A Spanish SME expert in a water debugging system focused on high organic matter and/or recalcitrant elements looks for distributors in Europe and South America.

A Spanish company dedicated to electrochemical treatments for the water purification has developed a brand new electrocoagulation based system to eliminate high organic loads and/or high level of suspended solids (slurry, oily waters, alcoholic waters ...) or with a high level of recalcitrant elements (nitrogen, phosphorus, metals heavy). Electrocoagulation can be defined as an electrochemical process during which the colloidal matter present in a quantity of wastewater is gathered together using compounds resulting from the dissolving of an anode in order to allow the colloids to be separated from the wastewater using conventional techniques. Because they dissolve, the anodes disappear during the course of the treatment, until the moment is reached when they need to be replaced. This means that they are ‘sacrificial anodes’. A series of processes then take place: ionization, destabilization, oxido-reduction, electrolysis, free radical formation, electromagnetic field formation, and emulsion breaking and separation. The head consists of the anode – which rests on the frame of the system - and the cathode, which is attached to a mobile structure with a pneumatic piston that allows the anode to be repositioned rapidly. The scraper is attached to the motor axle and it is for removing the sludge that adheres to the electrodes and ensuring uniform wear on the anode. The anode is toroidal in shape and has a cylindrical concentric cavity inside. The water being treated is driven by a pump towards the lower part of the anode. As a result of the action of the inlet pump, the internal cavity of the anode fills with water until the water overflows at the top. The water that overflows between the anode and cathode is collected in the lower part of the system using a conical funnel (depending on the model). It is at this point that –depending on the system model – the flocculant is added using a dosing system that consists of a storage tank and a peristaltic pump regulated by the programmable controller. Lastly, the treated water flows towards the sludge separation system where it is stored in the treated water tank and the floating sludge, precipitated sludge, and clarified water are separated. The floating sludge is sent to be decanted into a second tank to be extracted later on. The precipitated sludge is discharged via a manual valve installed on the treated water tank. The treated water is extracted using a simple separation system. The design of the electrocoagulation system can be adapted in line with the specific criteria of the project to produce one of the following system variants: - System with or without a sludge separation system. - System with or without a flocculant dosing system. - System with or without pH and conductivity control functions. - Depending on the volume of water to be treated, a fewer or greater number of reactors/heads can be installed without varying the rest of the system. The company is looking for distribution agreement in Europe and South America with a presence in the following markets. - Agri-food companies: pig farms, oil companies, alcoholic beverages manufacturers, cheese manufacturers - Companies with water polluting processes with nitrogen/phosphorus/heavy metals: mining, paper, fertilizers
