot tall buoy and its companion mooring, respectively. They are anchored near the Estuary and Ocean Science (EOS) Center of San Francisco State University (SFSU). SFSU researchers are collaborating with scientists from the University of California, Davis and other funders and partner organizations on the first long-term project to monitor carbon dioxide and ocean acidity in the San Francisco Bay.
