Enhancing process reliability and increasing capacity are common issues facing water municipalities. On the one hand, community demographics are constantly evolving and water municipalities need to accommodate the impact to capacity requirements. At the same time, older systems that support pumping operations are not getting any younger and as control systems age, for example, it can become more time consuming to maintain equipment and more difficult to find replacement parts after systems have been in place for many years.

The key aspects to any process measurement and control of water is the quality and safety of the end product, in this case drinking water. There are three important factors that contribute to the quality of the product. Those factors are the performance of the measurement and control instrumentation, the long term reliability of the measurement and the inherent safety to the consumer.

Examples of “man versus nature” shifting towards “man and nature” are starting to emerge worldwide. Late 20th century theories on regenerative design, circular economies, natural capitalism, and biomimicry all speak to the goals of optimizing natural resources or services, minimizing waste, using nature as a model, and treating human settlements as integrated physical and natural systems.
Watch the video demonstration of Venturi injectors in use at Scott Laboratories.
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.
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.
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.
