Evaporation and Crystallization Systems




RDG evaporation and crystallization systems are suitable for applications when water or other solvents are required to be removed from a mixed element solution. Depending on the application, the benefit of a given system may be based on the recovery of the solvent or the concentration of the constituents in solution.


Evaporation systems are designed to concentrate the feed stock to a heavy solution or slurry for reduction of  its volume for further processing, use or disposal. When a final solid product or waste is desired an RDG crystallizer is required. RDG crystallizer systems are designed to concentrated or purify solids from a solution.


RDG has the expertise to design systems for a wide variety of applications and end product types.
