  • 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.
  • How does antiscalant work for a reverse osmosis water treatment application?
  • An antiscalant is a pretreatment injected into the feedwater before the feedwater enters the RO membranes. Its presence delays the reaction between calcium magnesium and bicarbonate. This results is scale not forming as the water is being purified by the RO.
  • 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 ).
  • Why are antiscalants added to boiler feedwater?
  • Antiscalants are added to boiler feedwater to prevent scale formation on heat transfer surfaces, piping, and other boiler components. Water treatment plants can use antiscalants to maintain filtration. Industrial cooling water systems are susceptible to scale formation due to high temperatures and concentrations of dissolved minerals.
