KC-SW4040 Seawater RO Membrane Element for Modular and Commercial Desalination Systems
KC-SW4040 is a seawater reverse osmosis membrane element developed for compact and medium-capacity desalination systems treating high-salinity water. Based on aromatic polyamide technology, it delivers reliable salt rejection and stable permeate flow under high-pressure operating conditions.
Designed for feed water with salinity above 10,000 mg/L, KC-SW4040 helps equipment manufacturers and system integrators build efficient desalination systems with a compact footprint. It is widely used in commercial, industrial, and modular seawater treatment applications.

FAQ
FAQ
Q1. When is a 4040 seawater membrane preferred over an 8040 element?
A 4040 membrane is commonly selected for compact and medium-capacity desalination systems where installation space, equipment size, or project scale does not require 8040 elements.
Q2. What types of equipment typically use KC-SW4040?
KC-SW4040 is widely used in modular desalination units, commercial RO equipment, marine water treatment systems, and small to medium-sized industrial desalination projects.
Q3. What should be considered before selecting KC-SW4040?
Key considerations include feed water salinity, target water production, available installation space, operating pressure, and overall system configuration.
Q4. Can KC-SW4040 be used in membrane replacement projects?
Yes. When membrane dimensions and operating conditions are compatible, it can be evaluated as an alternative for equipment upgrades or supplier replacement.
