The system is a continuous and progressive process that takes place mainly on the liquid phase obtained from the mechanical separation, according to the following phases:
1.- Submersible agitator installed in the slurry pond in order to homogenise the slurry in the pond and facilitate the pumping system.
2.- Crushing and pumping of the homogenised slurry in the slurry receiving tank to the solid-liquid separator.
3.- Solid-liquid separation by means of a 0.45 mm. sieve. The resulting liquid effluent will continue with the next phase of treatment.
4.- Valorisation of the separated solid enriched in 90% of organic material and with a humidity between 30-40%.
5.- The Microfiltration stage is used for the refining of the liquid phase prior to the Water Electro Separation process. The filtering sieve of this phase is below 50 µm (0.0050 mm.) of passage light.
6.- Prior to the water electro-separation phase, if necessary, a chemical control and regulation system is implemented to control the pH and improve the coagulation and flotation of the solids that remain in the liquid.
In the final phase of the system, Electro Separation of Water with Advanced Oxidation (EWS:AOx) techniques are applied, integrating ORIGINCLEAR Technology.
7.- In the Electro-Flotation Phase, the product is dragged to the flotation area located under the metallic reactors, ensuring maximum contact between the water and the electrodes. Here the effluent is flocculated by micro bubbles of O2 generated by DC voltage induced hydrolysis on the electrode assemblies at the bottom of the tank. It is in this phase that the generation of Reactive Oxygen Species (ROS) such as Oxygen Peroxide (H2O2) and Hydroxyls (OH-) begins.
8.- The last phase of Advanced Oxidation (AOX) takes the water free of solids, from the Electro Flotation phase. In addition, disinfectants and decontaminants have begun to be generated by the reaction of the Reactive Oxygen Species.
By means of appropriate chemical dosing, the pH levels are kept under control.
The passage of the liquid effluent through the AOx reactor generates a large amount of ROS by direct contact with the anode surface, resulting in the reduction and removal of contaminants.
The residence time of the treatment will depend on the load of pollutants and the amount of energy required for their removal.
