AQUADYN modules use a unique 0.025 micron polyacrylonitrile (PAN) hollow fiber membrane that is hydrophilic, low-fouling, high-flux, and double asymmetric. The double asymmetric property allows the membrane to reject bacteria, solids and turbidity more effectively due to a filtration layer inside and outside the hollow fiber.

AQUADYN modules are used for:
- Biological treatment plant effluent
- RO pretreatment
- Storm water treatment
- River water treatment for industrial use
- Cooling water
- Water filtration for the food & beverage industry
- Borehole water treatment
- Karst water filtration
- Drinking water filtration
