Hydranautics SWC4B Membrane

Quality parts at an exceptional value
Product Description

The SWC4B can meet your industrial and commercial seawater desalination standards. Hydranautics membrane formulations are designed to accommodate varying levels of seawater salinities worldwide with reliable field-proven performance. They have the highest boron rejection available. Hydranautics has over two decades of experience in desalination and over 1.7 million cubic meters (461 million gallons per day) of seawater treated by their SWC (seawater composite) membranes.
