Demineralization of Water


I would like to know what chemicals you use for Demineralisation of water for a Powder Coating Branch, We demineralize to 120 but we are wanting to get it down to 30 if you could help that would be appreciated.

Thank you.

Don't use chemicals. You are trying to remove chemicals. If the water is down to 120 you have several choices - ion exchange, electrolytic membranes, and reverse osmosis. Since the water is relatively clean ion exchange would probably be the most efficient.

Reverse Osmosis is the best way to reduce this.
