Benefits of disc diffuser:
> High oxygen transfer efficiency
> Low head loss value
> Slit geometry is developed via R&D activities
> Smooth membrane surface prevents the formation of bacterial plaque
> Surface structure enables the bubbles to easily leave the membrane
surface
> Small and intensive slit structure maximised oxygen transfer efficiency
Disc diffuser - applications:
> Wastewater treatments (WWT)
> Renaturation of lakes and rivers
