EVOLUTION OF DEVELOPMENT OF TECHNOLOGIES FOR BITTERN UTILIZATION IN CHINA
The composition and distribution of bittern from Chinese sea salt works were investigated. The process principle, technology flow, technical and economic index and . developing progress of the technologies of bittern complex utilization, including recovering potassium chloride from bittern by mixing brine method, preparing potassium sulfate using bittern and potassium chloride, extracting potassium sulfate using bittern and seawater by zeolite method were introduced in detail. The advantages and disadvantages of those kinds of technologies were discussed and the development trend of the new technologies of complex utilization of bittern was proposed.
