No one does seawater desalination better
As the world is facing freshwater scarcity, Hydranautics brings a range of SWC RO membranes to meet the demands of desalination industry. SWC membranes have improved the productivity and salt rejection for more than two decades while reducing their environmental impact. SWC membranes come in a range of innovative formulations depending on the level of seawater salinity required.
SWC membranes come in a range of innovative formulations suitable for varying degrees of seawater salinity. Each offers the highest productivity and salt rejection rates in the industry combined with the optimized flow, low fouling and low energy consumption.
This exceptional performance and consistency creates demand for SWC membranes in seawater desalination and high TDS industrial waste water treatment applications, including conventional and hybrid designs.
SWC4 are highest rejection membranes and are designed to treat varying levels of seawater salinities and produce low levels of permeate TDS. SWC4 is popularly used in the treatment of seawater and waters with high TDS.
SWC4-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 SWC4-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, SWC4 MAX provides exceptional salt and boron rejection for warm water applications.
SWC4-LD and SWC4 MAX membranes are available in diameters of 8.0 inches and SWC4 membranes are available in diameter of 16.0 inches.

SWC5 membranes are designed to provide optimum salt rejection and permeate flows. They are the membranes of choice when lower permeate TDS and lower feed pressures are needed. SWC5 membranes offer highest energy efficiency at lowest costs and are used in the mega desalination plants.
Delivering consistent high quality outputs at lower fouling, SWC5-LD provides high flow, and excellent salt and boron rejections at low operating pressures.
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.
With an increased active surface area, SWC5 MAX provides exceptional salt rejection and high energy efficiency.
SWC5-LD membranes are available in 4.0 and 8.0 inches, SWC5 MAX membranes in 8.0 inch and SWC5 membranes in 16 inch diameters.

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 8.0 inch diameters and SWC6 MAX membranes in 8.0 inch diameters.
