Oxy Injector-Ventoxal

The Oxy Injector-Ventoxal is designed for highly polluted process and wastewater streams.

A dynamic gas-injection device designed by Air Liquide, the Oxy Injector-Ventoxal system significantly increases the mass-transfer rate to reach high oxygen dissolution, and it integrates seamlessly with all types of wastewater basins.

The water that needs to be treated is pumped through a gas-liquid nozzle where oxygen is introduced. Emerging gas bubbles burst quickly, resulting in a highly dispersed fine-bubble stream. The oxygen-enriched fluid is then injected, thus enhancing overall oxygenation and mixing. During process steps where no oxygen is needed, the system provides the required mixing energy (e.g. for the denitrification step, the Oxy Injector-Ventoxal is able to mix the basin without gas injection).

The system can be adapted to wastewater basins with varying water depths and levels of pollution. The combination of mixing and high oxygen transfer makes it a powerfully effective solution.
