As per many authentic references, about 97 percent of the water in the world belongs to oceans and seas, whereas 3 percent is freshwater available as glaciers, ice caps, and waterbodies. While we strive to manage available lakes, rivers, and other inland water resources to meet present and future public needs, why not look to these saline water reservoirs as potential alternatives for sustainability?

In the recent decades, the market for the products of the industrial process industries has changed greatly. The manufacture of mass products has shifted to locations where raw materials are available economically. Competitive pressures have forced a swing to specialization as well as to an ability to adapt to customers desires. The systems are designed so that the economic data, such as raw material properties, raw material costs, batch sizes, are quickly integrated into the processes. An important consideration is the assurance and improvement of product quality.

The past few months have been highly eventful for California water watchers. In June, by a margin of 57 to 43 percent, California voters approved Proposition 68, a $4.1 billion parks and water bond that will provide approximately $1.3 billion for water-related projects across the state. Then in July, the California Water Commission approved $2.6 billion of funds authorized by Proposition 1, passed by the voters in 2014, to be used for eight new water storage projects. These developments reflect that California is taking a bold and multi-pronged approach to addressing its water needs, investing both in new large infrastructure projects and in more modest projects to improve the state’s existing resources and assets.

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.
Ozone is one of the most powerful commercially available oxidants and is commonly used for municipal water and wastewater treatment. In addition to its oxidizing capabilities, it is an environmentally-friendly method of treatment.
