KC-XLP4040 & XLP4021 Low-Pressure RO Membranes
KC-XLP4040 and KC-XLP4021 are extra-low pressure reverse osmosis membrane elements developed for energy-efficient treatment of low-salinity water. Based on aromatic polyamide technology, they provide high permeate flow and reliable salt rejection while operating at significantly reduced pressure.
Designed for feed water with TDS up to 1,000 mg/L, these membrane elements help lower energy consumption and system operating costs. KC-XLP4040 is suitable for small to medium-sized RO systems, while KC-XLP4021 is ideal for compact equipment where installation space is limited.

FAQ
FAQ
Q1. How should I choose between KC-XLP4040 and KC-XLP4021?
Model selection mainly depends on required water output, installation space, and system configuration. KC-XLP4040 is generally preferred for small to medium RO systems, while KC-XLP4021 is better suited to compact equipment with limited installation space.
Q2. Which applications benefit most from extra-low pressure RO membranes?
Extra-low pressure membranes are commonly selected for municipal water, groundwater, surface water, bottled water production, and other low-salinity applications where reducing energy consumption is an important design objective.
Q3. Can KC-XLP4040 and KC-XLP4021 be used to replace existing RO membrane brands?
When membrane dimensions, operating pressure, and system design are compatible, both models can be evaluated as alternative solutions for equipment upgrades or supplier replacement.
Q4. Is customization available?
Customization is available for membrane performance and sheet structure based on system requirements.
