Electrocoagulation

The fundamentals of this electrochemical process are the same as those of conventional coagulation. The main innovation is that the coagulant is generated on site by means of the electrolytic oxidation of the anode (iron or aluminium) which is consumed, hence removing the need to add other salts. Its main advantages are that it eliminates the majority of chemical reagents and generates much less sludge than conventional processes.

Electrooxidation

Its aim is to oxidise pollutant materials present in water. The anode is usually made of titanium with a sintered coating of noble metals with catalytic properties that allow the oxidation of pollutants either by direct contact with the anode or by oxidation in the medium. The design of the electrodes and their special sintering make them very long lasting with a higher oxidation capacity than other advanced oxidation technologies.

Electroperoxi-coagulation

This is based on electro-coagulation. The substantial difference is that while Fe²⁺ is generated on the sacrificial anode, the contaminants react with it and with hydrogen peroxide, which is added or generated cathodically. A Fenton reaction, which is characterised by the creation of highly oxidising environments, then takes place. The consumption of H₂O₂ is much lower than in other Fenton processes and its oxidation efficiency of the bio-refractory load is much higher.

Electrofenton

In this process, the catalyser is added in the form of metal salt and the hydrogen peroxide is generated cathodically. The process can be complemented with the supplementary addition of peroxide.

EQ TECH PILOT PLANT

Aqualogy has implemented two semi-industrial pilot plants (1 m³/h and 4 m³/h) to guarantee the correct operation of the previously designed process in laboratory tests and obtain its optimal design parameters, reducing the CAPEX and OPEX of the future industrial plant.
