KC-SW2521 Seawater RO Membrane
KC-SW2521 is an ultra-compact seawater reverse osmosis membrane element developed for low-flow desalination systems where space, portability, and flexible installation are key design requirements. Based on aromatic polyamide technology, it provides reliable salt rejection and stable freshwater production under high-pressure seawater operating conditions.
Designed for feed water with salinity above 10,000 mg/L, KC-SW2521 helps equipment manufacturers build compact desalination units for mobile, decentralized, and space-limited applications. It is widely used in portable RO systems, small marine freshwater units, emergency water supply equipment, and remote water treatment projects.

FAQ
FAQ
Q1. What makes KC-SW2521 suitable for ultra-compact desalination equipment?
KC-SW2521 is designed for low-flow RO systems where installation space is very limited, making it suitable for portable, mobile, and compact seawater desalination equipment.
Q2. How is SW2521 different from SW2540?
SW2521 is generally used for smaller and lower-flow desalination systems, while SW2540 is more suitable for compact marine, shipboard, and skid-mounted systems requiring higher water output.
Q3. Which applications commonly use KC-SW2521?
It is commonly used in portable desalination units, small marine freshwater systems, emergency water supply equipment, decentralized treatment systems, and pilot-scale seawater RO projects.
Q4. What should be considered before selecting SW2521?
Feed water salinity, required freshwater output, available installation space, operating pressure, and system recovery should all be evaluated during system design.
