Our company specializes in manufacturing high-quality reverse osmosis (RO) and nanofiltration (NF) membrane elements, serving a wide range of applications including industrial brackish water desalination, seawater desalination, municipal wastewater treatment, food & beverage processing, pharmaceutical production, and household water purification. Our product lines include the XULP (extra low pressure), ULP (ultra low pressure), BW (brackish water), FR (anti-fouling), SW (seawater), and NF series. Utilizing advanced polyamide thin-film composite technology, our membranes deliver high desalination rates, low energy consumption, excellent anti-fouling properties, and long service life. We offer standard 4-inch and 8-inch industrial elements with OEM and customization services available.

1.High Desalination Rate
Industrial membranes achieve up to 99.7% stable rejection; household models ≥95%, ensuring superior product water quality
2.Ultra-Low Energy Consumption
XULP/ULP series operate at as low as 100-150 psi, significantly reducing electricity and operating costs
3.High Flow Capacity
8-inch industrial elements produce up to 12,500 GPD; household models offer 50-600 GPD
4.Anti-Fouling Design
FR series features fouling-resistant technology, ideal for wastewater reuse with high TOC/COD
5.Wide Operating Range
Temperature resistance -30℃ to 110℃, pH range 2-11; seal materials available in NBR/FPM/Viton
6.Full Size Compatibility
Complete range from 2.5" to 8" diameters; direct drop-in replacement for major brands
