Product specifications
- The stated performance is initial data taken after 30 minutes of operation based on the following conditions: 2000 ppm NaCl, 225psi (15.5bar) 25℃, pH 7.5, 15% recovery.
- Permeate flow rate for individual elements may vary with tolerance within 15%.
Description
FR(fouling resistant) Brackish water membrane element is developed for brackish water desalination featuring low pressure operation, high product water output, high salt rejection,etc. Through special treatment on RO membrane surface, membrane becomes more hydrophilic, precipitation of foulant and salt deposits is reduced, therefore, the fouling resistant effect is achieved. It is widely used in desalination of surface water, ground water, tap water,etc where the TDS value is between 2,000 mg/L-5,000 mg/L. It is specially applied to the reclaimed water in large and medium enterprises and purification of industrial waste water containing small amount of organic foulant or high salinity industrial waste water, and purification of city effluent,etc.
