Abstract: A system and method for cleaning of a forced-circulation evaporative crystallizer. The crystallizer is used to produce salt solids and includes a circulation pump, a heat exchanger, a separator, and a vapor processor. Solids deposits accumulate during salt solids production within at least one of the circulation pump, heat exchanger, and separator. A solids deposits metric representative of an amount of the accumulated solids deposits is measured. The solids deposits metric is determined to deviate from a baseline by at least a cleaning threshold. Certain determinations are made based on the solids deposits metric: determining a cleaning mode and at least one of a type of cleaning solution and a duration for which at least one of the circulation pump, heat exchanger, and separator is to be cleaned. At least one of the circulation pump, heat exchanger, and separator is then cleaned in accordance with those determinations.
