The C-Series family, a triacetate/diacetate blend, has a higher flux and better mechanical stability than standard cellulose acetate. C-Series elements offer an increased chlorine resistance compared to thin-film elements.
CK Nanofiltration Elements are used for water softening, color removal, and reduction of THM potential when chlorine is required.
