Product description
Brackish RO membrane is an energy-efficient and anti-pollution desalination solution specifically engineered to treat water with moderate salinity levels (1,000 – 8,000 ppm TDS) at relatively low pressures, making it suitable for a wide range of municipal, industrial, agricultural, and residential applications.
Product Features
- Modification technology
Multi membrane bag structure that pollutants are easily cleaned.
- Short process and wide flow channel
Widen flow channel, dirt blockage is easy to flush out, and low-frequency cleaning has a long service life.

Note:（1）Performance parameters are measured after 30 minutes of stable operation of the system;
（2）The deviation of water yield ranges from ±15%;
（3）The recommended temperature for chemical cleaning is ≤30°C, and the pH value of the cleaning solution should not exceed 2.0-12.0 when above this temperature.
