Because these ions are multivalent, they’re preferentially removed by NF membrane layers. Actually, NF has been used for a variety of years for municipal softening, especially in Florida. The advantage of NF over an RO, the various other membrane layer modern technology that declines ions, is that NF has a higher flux price. This implies that fewer membrane aspects are needed and it runs at a reduced pump pressure extra pounds each square inch (psi) or bars consequently supplying cost savings in operating costs. The benefit of membrane modern technology in this application is that no chemicals are required to assist in the removal of solidity ions, whether soda lime for municipal conditioning or common salt (salt chloride) when it comes to regeneration of normal domestic water softeners. Sodium ion exchange, the conventional innovation for domestic water softening for greater than HALF A CENTURY, makes use of ion exchange material (in the salt form) that adsorbs solidity ions from water passing through a bed of such material, and also launches sodium ions in exchange.
