Membrane filter cartridge for reverse osmosis
Pall Disc Tube™ PALL

The Pall Disc Tube™ Module System is a major advance in Reverse Osmosis technology. The patented fluid dynamics and construction of the disc membrane stack result in an open channel, unrestricted and fully turbulent feedwater system. This means that suspended solids carried in the feedwater cannot be trapped or easily settle out inside the membrane module. In frequent maintenance, cleaning of the membranes can be successfully achieved using a standard, built-in system. Round-the-clock reliability and product water quality are also guaranteed. These are achieved through Pall's adherence to the highest standards in components, materials, and methods of design and construction. Advantages of the Disc Tube Module System include:

* Minimization of membrane scaling and fouling. The system uses short feed flow paths, open channels and high-packing densities to minimize concentration polarization and physical flow impediments. Consequently, scaling and fouling are greatly reduced while high energy efficiency is maintained.
* Long membrane life. The combination of low membrane scaling and fouling, highly stable membranes, and the simple built-in cleaning system means that membrane life-expectancy is not normally limited by feedwater pollution. Useful membrane life of five years or more can be expected.
