The growing demand for the world’s water, in combination with more stringent water quality regulations, has placed unprecedented burdens on municipal water treatment facilities to provide the public with drinking water that is safe, reliable and aesthetically pleasing.
Among the technologies now in use for dealing with these challenges is the injection of ozone, air, oxygen and other gases into water streams for disinfection, oxidation and gas stripping. The Mazzei GDT™ process has proven to be extremely efficient in dynamically transferring gases into pressurized solution while removing unwanted entrained or undissolved gases. A GDT system typically includes sidestream injection, a Flash Reactor™, a degas separator and a degas relief valve.
In addition to its technological benefits, the GDT process features:
- A small footprint
- Low costs for capital, installation and operation
- Easy installation
- Non-fouling pressurized operation
- The ability to contain and treat off-gas
Depending on a project’s requirements, a GDT system is sometimes followed by a basin nozzle manifold, Pipeline Flash Reactor™ (PFR) or Pipeline Flash Reactor Plus (PFR+) to provide additional mixing and contacting.
Every system is unique and requires focused engineering and planning. Mazzei’s broad spectrum of equipment and experience allows for system development that is cost-effective, efficient, and application-specific. Mazzei uses in-house computational fluid dynamics (CFD) modeling to rescue facilities with design flaws as well as optimize designs for new facilities, assuring that the desired physical and chemical processes are achieved. While the equipment size and configuration may vary from one system to the next, all Mazzei systems maximize efficiency.
Whether it is ozonation for disinfection, ozone for water reuse, air stripping to remove contaminates, or another application, contact Mazzei and let one of our sales engineers help find the solution to your challenge.
