To convert NaSO into other high-value products (NaOH, HSO, and (NH)SO), three types of cell configurations of electrodialysis (ED) were applied (three-compartment bipolar membrane ED (BMED), four-compartment ED metathesis (EDM) and five-compartment bipolar membrane ED multifunction (BMEDM)) and parameters such as average voltage variation, removal ratio of salt, product concentration, conversion rate, ion flux, and energy consumption were calculated and compared. The experimental results and calculations indicated that the overall performance of BMEDM was inferior to that of BMED and EDM. An industrial model was established, which indicated that the net profit from converting NaSO using BMEDM was always higher than that from BMED and EDM. Based on the advantages of low investment (132 $) and energy cost (152 $/t NaSO), EDM was applicable to factories with a low output of NaSO (production capacity <45%), whereas BMED (157.3 $/t NaSO) and BMED-5 (227.6 $/t NaSO) were applicable to factories with a high output of NaSO (production capacity >45%) based on high net profits.
为了将NaSO转化为其他高价值产品（NaOH、HSO和(NH)SO），应用了三种类型的电渗析（ED）电池配置（三室双极膜电渗析（BMED）、四室电渗析复分解（EDM）和五室双极膜电渗析多功能（BMEDM）），并计算和比较了平均电压变化、盐去除率、产物浓度、转化率、离子通量和能耗等参数。实验结果和计算表明，BMEDM的整体性能不如BMED和EDM。建立了一个工业模型，该模型表明使用BMEDM转化NaSO的净利润始终高于BMED和EDM。基于低投资（132美元）和能源成本（152美元/t NaSO）的优势，EDM适用于NaSO产量低（生产能力<45%）的工厂，而BMED（157.3美元/t NaSO）和BMED - 5（227.6美元/t NaSO）基于高净利润适用于NaSO产量高（生产能力>45%）的工厂。
