Complete Series of Reverse Osmosis Membranes for Ultimate Desalination

RO Membrane

Complete Series of Reverse Osmosis Membranes for Ultimate Desalination

Product Description:

Reverse osmosis is a membrane separation operation that uses pressure difference to overcome osmotic pressure, separating solvent from the solution. Our complete RO Membrane series removes non-ionic contaminants with molecular weights under 200 Daltons and completely rejects molecules over 300 Daltons, including particles, colloids, and microorganisms. The membrane effectively prevents contaminants larger than 0.0001 microns from passing through, removing more than 90% of ionic contamination and effectively all particulates. The product line includes Seawater (SW), Fouling Resistant (FR), Low Pressure (LP), Ultra-Low Pressure (ULP), and Extra Low Pressure (XLP) series in sizes ranging from 2.5-inch to 8-inch.

Product Advantage:

• Complete Series Availability: Offers a full spectrum of series including SW, FR, LP, ULP, and XLP to match specific feed water salinities and pressure requirements.

• Comprehensive Specifications: Available in standard industry sizes such as 8040, 4040, 2540, and 4021.

• High Rejection Rates: Delivers stable rejection rates up to 99.85% (SW series) and 99.7% (FR/LP series), ensuring ultra-pure water production.

• Commercial & Industrial Use: Includes specialized commercial SWRO and ultra-low pressure elements for diverse applications.

• Customization Supported: OEM and ODM services are fully supported for specialized configurations.
