what countries have water shortagesIt has the benefits of little gadgets, small area covering, operation as well as monitoring quickly, greater COD removal price and great lightening impact, however the rainfall and also the usage of electrode product is fantastic, and the operating cost is high. The conventional electrochemical approaches can be separated into power flocculation, electric float, electro-oxidation, micro-electrolysis as well as the electrolysis approach. With the development of electrochemical modern technologies and also the showing up of a range of high efficiency reactor, the expense of treatment will certainly decrease largely. Electro-catalytic advanced oxidation process (AEOP) is a brand-new advanced oxidation technology developed lately. As a result of its high efficiency, simple procedure, as well as environmental kindness, it has drawn in the attention of researchers. Under regular temperature as well as pressure, it can produce hydroxyl radicals directly or indirectly through the reactions in the catalytic activity electrode, thus the degradation of the problem biodegradable contaminants works.
