The GDT™ Process starts with the creation of ozone from an Ozone Generator. The ozone is then drawn into a Mazzei®Venturi Injector which provides dynamic mixing (a Back Pressure Control Valve adjusts injector outlet pressure optimizing ozone mass transfer in the system). Then mixing and contacting is enhanced in a Flash Reactor™. From there the two-phase flow travels to the Degas Separator (DS) & Relief Valve for additional mixing and entrained gas removal. And finally, the MTM Mixing Nozzles force dissolved ozone flow into the untreated water in the pipeline or basin for thorough mixing.

As with so many other drinking water treatment processes, corrosion control demands a delicate balance among multiple factors. From the water-purifying chlorine that increases corrosion risk, to alternative strategies that reduce corrosion — using either elevated pH or phosphates — keeping corrosion under control requires sound strategy and reliable execution. Here are several approaches to addressing those conditions, along with options for better, more effective corrosion control.
This articles provides some fundamental tips and tricks to preparative chromatography that will yield a pure sample preparation that will advance protein characterization studies.
Angelo Mazzei has always thought locally and acted globally. Born and raised in California’s San Joaquin Valley — one of the world’s most productive farming regions — Angelo worked for his uncle’s 10,000-acre farming operation after graduating from college. There he saw a pressing need for a system that would allow farmers to safely and efficiently inject fertilizer into their irrigation water — a task made even more challenging with the 1968 introduction of high-pressure water supplies through the California Aqueduct, a 400-mile-long water conveyance system. A new approach was vital.
