KC-ULP2540 & ULP2521 Low-Pressure RO Membranes

KC-ULP2540 and KC-ULP2521 are ultra-low pressure reverse osmosis membrane elements developed for compact and decentralized RO systems treating low-salinity water. Basé sur la technologie du polyamide aromatique, they provide stable permeate flow and reliable salt rejection under reduced operating pressure.

Designed for feed water with TDS up to 2,000 mg/L, these membrane elements help improve energy efficiency while supporting flexible system design. They are widely used in compact water treatment equipment, decentralized water supply systems, and small industrial RO applications.

FAQ

T1. How should I choose between KC-ULP2540 and KC-ULP2521?
Selection mainly depends on installation space, required water production, and overall system configuration. KC-ULP2540 is generally used for larger compact systems, while KC-ULP2521 is better suited to more space-limited equipment.

T2. Can these membrane elements replace existing RO membrane brands?
When membrane dimensions and operating conditions are compatible, they can be evaluated as alternative solutions for system upgrades or supplier replacement.

T3. Are KC-ULP2540 and KC-ULP2521 suitable for OEM equipment manufacturing?
Oui. Both models are widely integrated into customized RO equipment developed by OEM and ODM manufacturers.

T4. La personnalisation est-elle disponible?
La personnalisation est disponible pour les performances de la membrane et la structure de la feuille en fonction des exigences du système.
