R.O. vs. D.I. vs. Tap Water when mixing MWF
After attending a MWF seminar in 2000, I was convinced that D.I. water was the best type of water for mixing coolant. The shop was in the country, and there were many dissolved minerals not to mention 'hardness' in what came from the well. Today, I work in a shop that is in a city. The municipal water is used 'as-is' in order to mix coolant - A couple of questions: 1) Do different types of coolant (e.g. Water Soluble vs. Synthetic) require different water? 2) As the city looks after chorination, fluoridation, hardness, etc., is there no advantage left for Deionization? 3) In order to minimize waste, would D.I. be a better choice to mix MWF, compared agains Reverse Osmosis?

Well, water, water everywhere.
Dear Reader,
I'll address your questions one at a time:
1. The sort answer to question is "no." Your coolant supplier should be able to formulate a product that will work in the water you have in your plant. However, well water is the most troublesome since it will have consistency issues depending on weather conditions. That being said still your coolant supplier should be able to formulate around that problem.
2. If the city water is not causing you any problems then why go through the expense of buying a D. I. or RO unit?
3. I could devote a entire article to this question and I will so to answer this question, I will submit an article on the subject around the end of this week.
All the Best, Dom
