Polymem joins the SIEBEC Group
The SIEBEC Group takes a new step in its development by announcing the acquisition of Polymem, a Toulouse-based manufacturer of filtration membranes.
Polymem, a complementary expertise
Founded in Toulouse | France, Polymem specialises in the design and manufacture of hollow fibre membranes for water and industrial fluid filtration. Its technologies cover three levels of membrane filtration:
- Microfiltration: separation of fine particles and micro-organisms.
- Ultrafiltration: removal of colloids, bacteria and macromolecules.
- Nanofiltration: retention of divalent ions and organic molecules.
This expertise naturally complements the SIEBEC Group’s existing offer, historically focused on mechanical filtration and industrial fluid transfer.
