Products Description
The Nano Ultra-Low Pressure RO Membrane utilizes nano-ion surface modification technology to reinforce the membrane layer and enhance surface hydrophilicity, resulting in faster water flux and reduced fouling adhesion. This improvement lowers the frequency of chemical cleaning and extends the membrane's service life by 10%–20%, offering a superior cost-performance ratio. Meanwhile, the membrane operates effectively under lower pressure conditions, demonstrating excellent energy-saving performance while maintaining a high salt rejection rate.
