Features

For potable water production, pre-treatment for SWRO, water recovery from waste water and sewage effluent. Asahi Kasei UNA-620AB UF Membrane provide reliable water quality using the latest technology at low cost.

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
