Membrane Water Softening and Desalination Datasheet

Membrane technology
Membrane technology allows the rejection of anything down to simple ions such as Na+ and Cl-. A number of treatment applications are therefore possible in the municipal and industrial water fields.

Water softening
Water softening (e.g. hardness and sulphate removal) using membrane filtration processes represents an interesting treatment application for improving the quality of fresh water. Water containing high amounts of sulphates or calcium can be satisfactorily treated thanks to the very fine porous structure of the membrane, which, depending on the chosen pore size (smaller pores require a higher applied pressure), allows a 94% to 99% rejection.
