Abstract

The present invention relates to a polymeric microporous diffuser which may or may not be inserted inside a pressure concentrator, in addition to being used in series in an air pressure distributor. Therefore, the invention could belong to the field of water treatment, in particular for introducing air for the treatment or movement of fluids or other activities requiring air in a water treatment system.
