Ozone Injection

Transvac Liquid Jet Compressors have been extensively used for entraining ozone and atmospheric air in water treatment applications.

Using liquid as the motive force Transvac Jet Compressors can accurately entrain and mix air or gas in-line and discharge against a back pressure.

Principle of operation

In operation a high velocity jet of pressurised liquid discharged from the motive nozzle produces a region of low pressure in the suction chamber that entrains the secondary gas. The two streams then thoroughly mix in the throat before the resulting mixture flows through the diverging cone to regain some pressure in order to overcome system discharge heads.
