  • Patent number: 10245576
    Abstract: The magnetic polymer nanocomposite for removal of divalent heavy metal ions from water is magnetic nanocomposite having a core of magnetite (Fe3O4) in a shell of branched polyhydroxystyrene (BHPS), designated as Fe3O4@BHPS. The nanocomposite is synthesized by co-precipitation in alkali solution. Testing showed the nanocomposite reached 93% and 80% Pb(II) and Cd(II) adsorption, respectively, in 30 minutes, attaining equilibrium in 120 minutes. The maximum adsorption capacities of Pb(II) and Cd(II) at 298K were 186.2 and 125 mg/g, respectively. After adsorption, the nanocomposite with the heavy metal(s) adsorbed thereto was easily removed from aqueous solution by application of a magnetic field.

  • Patent number: 10214433
    Abstract: A System for brine treatment scaling control in a water treatment system is described. In the system, a concentrated brine stream influent may be treated in an electrodialysis-reversal process to produce a concentrated brine stream effluent and a lower salinity diluent water, which may be potable water effluent. The concentrated brine stream effluent may be processed in a brine treatment scaling control system that may have a mixing vessel and a membrane filter with the mixing vessel seeded with calcium sulfate. A lowered salinity brine stream effluent may be produced for return to the electrodialysis-reversal process to allow operation at greater overall recovery and an elevated concentrated brine stream may be produced.
