Filtration membranes are used extensively around the world in many industries and processes to remove particles on a molecular level.
Shrinking fresh water supplies and population growth continue to drive the need for sustainable solutions in water use. This drives industries to continue to look for ways to purify and re-use waste water and seek new, cost-effective methods of providing drinking water. Membranes have become an integral part of waste water treatment or drinking water systems for efficient separation.
Membranes meet the highest technical and hygienic standards. Therefore, 3M´s flat sheet and capillary membrane are used in pharmaceutical, biotechnology and many food and beverage applications. Membranes ensure the sterility of liquids used in making pharmaceuticals. In the food and beverage industry membrane is used for separation processes to ensure purificaction and product stability.
Manufacturing plants worldwide rely on the continual supply of purified water and liquids in their processes. The water used to manufacture many advanced microelectronics, such as semiconductor chips, are purified and filtered with our membranes.
Membranes act as semi-permeable barriers, which separate two media. Out of a mixture of multiple substances, target components are allowed to pass through this barrier while others are retained by the membrane, resulting in efficient, economical separation. The separation mechanism is based on either size exclusion or solution/dissolution effects.
Haemodialysis is a procedure to replace the excretory kidney function in case of severe renal insufficiency. In healthy humans, the kidney removes waste and toxins from the blood, which are then excreted via urine.
Oxygenation is a procedure to replace or support the breathing function of the lung. In cardiac surgery as well as in the treatment of lung failure oxygenators or artificial lungs breathe for the patient outside the human body.
In plasmapheresis, plasma is separated from the blood cells and either retained for the production of the therapeutic proteins or filtered and returned to the blood as a treatment for various autoimmune disorders.
Ultrafiltration for water treatment and microfiltration for beverage clarification are major application fields of our filtration modules. Ultrafiltration modules are commonly used in RO pre-treatment, water re-use, drinking water and other applications. Microfiltration modules are commonly used for the separation of suspended solids from wine or juice to improve clarity without impacting flavor components.
3M Membranes are used to make filter elements for separation processes is many industries. The broad range of hydrophilic and hydrophobic membranes in capillary or flat sheet configuration with different retention characteristics and excellent chemical compatibility making them first choice in ultrafiltration and microfiltration applications.
Dissolved gas control in liquids is critical to many industrial processes in order to reduce corrosion, improve process efficiency and decrease yield loss. Membrane contractors utilize microporous membrane hollow fiber to offer a reliable, modular solution for deaeration and adding gases to liquids.
