Magnetically enhanced and nonmagnetic cation-exchange resins were already compared. Counterions and organic matter affect exchange. Drinking-water findings do not prove selective calcium removal from our high-salinity brine.

Antiscalant destruction before gypsum precipitation and seed reuse are prior work. Experiments used 1 L model concentrates. The approximately 97% result is precipitation progress toward equilibrium, not water recovery or removal of all dissolved calcium. Three seed-reuse cycles do not establish long-term stability.

BGNDRF Well 2 water was tested with and without an electromagnetic field at four recovery endpoints. Carbonate and gypsum responses differed; higher recovery did not eliminate gypsum scaling. One experiment per endpoint is not four independent replicates at each endpoint. This is an EMF device, not magnetic adsorbent beads.
