Ultrafiltration membranes, equipment and complete treatment chains

Ultrafiltration is a membrane technology process that allows clarification and disinfection of water in a single step. The pressurized water enters the module and the water produced (filtrate) passes through the membrane barrier.

The retained substances (retentat) are removed from the module continuously or periodically, depending on the system used.

The membrane wall acts as a filter for all particles larger than 10-20 nm (algae, parasites, bacteria, viruses, germs and organic molecules).

Ultrafiltration makes it possible to obtain water of constant quality even if the water to be treated varies greatly in quality and turbidity; It is used for the total removal of suspended solids (bacteria, parasites, viruses, organic molecules and colloids).

The use of membrane ultrafiltration makes it possible to avoid and limit the use of chemicals.

We offer you the guarantee of a stable and proven product and a simple implementation.

CHEMDOC Water Technologies also provides maintenance services for your ultra filtration units :
