Basic information on electrochemical electrocoagulation technology
The electrocoagulation process is similar to the typical physical-chemical treatment, but using electrical energy.
Electrocoagulation can be defined as an electrochemical process in which, from compounds resulting from the dissolution of an anode (sacrificial anode), the colloidal matter in wastewater is gathered together, thus enabling its separation through conventional techniques.
Electrocoagulation is an electrochemical process with the same basis as conventional coagulation. The main innovation is that the coagulant is generated in situ by the anode electrolytic oxidation (iron or aluminum) which is sacrificed, so it is not necessary to add other salts.
The electrocoagulation process is very similar to normal chemical-physical coagulation – the difference is that it uses electrical energy. Both processes aim to destabilize the colloids contained in a quantity of water, but they differ in the method used to add the reagent: in conventional coagulation, the reagent is added as a salt, whereas in electrocoagulation, it is generated from a metal. Electrocoagulation can be defined as an electrochemical process during which the colloidal matter present in a quantity of wastewater is gathered together using compounds resulting from the dissolving of an anode in order to allow the colloids to be separated from the wastewater using conventional techniques. Because they dissolve, the anodes disappear during the course of the treatment, until the moment is reached when they need to be replaced. This means that they are ‘sacrificial anodes’.

Basic Information: PROELEC
PROELEC executes a controlled electrochemical process that destroys toxic compounds. In almost all cases, PROELEC improves the chemical-physical traditional treatment, so that in addition to flocculate and coagulate, PROELEC is also executing a partial oxidation of the biodegradable contamination and a partial oxidation of the non-biodegradable contamination. In fact, depending on how we proceed and depending on the quality of the water to treat, we can oxidize soluble COD in yields of up to 95% or even more.
