Using electricity to treat water was first proposed in
United Kingdom in 1889 [10], [12]. The
electrocoagulation of drinking water was first applied on a
large scale in the United states in 1946 [2], [13]. Because
of the relatively large capital investment and the
expensive electricity supply, electrochemical treatment of
water or wastewater technologies did not find application
worldwide [11], [14]. However, due to extensive research
in United States and USS Russia during the following half
century, the process has gained large amount of
knowledge. With the ever-increasing stringent
environmental regulations regarding the wastewater
discharge, electrochemical technologies have regained
their importance worldwide during the past two decades
[4], [7]. Now a days, electrochemical technologies have
reached a state that they are not only comparable with
other technologies in terms of cost but also potentially
more efficient and for some situations electrochemical
technologies may be the indispensable step in treating
wastewaters containing refractory pollutants [3], [9].
