1) Technical Principles

Membrane-enrichment, WEM membrane depth-enhancement-mechanical vapor recompression (MVR) process, which uses nanofiltration and reverse osmosis for salt concentration, followed by WEM membrane enrichment, and finally MVR reactor evaporation. The use of a multi-step membrane process to concentrate and evaporate can reduce the MVR reactor load and investment and reduce operating costs.
