This paper details how the addition of an acid water neutralizer (5.5-6 pH) as a pre-treatment step to the Reverse Osmosis system saved over $23,000/year in downstream operation expenses at a New Jersey manufacturing plant. The acid water neutralizer, with an investment of less than $7,000 and operational and labor costs of only $700/year, has a Return on Investment of less than three months. While not a solution for all systems with reverse osmosis and high acidity, discussing neutralization with a qualified vendor can save Electrodeionization and/or Service DI operational expenses.
What is really interesting about this paper is it shows how a simple acid water neutralizer, properly applied, can save a considerable amount of money on operating expenses.
Having been in the water treatment industry for two decades, I have seen the trend in the water treatment industry towards more and more complex water treatment technologies and discounting past knowledge as old-fashioned. Often lost is a true understanding of water chemistry by some current "industry experts" and the simple, economic solutions to water treatment problems.
