Study of hard water pre-treatment methods for membrane purification

This paper describes hard water pre-treatment and mineralization for subsequent water conditioning, using membrane methods. Furthermore, we show that application of ion exchange water softening at its preliminary preparation stage is appropriate on the condition that water hardness is less than 20meq/dm3. Through experiments performed, we prove that the antiscalants usage is efficient for water pre-treatment with a high level of noncarbonated hardness.
