Technical and economic analysis of “zero emission” treatment of  high salinity wastewater from coalfired power plants

Abstract

Abstract:

In a power station，wastewater dealt with the cascade utilization and enrichment， produces 50m3/h, high salinity waste water. Terminal wastewater, which come from deep concentrated high salinity waste water, will evaporate , crystallize and finally achieve zero emissions of wastewater. There is introductions about concentration technologies such as the disctube reverse osmosis, electrodialysis, positive osmosis, decumbent membrane steaming, and mechanical vapor compression (MVC), and evaporation crystallization process such as multiple effect distillation (MED), mechanical vapor recompression (MVR) and mechanical vapor compression (MVC). It provides the basis for choosing ideal treatment process to achieve the zero emission of high salinity waste water from coalfired power plant.
