  • What types of antiscalants are used in water treatment?
  • Antiscalant Selection Three types of antiscalants based on the chemical composition are used in the water treatment practice: polyphosphates, organophosphonates and other polymeric compounds. Polyphosphates include some of the original scale inhibitors used to prevent calcium carbonate scales and are primarily used in once-through systems.
  • What are antiscalants used for?
  • Antiscalant Antiscalants (scale inhibitors) are used in drinking water and process industry to prevent scaling or scale deposits on the membrane surface in a membrane-operated water treatment plant.
  • 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 ).
  • Can antiscalants be used for membrane scaling control?
  • Among these methods, the addition of antiscalants is a relatively cost-effective and convenient technique for membrane scaling control. In the current work, various kinds of antiscalants, scale inhibition mechanisms, and their applications to RO membrane scaling control are reviewed.
