• High permeate flux
  High permeate flux is achieved using membrane with exceptionally high permeability.

• Long operating life
  Hollow fiber membranes manufactured with Asahi Kasei's proprietary technology provide superb mechanical strength and chemical resistance. Membrane deterioration from chemicals or biolysis is not a concern with general use.

• Precise separation characteristics
  Membrane with sharp and uniform pore size distribution produces high quality water without adding coagulants.

• Applicable for raw water with high turbidity
  Direct treatment of high turbidity raw water is possible. This is due to the unique structure of the module which provides for easy discharge of solids, together with the highly efficient flux maintenance protocol of simultaneous reverse filtration and air scrubbing

Applications

• Various Water
  Treatment Processes Various water treatment processes (drinking water, process water for food and beverage plant, various cleaning water, etc.)

• Treatment of Sewage and Waste Water
  Treatment of sewage and wastewater (advanced treatment of sewage, recovery of industrial wastewater, treatment of landfill leachate)

• Pretreatment of RO and NF
  Pretreatment of RO/NF (desalination of sea water, UPW production process, etc.)

• Sea Water Purification
  Purification of Seawater (deep-layer ocean water, aquarium water, aqua-farming water)
  
  
• Condensate and Recycled Water Treatment
  Treatment of condensate and recycled water (boiler, heat exchanger, swimming pool, irrigation)

System Arrangement

AS/RF
Long term stability of permeate flux is achieved by simultaneous reverse filtration and air scrubbing.
