MEMBRANE TECHNOLOGY

 

A membrane is a selective layer that allows certain components to pass while rejecting others. Membrane technology uses these selective layers for efficient separation without the need for phase transitions. The actual membrane is typically a thin film manufactured from polymers, metals, or ceramics. Membranes can operate with liquid or gaseous feed streams and can be either dense or porous.

 

Pressure-driven process

Membranes are manufactured in various geometries: flat sheets, spiral wound, capillary, and tubular. Separation by means of membranes requires concentration or pressure difference as the driving force. In pressure-driven water applications, membranes are categorized by pore size:

• Microfiltration with a pore size of 0.1 to 1 µm 
• Ultrafiltration with a pore size of 5 - 100 nm 
• Nanofiltration with a pore size of 1 - 5 nm

Reverse osmosis uses dense membranes without pores to desalinate seawater and produce potable water. In gas separation, membranes are used to separate oxygen from nitrogen or to improve natural gas quality by removing carbon dioxide.

 

Versatile technology

Membrane technology is used in a wide variety of processes, such as desalination, water purification, beer clarification, gas separation, and electrodialysis.

With X-Flow membranes, Pentair develops and manufactures the ideal membrane technology for every industry and filtration application.

 

 

We offer information pages on our website where you can find detailed information about polymeric membranes, hollow fiber membranes, tubular membranes, capillary membranes, fiber membranes, water filtration, membrane filtration and membrane separation.

ULTRAFILTRATION 

X-Flow’s hollow fiber ultrafiltration (UF) membranes, with a MWCO (Molecular Weight Cutt-off) of 150 to 200 kilodaltons (kDa), remove all fine silt, turbidity, bacteria and viruses, as well as chlorine-resistant organisms such as Cryptosporidium and Giardia.

 

Water treatment

Ultrafiltration membrane productivity is high, while pressure differences remain low. X-Flow’s UF membrane technology is used to produce potable water and process water, and is used in the pre-treatment process of large seawater reverse osmosis (SWRO) plants.

X-Flow ultrafiltration membrane technology has proven to be an excellent large-scale treatment method for surface water, the effluent of wastewater treatment plants, and groundwater projects with suspended solids levels of up to 100 to 200 mg/L.
