Total dissolved solids removal by electrochemical ion exchange (EIX) process

摘要

In the present investigation, synthetic wastewater was prepared by the addition of required amount of salts into deionized water. Their performance, on removal of Cl{sup}-, (SO{sub}4){sup}(2-), (PO{sub}4){sup}(3-), Ca{sup}(2+), Fe{sup}(2+) and Mg{sup}(2+) in laboratory scale plate and frame type electrochemical ion exchange (EIX) cells, were evaluated under varying operating conditions. Ruthenium dioxide coated titanium plates (RuO{sub}2/Ti) were used as anode and stainless steel plates as cathode in all the four different EIX cells used in the present investigation. Ml the four EIX cells were run for a maximum of 7h. Almost complete removal of all the above ionic solids were observed within 4.5-7 h under one or more test conditions.
