  • What is an antiscalant in water purification?
  • An antiscalant is a chemical or pre-treatment chemical that prevents the formation of scale, or crystallized mineral salts, commonly used in water purification systems, pipelines and cooling tower applications. Antiscalants are also known as scale inhibitor agents.
  • Is polyacrylic acid an antiscalant?
  • In the present study, it is planned to synthesize polyacrylic acid for evaluation and characterization as antiscalant. As carbonate and sulphate of calcium are the major scales in cooling waters, thrust is to be given towards the performance of the scale inhibitor with respect to these scales.
  • What is a polymer based antiscalant?
  • Polymer-based AS are synthetic polymers that have functional groups like carboxylic acid groups, acrylic acid, sulfonic acid, and phosphonic acid groups. Common global suppliers of antiscalants include Kurita Water Industries, Avista, Nalco, and Veolia.
  • Can antiscalants be used in RO desalination systems?
  • Applications of antiscalants in RO desalination systems Various antiscalants have been developed and applied in water treatment industries, such as boiler water, cooling water, thermal desalination and membrane industries, to mitigate scaling ( Chaussemier et al., 2015; Darton, 2000; Hasson et al., 2011; Liu et al., 2019; Nowack, 2003 ).
