  • Do antiscalants control sparingly soluble salts in reverse osmosis membrane units?
  • Application of antiscalants to control sparingly soluble salts that deposit in reverse osmosis membrane units has become one of the most important and significant issues in reverse osmosis practice [ 1, 2, 3, 4 ].
  • 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 reduce membrane washing procedures in reverse osmosis desalination?
  • It has been revealed that the mentioned antiscalant provides the possibility to decrease the number of membrane washing procedures in the reverse osmosis desalination of real underground water (permeate recovery, 80%) from four times in a year (for the traditional antiscalants) to one time in 15 months at a dose of only 1.25 mg/dm 3.
  • What are RO membrane antiscalants?
  • RO systems create salt concentrated water streams that could produce scale or fouling. Veolia's RO membrane antiscalants are pretreatment programs designed to eliminate scale and reduce fouling in membranes systems, regardless of the feedwater source.
