KC-ULP4021 Ultra-Low Pressure RO Membrane Element for Compact RO Equipment
KC-ULP4021 is an ultra-low pressure reverse osmosis membrane element developed for compact RO equipment where space efficiency and reliable performance are essential. Based on aromatic polyamide technology, it provides stable permeate flow and consistent salt rejection under low operating pressure conditions.
Designed for feed water with TDS up to 2,000 mg/L, KC-ULP4021 helps equipment manufacturers optimize system layout while reducing energy consumption. It is widely used in compact water purification systems, decentralized water treatment, and portable RO equipment.

FAQ
FAQ
Q1. What should be considered before selecting this membrane?
Feed water quality, target permeate capacity, installation space, and operating pressure should all be evaluated during system design.
Q2. What types of water are commonly treated with KC-ULP4021?
It is designed for low-salinity feed water with TDS up to approximately 2,000 mg/L, including municipal water, groundwater, and treated surface water.
Q3. How should I choose between KC-ULP4021 and KC-ULP4040?
The choice mainly depends on available installation space, required water production, and overall system configuration. Both models use the same membrane technology but are intended for different equipment sizes.
Q4. Can KC-ULP4021 be used in OEM equipment manufacturing?
Yes. It is widely integrated into customized water purification equipment developed by OEM and ODM manufacturers.
