Product Details


ULP4040 RO membrane for tap water achieves exceptionally high desalination efficiency at lower operating pressures, effectively reducing energy consumption while maintaining a stable permeate flow rate The standard 4x40 size of reverse osmosis membranes is compatible with most membrane housings on the market, simplifying the installation and replacement processes. The ULP series RO membranes demonstrate exceptional adaptability across applications such as purified water production, boiler feedwater supply, and reclaimed water reuse. RO membrane for tap water represents one of the application areas in water treatment.

 

As China's largest manufacturing base for reverse osmosis membranes, we do not rely on imported raw materials and are therefore unaffected by fluctuations in international logistics. Our facility is equipped with a total of eight automated production lines: six are dedicated to manufacturing the 8040 model, with a daily output of 600 units; the remaining two are dedicated to the 4040 model, with a daily output of 300 units.

FAQ

 

Q1: What are the primary indicators for membrane cleaning or replacement?

A: System performance should be monitored for "normalized" flow rates. Chemical cleaning (CIP) is generally required when the normalized permeate flow drops by 10% or the pressure drop increases by 15%. If performance cannot be restored through cleaning, or if salt passage increases significantly, the elements should be replaced, typically every 2 to 3 years depending on feed water quality.

Q2: Do you support custom branding or private labeling?

A: Full OEM services are available for established distributors and system integrators. This includes customized nameplates, specialized packaging, and technical documentation tailored to specific regional or project requirements.

Q3: Can I directly replace the reverse osmosis membrane elements I was using from another brand? Will they be incompatible with my membrane housing?

A: Our reverse osmosis membrane elements are manufactured according to international standard dimensions. If you still have concerns, please send us a photo of your existing membrane elements, and we will help you check if they can be replaced.

Q4: Is the ULP4040 compatible with existing RO systems?

A: Yes. The ULP4040 follows international standard dimensions (4 inches in diameter and 40 inches in length), making it a direct drop-in replacement for any standard 4040 housing. However, it is recommended to verify that the system's high-pressure pump is adjustable to accommodate the lower operating pressure requirements of the ULP series.

Q5: How should I store the reverse osmosis membranes I bought if I'm not using them immediately?

A: Our reverse osmosis membranes are treated with a protective solution and vacuum-packed at the factory. Do not open the packaging before use. Store them according to the following requirements:
Temperature: Optimal 5~10℃, do not exceed 35℃, and prevent freezing.
Environment: Cool, dry, away from light, and well-ventilated.
Stacking: Do not stack the packaging boxes more than 5 layers high, and keep the cardboard boxes dry.
