采用新开发的浓缩技术对闪蒸废盐水进行了浓缩研究。结果表明，浓盐水中NaCl浓度为264（g/l），纯度为96（%）（NaCl/T），耗电量为96（%）（NaCl/ T）。盐）和238（KWH/t-NaCl）。根据以下设计基准，安装成本为33.8亿日元，包括摊销在内的浓盐水总成本为2,760日元/吨NaCl。废卤量10万（m2/D），生产能力61万（t-NaCl/年），电流密度7（A/dm*），电5（YEN/KWH），回收盐的装置费用和操作费用大大降低，因此电渗析浓缩工艺比以往工业使用或生产食盐更有吸引力。
Concentration of waste brine exhausted from flash evaporator was studied with a newly developed, concentration technique. The results were that concentration of NaCl in concentrated brine, its purity, electric power consumption and its cost, respectively, were 264(g/l), 96(%)(NaCl/ T. salts) and 238(KWH/t-NaCl). Installation cost was 3,380 million YEN and total concentrated brine cost including amortization was 2,760(YEN/t-NaCl) under the following design basis. Quantity of waste brine 100,000(m2/D), production capacity 610,000(t-NaCl/Year), current density 7(A/dm*), electricity 5(YEN/KWH).Installation cost and Operating cost for recovery of salt have been substantially reduced, so electrodialytic concentration process appears more attractive than it has hither to been the case for the industrial use or manufacturing of table salt.
