SWC5-LD-4040 – Hydranautics RO Membrane

Features

Datasheet  Send enquiry

SWC5-LD membranes use patented Low Differential LD™ technology designed to minimize colloidal fouling. They use a patented 34 mil thickness feed spacer that prevents colloidal fouling and increases the effectiveness of membrane cleaning.

As a result, the SWC5-LD membrane does not need to be cleaned frequently – thus reducing treatment cost – while offering extreme durability and consistent performance.
