Marmon Industrial Water LLC Lime Softeners

Softening can be achieved by adding lime in the form of limewater, Ca(OH)2, which, in a carbonatation reaction with CO2, forms calcium carbonate precipitate, reacts next with multivalent cations to remove carbonate hardness, then reacts with anions to replace the non-carbonate hardness due to multivalent cations with non-carbonate hardness due to calcium. The process requires recarbonation through the addition of carbon dioxide to lower the pH which is raised during the initial softening process. Graver customizes our Reactivator Clarifier design to accommodate cold lime or warm lime operation as required for TSS hardness, alkalinity and silica removal. Options for on-site erection depending on location and site access are also available.
