Antiscalants or scale inhibitors are products that are added to water to prevent scaling.
Scale is the precipitate formed on material surfaces in contact with water as a result of the precipitation of ions like insoluble salts. Some examples of scale are calcium carbonate, calcium sulphate, and calcium silicate, MAP (or struvite).
Scale inhibitors are surface-active charged polymers. As salts exceed their solubility level and begin to crystallise, the polymers interact. The structure for crystallisation is disrupted and the formation of scale is prevented. The particles of scale combined with the inhibitor will then be dispersed and remain in suspension.
Examples of scale inhibitors we can supply are different phosphonates and Baypureâ, a readily biodegradable antiscalant.
