Features
- This product is suitable to treat waste water with TDS from 250 to 1000 ppm
- High permeate flow and salt rejection under lowpressure
- Approximately half the operating pressure ofregular low-pressure composite membrane,
- Saltrejection rate of up to 99.5%
- Decreasing the cost for relevant facilities andoperating cost for the RO system
