电渗析饮用水的稳定指数＞９．０，其侵蚀度高达０．５９ｍｍ／ａ具有极严重的腐蚀性，是某油田生活供水管网产生“红水”和严重锈蚀的根本原因；水中铁细菌和硫细菌的大量存在则是管道结瘤、堵塞的生物学原因。电渗析淡水经再矿化后，侵蚀度＜０．０５ｍｍ／ａ，不仅可以保护管道，还改变了水型，改善了饮水质量 Electrodialysis drinking water stability index> 9.0, the erosion of up to 0.59mm / a has a very serious corrosive, is the root cause of a field of domestic water supply pipe “red water” and serious corrosion; iron bacteria in water And sulfur bacteria is the existence of a large number of pipe nodules, clogging of the biological reasons. Electrodialysis freshwater after remineralization, the degree of erosion <0.05mm / a, not only can protect the pipeline, but also changed the water type, improved drinking water quality
