XLP series of extremely low-pressure aromatic polyamide compound membrane elements can work under ultra-low pressure to reach as high permeate flow and salt rejection as regular low-pressure membrane elements can, and is applicable to desalination of surface water and underground water. It operates under approximately half the operating pressure of a regular low-pressure composite membrane and achieves a salt rejection rate of up to 99.0%, which can decrease the investment costs for such relevant facilities as pump, piping, and container, etc. and the operating cost for the RO system, thus increasing the economic efficiency. Being suitable for the desalination treatment of those water sources with low salinity not requiring high salt rejection such as surface water, underground water, tap water, and municipal water, which have a salt concentration lower than 1000 ppm, XLP series of membrane elements is particularly applicable to the second-pass desalination with two-pass RO system, and is mainly applied to numerous applications of various scales, such as pure water production, boiler water replenishment, foodstuff processing, and pharmaceutical production.

Vontron XLP11-4040 RO Membrane – Ultra Efficiency with High Rejection

n

The Vontron XLP11-4040 RO Membrane stands out as a reliable, high-efficiency reverse osmosis element. It combines excellent salt rejection with reduced energy consumption, making it ideal for commercial and industrial applications. Moreover, its design supports longevity and stable performance across variable feed water conditions.

n

Because water chemistry varies widely, you should always perform a full water analysis before installation. The analysis helps determine whether pre-treatment (e.g., softening, anti-scalant dosing, chlorine removal) is necessary to protect the Vontron XLP11-4040 RO Membrane from fouling and premature damage.

Installation & Maintenance Advice

n

Install the Vontron XLP11-4040 RO Membrane aligned with the flow direction. Always flush new membranes with low pressure before applying full operating pressure. Use chemical cleaning protocols as recommended by Vontron based on fouling type (e.g., acids for scaling, alkali for organic fouling). Regularly monitor differential pressure and permeate quality to schedule clean-in-place (CIP) cycles.
