CO₂ For pH Control And Re-Carbonation In Drinking Water Treatment

The City of Bloomington’s water purification plant has been operating since 1929. The lime-treated water has high pH which can cause scaling and can eventually clog the piping and filters in the plant. So, the plant needs to re-carbonate the water thereby lowering and stabilizing the pH. CO2 is an effective and safe chemical that offers treatment flexibility for a utility doing pH control.
