| Kiky,
Tell me some more about you demineraliser unit. Is it a mixed bed Cation (SAC) and Anion (SBA) unit? If so, how difficult do you find the regeneration process to be? What about the effluent discharge after regeneration. How do you deal with it? I imagine the handeling of strong acids and bases has it's own problems as well.
I think one of the advantages of a RO unit is the fact that it requires no handling of dangerous chemicals of monitoring of waste discharges.
