Hydranautics & Nitto’s experience in membrane technology spans five decades. Nitto committed to delivering innovative membrane technologies to meet the growing demand of the separation industry. The design and manufacture a broad spectrum of reverse osmosis, nano-filtration, ultrafiltration and microfiltration membranes in various configurations and chemistries.

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, Hydranautics SWC5-LD provides high flow, and excellent salt and boron rejections at low operating pressures.


  • High permeate flow
  • High salt rejection – 99.8% (99.7% minimum)
  • 92% boron rejection
  • Lowest biological and colloidal fouling
  • Greater tolerance to high pH cleanings
  • Lower energy consumption
