ENVIRONMENTAL ENGINEERING AND ELECTROCHEMICAL TECHNOLOGY

Perhaps, you are thinking that I’m going to tell you that
electrochemical technology is the best set of
environmental remediation technologies…
… but be sure, this is not want I want to tell you. I just want to show
some cases in which electrochemical engineering could be of a
great help for the remediation of environmental problems and to
describe briefly the fundamentals of these technologies

Do not forget that electrochemical technology is…
…Not very appreciated in the conventional chemical industry:
 Low efficiency
 Too expensive
 Rarely tested at the full plant scale
 Not conventional
 …

And… why not? There is a very important question in the air: Could it be used
in Environmental Engineering?
