ABSTRACT:
The invention concerns a method of preparing brine by dissolving salt in water, the salt containing sodium chloride but also calcium sulfate and/or other soluble impurities with a slower dissolution rate than sodium chloride, wherein the salt is supplied to a vessel including a grid for supporting a salt bed, water is supplied and flows through and wets at least a portion of the salt bed before it flows through the grid, whereby small solid particles form and pass through the grid whereafter they are separated from the solution, said small particles containing essentially no sodium chloride.
The invention further concerns a device for making brine by dissolving salt in water, which device comprises a vessel containing a grid support, means for supplying solid salt, means for supplying water, means for the outflow of brine, and means for removing undissolved salt particles at the bottom of the vessel.
