The H-Series proprietary thin-film nanofiltration membrane elements are characterized by an approximate molecular weight cut-off of 150-300 daltons for uncharged organic molecules. Divalent and multivalent ion rejection is dependent upon feed concentration and composition. HL Nanofiltration Elements are used for water softening, color removal, and reduction of THM potential. HL3308T Water Softening elements feature a tape outer wrap and 28 mil feed spacers. This element is designed with flush end connections.
Specifications are based on a 2,000 mg/L MgSO4 solution at 100 psig (690 kPa) net pressure, 77°F (25°C), pH 7.5, and 15% recovery, after 24 hours. Individual flux may vary +25%/-15%.
