LFNano™ membrane elements come in 4” (10 cm) and 8” (20 cm) with six (6) different NF membranes to choose from. The 4” (10 cm) elements contain 3.4 m2 of membrane (37 ft2) and the 8” elements (20 cm) contain 17.7 m2 (190 ft2). All elements are one meter long (40”).
The six different NF membranes are shown in the table below. The varying removal of magnesium sulfate and sodium chloride are shown in the table.
