RO Membranes
أغشية التناضح العكسي RO
Product Description
Because the membrane element controls output, recovery and water quality in any RO plant, DSTC matches RO membranes to the feed water, duty and existing vessel size. We support new plant selection, like-for-like replacement, and troubleshooting with cleaning chemicals, pressure vessels, cartridge filters, and spare parts.
For quotation, send membrane model, size 4040/8040, quantity, feed TDS, water analysis, plant capacity, application BWRO/SWRO, and delivery city.
Overview
The RO membrane is the core separation component in a reverse osmosis system. It affects salt rejection, permeate flow, operating pressure, energy use, and final water quality. Brackish water, well water, seawater, and high-fouling feed water require different membrane types. DSTC supplies RO membranes in Saudi Arabia and helps customers select the correct element based on water analysis, TDS, plant capacity, recovery, existing membrane model, and required product-water quality.

Frequently Asked Questions
Which RO membrane brands does DSTC supply?+
DSTC can supply leading RO membrane brands such as DuPont, Hydranautics, and LG Chem depending on stock, project requirement, and model availability.
What is the difference between brackish and seawater RO membranes?+
Brackish-water membranes are designed for lower salinity and lower pressure, while seawater membranes are designed for high salinity, high pressure, and higher salt rejection.
How much does an 8040 RO membrane cost in Saudi Arabia?+
The price depends on brand, model, membrane type, quantity, and stock availability. Send the model number or water analysis so DSTC can quote the correct element.
When should RO membranes be replaced?+
Membranes are replaced when normalized flow, salt rejection, or operating pressure remains outside acceptable limits even after proper cleaning.
Can DSTC match my existing membrane model?+
Yes. Share the current membrane model, quantity, vessel arrangement, and application so DSTC can recommend a matching or equivalent replacement.
