MVR salt production process flow
Pretreatment: Seawater or brine is first pretreated to remove impurities and adjust the concentration to a level suitable for evaporation.
Evaporation: The pretreated brine is sent to the evaporator, heated and evaporated at low pressure to produce steam and concentrated liquid.
Steam recompression: The secondary steam produced is compressed by the compressor to increase its pressure and temperature, and then returned to the evaporator as a heating medium.
Crystallization and separation: As the brine continues to evaporate and concentrate, the salt begins to crystallize. The crystallized salt is separated from the remaining liquid by filtration or centrifugation.
Drying and packaging: The separated salt crystals are further dried and then packaged for sale or storage.
