Abstract

The aim is to transform the electro-chemical oxidation process of organic pollutants in an industrial process which does not require the addition of any chemical reagent, does not generate sub-products that require new inertization treatments, have a faster kinesis than biological treatments and occupy a smaller physical space. It is intended to design, build and optimize electro-chemical reactors for the company’s use and to be commercialized. For this purpose, designs and tests will be undertaken aiming to anticipate the occurrence of problems arising from the transposition onto an industrial scale, with the proposal of possible solutions. The work also includes the design, detailed dimensioning and selection of materials for the reactor and its components, hydraulic installations, electrical installations and power supply and measuring and control instrumentation. A test module will be set up for experimental operation to support the project in terms of the optimization of the distribution of electrical current in the anode, the optimization of the distribution of fluid velocities, the choice of a suitable material for the turbulence promoter, and the processing of samples previously characterized for the evaluation of the reactor’s performance. The basic proposal of phase 2 of the project centers on the construction of a mobile effluent treatment station with a 60 m2 area of anodes for electrochemical treatment attached to ten photo-electrochemical reactors as complementary treatment. The mobile station will be placed into operation, for periods of two to three months in companies that have participated in the project up to the present time, which opened their effluent treatment stations so that the analytical monitoring of their waste could be carried out.
