SWC6 MAX Hydranautics RO Membrane

Features

Datasheet Send enquiry

SWC6 membranes are the highest permeate flow membranes offering high energy efficiency. They are the membranes of choice when the seawater feed temperatures are lower that normally requires high feed pressures. SWC6 membranes result in lower feed pressures, lower energy consumption and lower treatment costs.

Delivering consistent high quality outputs at lower fouling, SWC6-LD membranes provide high flow and excellent salt rejections at low operating pressures.

SWC6-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 SWC6-LD membrane does not need to be cleaned frequently – thus reducing treatment cost – while offering extreme durability and consistent performance.

With an increased active surface area, SWC6 MAX offers significant cost and energy savings and uncompromised permeate quality in seawater desalination applications.

SWC6-LD membranes are available in 4.0 and 8.0 inch diameters and SWC6 MAX membranes in 8.0 inch diameters.
