Elucidation of dual-mode inhibition mechanism of a typical polymer-based antiscalant on Red seawater for thermal desalination at higher temperatures and higher concentration factors

Multi-effect distillation brine treatment by membrane distillation: Effect of antiscalant and antifoaming agents on membrane performance and scaling control

“…Thus, CaSO4 crystals having a needle shape were distorted/damaged, thereby leading to formation of smaller size CaSO4 crystals, which refers to crystal inhibition. Similar studies reported that concentration of antiscalant alters the morphology of crystals formed during scaling [50,51]. This morphology change is due to a modification of the antiscalant, which engages in growth sites and prevents the formation of the regular shaped crystals.…”

Use of Antiscalant Polymers in Industrial Cooling Circuits: Laboratory Local Inhibition Law Applied to the Modeling of a Pilot Plant Performance

“…Calcium and magnesium ions are the major components of scaling in different water sources. Several previous studies were focused on new experimental or modeling methodologies to rapidly evaluate the antiscaling potential of new additives under different application conditions, in order to provide more efficient technologies for scale control. , Among the many research groups working on the development of various antiscalants and their efficiencies for scale inhibition, some considered high concentrations of feed water and high temperatures on the inhibition mechanism and showed that a higher dose of antiscalant was required to inhibit the scale formation for the relatively higher concentration of seawater and at a higher temperature . Recently, green additives such as Bistorta officinalis extract were also tested as inhibitors for prevention of corrosion and scale formation problems in cooling water systems .…”

“…1,2 Among the many research groups working on the development of various antiscalants and their efficiencies for scale inhibition, some considered high concentrations of feed water and high temperatures on the inhibition mechanism and showed that a higher dose of antiscalant was required to inhibit the scale formation for the relatively higher concentration of seawater and at a higher temperature. 3 Recently, green additives such as Bistorta officinalis extract were also tested as inhibitors for prevention of corrosion and scale formation problems in cooling water systems. 4 The inhibition action of this extract is due to adsorption of insoluble Fe 2+ complexes over the steel surface and behaves as a mixed-type film-forming corrosion inhibitor and prevents scale formation.…”
