RO Membranes vs. RO Housings: What's the Difference?
| Product Type | Purpose | Key Specifications to Check |
| RO Membranes | Separate dissolved salts and other constituents from feed water through reverse osmosis. | Model number, membrane dimensions, permeate flow rate, salt rejection, and feed water conditions |
| RO Membrane Housings | Contain and seal membrane elements within a RO system. Also called RO pressure vessels. | Membrane diameter, element capacity, vessel length, pressure rating, port configuration, and material compatibility |
How to Choose the Right RO Membrane
When selecting a replacement reverse osmosis membrane, start with your existing system specifications and water treatment objectives.
- Size and compatibility: Match the membrane dimensions, configuration, and model to your RO system.
- Permeate flow rate: Check the rated water production capacity under the specified test conditions.
- Salt rejection: Compare the manufacturer's rated salt rejection with your required treated-water quality.
- Feed water quality: Consider total dissolved solids (TDS), temperature, pH, and other relevant water chemistry.
- Operating conditions: Verify the recommended pressure range and other operating limits for your application.
How to Choose the Right RO Membrane Housing
An RO membrane housing, or reverse osmosis pressure vessel, must accommodate the membrane elements and withstand the operating conditions of your system.
Before ordering, confirm these important details:
- Membrane diameter: Verify compatibility with your membrane elements, such as 4-inch or 8-inch formats where applicable.
- Element capacity: Confirm how many membrane elements the vessel accommodates.
- Vessel length: Match the housing length to your required element configuration.
- Pressure rating: Ensure the vessel is rated for your system's operating requirements.
- Ports and connections: Check connection sizes, locations, and configuration.
- Materials and seals: Confirm compatibility with your feed water, temperature, and operating environment.
