Degas Separators

The degas separator, an integral component of the Mazzei GDT™ system, is a patented centrifugal vortex unit designed to separate entrained and stripped gases—such as ozone, chlorine, or methane—from water, based on the density difference between the gas and liquid. Its unique, compact design quickly and effectively separates entrained gases and requires far less space than traditional gas separators. It enables gas separation with pressure differentials of 5% or lower and at variable flows. The self-cleaning design significantly reduces maintenance and downtime, and it includes no moving parts that can wear out, break down, or require service.

In Mazzei degas separators, the water-entrained gas mixture enters the top of the separator tangentially, which causes it to spin. The water spins and flows down through the separator to the bottom where it is discharged. The entrained gases collect at the vortex where they pass through a collector and flow out the top of the separator. The separated gases exit the separator through a degas relief valve.
