One of the main current worldwide concerns is the growth of water pollution by organic compounds arising from many industrial, agricultural and urban human activities. The vast majority of these compounds are persistent organic pollutants, owing to their resistance to conventional treatments such as coagulation, biological oxidation, adsorption, ion exchange and chemical oxidation. As a result, they have been detected in rivers, lakes, oceans and even drinking waters all over the world. This constitutes a serious environmental health problem mainly due to their toxicity and potential hazardous health effects (carcinogenicity, mutagenicity and bactericidality) on living organisms, including human beings.

Over around the past three decades, research efforts have been made at developing more effective technologies to totally remove persistent organic pollutants from wastewaters. In this context, electrochemical advanced oxidation processes (EAOPs) acquired high relevance. EAOPs are based on the in situ production of highly reactive hydroxyl radicals that non-selectively react with most organics, being able to degrade even highly recalcitrant compounds. The EAOP method is a electrochemical purification method that is used to eliminate problematic organic matter and to degrade and decompose materials that are not readily and completely decomposed by oxidation and conventional biological methods. The main advantage of the AOP method is its ability to produce high concentrations of radical hydroxyl. As a strong oxidizer, this radical is capable of oxidizing most organic compounds to carbon dioxide, water, and mineral acids.

The electrochemical methods have been recognized as simple, smart, portable, and environmentally friendly, since electrode itself acts as a reactant in the redox reaction. O₂ dissolved in solution is known to be electroactive and can be reduced electrochemically.

The company’s scientific team has created a technology-MPECT (MultiPhase ElectroChemical Treatment) for electrochemical treatment of effluent toxic wastewaters. The technology is a set of reagent free water purification methods based on the principles of electrochemical action and innovative filtration methods.

MPECT- electrochemical advanced oxidation processes (EAOPs) have gained increasing attention as a promising class of AOPs .The former, simplest and most popular EAOP is anodic oxidation (AO), where organics can be directly oxidized at the anode surface by electron transfer and/or indirectly oxidized by radical OH weakly physisorbed at the anode surface and/or agents at the bulk solution such as active chlorine species, O₃, persulfates and H₂O₂.
