High Permeability and Low Pressure CTA Hollow Fiber Reverse Osmosis Membrane “HOLLOSEP^® HW”

Abstract

TOYOBO has developed a new CTA hollow fiber RO membrane product suitable for water reclamation by MBR + RO system, which has excellent features such as high permeability, low pressure, chlorine resistance and surfactant resistance.
Increasing asymmetry of membrane structure formation makes them possible to improve flux and solute rejections and to lower operational pressure. Both open-ended (B.O.E.) element design are applied to reduce the pressure loss in a RO lumen for large size modules.
A stable and sufficient performance of this new product was observed in the pilot testing of water reclamation from MBR treated sewage, using intermittent chlorine injection (ICI) method.
