A bench scale RO process simulator was operated in a batch concentration mode to determine the effects of product water recovery and feed water temperature on flux, rejection, and inorganic fouling by gypsum scale formation for simulated brackish water. As feed water temperature increased, salt reje

The kinetic of precipitation of calcium sulfate dihydrate (gypsum) in sodium chloride solutions was investigated at various supersaturation from 1.05–2.49, pH = 8.50, 25°C and ionic strength 0.5 M. The rate of precipitation showed a quadratic dependence upon the relative supersaturation which sugges

Calcium sulfate dihydrate scale was electrochemically deposited from supersaturated solutions on gold electrodes (probe) of an electrochemical quartz crystal microbalance (QCM). From measurements of the induction period for the gypsum nucleation, the interfacial tension was calculated. The dependenc
