Electrochemical advanced oxidation processes (EAOP) represent a very promising alternative for the treatment of drinking water, which consists in the electro-generation of oxidizing substances in a sustainable, green and chemical-free way. The aim of this Master Thesis is to study the feasibility of utilize an EAOP system, powered by renewable energy, for the disinfection of low conductive water. Therefore, a preliminary design of the reactor is proposed, estimating the sizing and the power required to power it and discussing possible solutions for system improvement. This work is part of the TrAcqua project, done in collaboration with ACDA, which provided the technical specifications that the reactor must meet.
