Brackish Water(BW) RO Membrane Sheet

Brackish Water Membrane Sheet
Core positioning: The most versatile "medium desalination" membrane, designed for brackish water (TDS 1000~10000mg/L), balancing desalination rate, flux, and energy consumption.

Key features:
The desalination rate covers the medium to high range (95%~99.5%), and most mainstream products are above 98%, which can reduce the TDS of brackish water to less than 500mg/L;
It has medium salt concentration resistance and moderate operating pressure (1.0~3.0MPa). The material is mainly an aromatic polyamide composite membrane and has high cost-performance.
Scenario adaptation: desalination of high TDS groundwater in North China/Northwest China, pretreatment of industrial boiler feed water, and purification of island brackish water. It is the "standard membrane type" for commercial and household water purifiers.

Anti-Fouling Membrane Sheet
Core positioning: With "anti-pollution, long life" as the core, it is specially designed for highly polluted water sources to solve the problem of flux attenuation caused by membrane fouling.

Key features:
Surface modification is the core technology: reducing pollutant adsorption through hydrophilization (introduction of hydroxyl/carboxyl groups), low roughness (Ra≤5nm), and charge control (same electric repulsion).
The desalination rate is close to that of brackish water membrane (95%~99%), but the chemical stability is stronger (acid and alkali resistance pH 1~12), and the cleaning recovery rate after pollution can reach more than 95%.
The operating pressure is the same as that of the brackish water membrane, but the flow channel design is wider (≥0.8mm) to enhance the water flow scouring effect.
Scene adaptation: treatment and reuse of industrial wastewater (printing and dyeing, electroplating, chemical industry), high turbidity groundwater (containing sediment/colloid), algae-containing surface water purification, especially suitable for scenarios with incomplete pretreatment or large fluctuations in water quality.
