English[edit]

Noun[edit]

antiscalant (plural antiscalants)

  1. (chemistry) Material preventing or slowing scaling of a surface.
    • 2001, Siobhán Francesca E. Boerlage, Scaling and Particulate Fouling in Membrane Filtration Systems, page 15
      Antiscalants inhibit scaling by one or more of the following mechanisms: threshold effect which keeps scalant ions in solution, crystal distortion by absorbing onto the crystal surface at active sites preventing further growth, and finally by dispersancy where a surface charge is added onto the crystals so that they repel one another, reducing their ability to adhere to each other and equipment surfaces, hence, they remain in solution.
