KC-BW-4021 Brackish Water RO Membrane Element for Compact Water Treatment Systems
KC-BW-4021 is a compact brackish water reverse osmosis membrane element developed for small-capacity RO systems requiring stable salt rejection, reliable permeate flow, and efficient operation. Based on aromatic polyamide technology, it provides dependable desalination performance under low-pressure brackish water operating conditions.
Designed for feed water TDS up to approximately 5,000 mg/L, KC-BW-4021 is suitable for brackish water, surface water, groundwater, and tap water treatment. Its compact structure makes it ideal for space-limited RO equipment, decentralized water treatment systems, and small industrial pure water applications.

FAQ
FAQ
Q1. How is KC-BW-4021 different from KC-BW 4040 Series membranes?
KC-BW-4021 is designed for smaller and more compact RO equipment, while KC-BW 4040 Series membranes are generally used in higher-capacity commercial, modular, and medium-sized industrial systems.
Q2. What feed water is suitable for KC-BW-4021?
KC-BW-4021 is typically used for brackish water, surface water, groundwater, and tap water treatment with feed water TDS up to approximately 5,000 mg/L, depending on pretreatment and system design.
Q3. Is KC-BW-4021 suitable for small industrial water treatment systems?
Yes. It can be used in small industrial pure water systems, auxiliary RO equipment, compact process water applications, and small commercial water purification systems.
Q4. What should be considered before selecting KC-BW-4021?
Feed water TDS, target permeate quality, required water output, installation space, operating pressure, system recovery, and pretreatment conditions should all be evaluated.
