Hydranautics RO Membranes
ForeverPure Place distributes Hydranautics reverse osmosis and nanofiltration membranes manufactured by Nitto Denko. Hydranautics is a world leader in RO membrane technology with product lines covering seawater desalination, brackish water treatment, tap water purification, and specialty separation applications.
Hydranautics Membrane Series
Hydranautics SWC — Seawater RO Membranes
The SWC series delivers high NaCl rejection (99.6–99.8%) at seawater pressures for SWRO desalination. Available in standard and high-flow variants for different system configurations and energy targets.
Hydranautics ESPA — Energy-Saving Pressure Applications
ESPA membranes achieve high brackish water rejection at lower operating pressures, reducing pump energy requirements. The ESPA series is popular in commercial and municipal RO systems where energy efficiency is a priority.
Hydranautics CPA — Composite Polyamide
CPA high-rejection brackish water membranes provide the highest salt rejection available in low-energy brackish water elements. Ideal for applications requiring permeate TDS below 50 ppm from moderate-TDS feed water.
Hydranautics ESNA — Nanofiltration Membranes
ESNA nanofiltration membranes soften water and remove multivalent ions at lower pressures than standard RO, making them ideal for surface water softening, color removal, and partial desalination applications.
