- How Much Does It Cost to Buy, Maintain, and Dispose of Ion Exchange Resins?
Below is a quick snapshot of the main types of ion exchange resins and their estimated costs: Weak Acid Cation (WAC) resins are a cost-effective choice for dealkalization applications where the feed water has a high proportion of hardness to alkalinity The WAC resin accomplishes this by removing divalent cations (e g calcium) and
