An active brine reconcentration system has been incorporated into the design of the University of Illinois half-acre salt gradient solar pond facility. An important feature of the system is its ability to keep precipitation from diluting the brine. Experimental data presented is in good agreement with a numerical simulation model of the evaporation process. The “film”-type evaporation process used in the system efficiently collects solar energy for evaporating water from brine. Parasitic electrical energy requirements for the evaporation system are 1.2 watts per square meter of evaporation surface area.
