Removal of micropollutants and microorganisms from aqueous matrices

Electrochemical reactor for the removal of micropollutants and microorganisms from aqueous matrices applied in a time window of hours.

Technology overview

Electrochemical reactor for the removal of micropollutants and microorganisms from aqueous matrices applied in a time window of hours. Optimised for wastewater, this reactor provides an envelope for potential application in saline and brackish waters.

The electrochemical process is based on the application of a low intensity electric current between oppositely charged electrodes (anode and cathode). The induced electric potential promotes the electrolysis of water involving oxidation at the anode and reduction at the cathode.

A variant of this technology, based on the electrodialytic process, allows the simultaneous removal of organic contaminants and the recovery of phosphorus for subsequent reintroduction into the material flow.

This technology presents greater specifications in terms of design and implementation and the efficiency of its implementation depends on the matrix and contaminants under analysis.

Benefits

One of the advantages related to this technology is that there is no need to add reagents or chemicals. The electrons associated with the oxidation/reduction reactions are considered “green” agents.

The maximisation of uses and applications according to specific needs is one of the advantages of this technology. The technology can be individually designed or added to an existing technology (depending on its characteristics). The reactor can also be used stand alone or in a pipe designed for the removal of different contaminants.
