    Today, over-the-counter and prescription drugs have become a serious threat to our water systems. Ozone (O3) is a naturally occurring compound in the form of a gas that is a powerful oxidizer and strong disinfectant. 

  • Mazzei Degas Separators Selected For Wichita Aquifer Project
    Mazzei Degas Separators Selected For Wichita Aquifer Project

    The Mazzei GDT™ Degas Separator is a patented unit that utilizes centrifugal force to create a vortex enabling entrained gases to be extracted from water. The water-entrained gas mixture enters the top of the separator tangentially and flows through an accelerator plate, which increases velocity. The water spins down through the separator and exits the bottom. The entrained gas travels through the vortex where it passes into a collector and flows out the top of the separator. The separated gasses exit the separator through a degas relief valve.

    GDT Contacting Process… Transferring Ozone Into Solution Faster

    In the GDT™ process, high efficiency Mazzei® injectors aspirate ozone gas from a generator at 1-15% weight providing dynamic mixing and mass transfer. Dissolution is enhanced in a Flash Reactor™, determined for each application on the basis of feed gas concentration, operating pressure, reaction rates and desired transfer efficiency.

Only two liters of reagent are required for the analyzer to perform unattended for up to 90 days; twice as long as the Series 5000.

Pneumatic Dynamic Lifter Relief Valve Pneumatic Dynamic Lifter Relief Valve

The Pneumatic Dynamic Lifter is a very responsive compact wastewater relief valve that can handle high pressures and uses a compressed air cylinder to hold the valve closed. This chamber is fitted with a relief pilot that is normally closed as long as the line pressure is lower than the set point. If pressure rises above the set point, the relief pilot opens, causing the air in the cylinder to vent, which in turn opens the valve. The valve closes drip tight when pressure falls below the set point.

AERprocess AERprocess

Aerzen’s AERprocess Dissolved Oxygen Control is an integrated solution for controlling the dissolved oxygen (DO) concentration in the activated sludge treatment process and the blowers used to generate the process air flow requirement. The AERprocess system is able to maintain DO concentrations at their set points using a smart and efficient control strategy.
