RO Membranes
4" and 8" brackish water, low-energy, fouling-resistant and seawater RO membrane elements.
RO Components & Spares
Quick answerRO components are the parts of a reverse osmosis system that hold and connect the membranes: the RO membranes themselves, FRP membrane pressure vessels, and fittings such as adaptor kits, Victaulic couplings and thrust cones. Filtsap supplies 4" and 8" membranes and vessels for new plants and replacements.
RO Membrane Pressure Vessels
FRP side-port and end-port housings for 1–7 elements, rated 300–1200 psi.
Membrane Adaptor Kits
Interconnectors, adaptors and O-ring kits that seal the elements inside the vessel.
Victaulic Couplings
Grooved couplings for fast, leak-free connection of RO headers and permeate lines.
Membrane Vessel Accessories
End caps, heads, retaining rings, saddles and clamps for pressure vessels.

FAQs
How long do RO membranes last?
With good pre-treatment (5 µm cartridge, SDI below 3, no chlorine) and regular cleaning, industrial RO membranes typically last 2–5 years.
Do you supply replacement membranes for any brand of plant?
Yes. Standard 4" × 40" and 8" × 40" elements fit most industrial RO plants. Send your existing membrane model for an equivalent.
