Abstract—Existing process for a detergent factory of de-mineralized water system was as the main research object. According to its water quality characteristics and the investigation for original desalting process, desalting process design was made. Then test experiment was proceeded at 1.2m3/h scale, and the system was divided into three subsystems: Pretreatment, Reverse osmosis desalting system and Electrodeionization treatment system. And stability of new craft was investigated at pilot scale, Results showed that in this craft, SID of ultra filtration effluent was less than 2, desalting ground water completely served as boiler water, and Electrodeionization meet the requirement for processes pure water after secondary treatment. But Electrodeionization effluent quality deteriorated occasionally, so Sodium hydroxide was added by metering

Index Terms—Desalting process, test experiment, pilot scale, electrodeionization.
