3M Liqui-Flux Ultrafiltration

Industrial Filtration

3M produces a broad range of microporous flat sheet and capillary membranes for use in various industries.

Our capillary and flat sheet hydrophobic and hydrophilic membranes are made from a variety of materials, such as polyethersulfone and polypropylene, to meet highly diversified market requirements. 3M supplies these membranes to filtration module manufacturers or cartridge producers to incorporate into their final products.

Polyethersulfone (PES) Membrane Technology Platform
Our production technology and controls allow us to fabricate self-supporting PES membranes. By casting an asymmetrical pore structure using the SIPS process, 3M produces a reliable portfolio of microfiltration membrane products in MicroPES and DuraPES.

Polypropylene (PP) Membrane Technology Platform
PP hydrophobic polyolefin membranes are produced using a TIPS pro­cess. As a result of this sophisticated manufacturing procedure, 3M™ Flat Membrane MF-PP Series provide high porosity combined with uniform pore dis­tribution throughout the thickness of the membrane

Healthcare products

Technically speaking, this purification is a filtration process that needs a filter – a membrane. One can either use a membrane which is already present in the body and that is largely suitable for this purpose (peritoneal dialysis) or an artificial membrane in an extracorporeal procedure (haemodialysis).

Haemodialysis is often referred to as "renal replacement therapy". However, intermittent extracorporeal dialysis can only
 
    remove toxins
    remove excess water and electrolytes in order to achieve homeostasis

In particular endocrine functions, including blood pressure regulation, stimulation of red blood cell production (erythropoesis), and vitamin D metabolism can of course not be replaced by a filtration process. Therefore, the only true renal replacement remains kidney transplantation.
