Dissolved gas flotation (DGF) systems are used for a variety of applications throughout the world.
The method in which the bubbles are introduced into the water stream and retention time are also important factors.
As the impeller draws in the vapor it is mixed with the liquid being pumped and compressed into micro-fine bubbles.
The result of this process provides similar size bubbles to a dissolved air flotation system.
The backpressure valve on the discharge piping can regulate the bubble size in a DGF pump.
