Pro-ULP Domestic RO Membrane – Ultra-Low Pressure High-Flux Solution for Drinking Water
PSI MEMBRANE® Pro-ULP Series Domestic RO Membrane is an ultra-low pressure domestic reverse osmosis membrane designed for residential drinking water purification and light commercial use.
This advanced domestic RO membrane delivers significantly higher water flux under ultra-low operating pressure, ensuring pure, safe, and great-tasting drinking water while reducing energy consumption.
Key Features & Benefits of Pro-ULP Domestic RO Membrane
1. 30% higher flux for domestic RO systems
The Pro-ULP domestic RO membrane enhances permeate flow by up to 30%, providing faster water production and improved efficiency in home RO water purifier systems.
2. Reliable performance with long-term cost efficiency
Engineered for durability, this domestic reverse osmosis membrane offers stable long-term operation with reduced maintenance and replacement frequency, delivering excellent cost-effectiveness for household users.
3. Stable operation across a wide TDS range
The Pro-ULP domestic RO membrane performs consistently across a wide range of feed water TDS levels, with slow flux decline and stable salt rejection. This makes it suitable for variable municipal water sources and mixed household water conditions.

General Handing Procedures
Store in a cool and dry place (below 45°C) away from sunlight.
Permeate from the first hour of operation should be discarded.
Keep elements moist at all times after initial wetting.
To prevent microbial growth in the Wet Membrane Element, it is recommended to wash it with a 1.0% Sodium Metabisulfite (food grade) solution, followed by vacuum-bag packing the
Membrane Element and storing it in a cardboard box.
Only use chemicals compatible with the membrane elements and components. Bright Star Water will not accept any responsibility for the use of incompatible chemicals.
