Elements composed of different packs of membranes, interspersed with special spacing nets, then rolled up on a plastic collector.
The system features an external fibreglass support for industrial processes or a special "rigid" network for health and food processes specially designed to prevent the collapse of the structure on itself.
Thanks to the radial component of the pressure part of the feed fluid permeates through the membrane while, due to the tangential component of the pressure, the "concentrate" not penetrated is pushed towards the exit of the membrane. This flow, parallel to the structure, therefore contains all the particles too large to cross the membrane thus allowing the self-cleaning of the membrane itself.
This type of membrane has numerous advantages including
