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.
GE HL4021TF Nanofiltration Elements are used for water softening, color removal, and reduction of THM potential.
GE Osmonics Desal HL4021TF Nano Filtration elements feature a tape outerwrap and 28 mil feed spacers and is designed with male end connections.
