| Abstract: | The sulfate removal methods and the 1500 kg/h membrane-process sodium sulfate removal process were introduced. Problems occurred during running were summarized, i.e. the addition amount of sodium sulfite was bigger and its consumption was high, turbulence formed in sulfate setdement tank for refrigeration unit, bottom support components of the sulfate setdement tank collapsed, and the parameters of diluted brine feeding into membrane filtering system were unstable, such as free chlorine content, pH value and temperature. Solutions were proposed. |
