Electrodeionization（EDI） as a combination of electrodialysis（ED） and ion exchange（IE）, has been gradually applied in pharmaceutical, electronic, electric power, biological technology, etc. In the paper, working principle was briefly illustrated. What＇s more, the specific applications of EDI in water for pharmaceuticals at home and abroad were emphatically analyzed. It was put forward that the integrated membrane process based on EDI and reverse osmosis（RO） would be one of the most promising technologies of pharmaceutical water production in the 21st century.
