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
