ELECTROCOAGULATION SYSTEM FOR TREATING INDUSTRIAL WASTEWATER

The present invention refers to an electrocoagulation system for removing organic and inorganic matter and further particles suspended during the treatment of industrial wastewater by means of the coagulant generation in situ. The electrocoagulation system comprises an electrocoagulation cell, a current rectifier, a clarifier, a sludge tank, a supplying pump, a sludge pump, a pump for the clarified elements, a plate filter, a sand filter and a couple of activated carbons for purifying the treated water. The present invention provides an electrocoagulation cell integral with an electrode module, which reduces the number of elements, thus resulting in an easy construction and maintenance equipment. The operation of the cell uses a water flow that is parallel the electrodes, thereby reducing the incrustations therein and maintaining the cell efficiency. The clarifier contains a flocculation chamber, a chamber for removing foam, a sedimentation chamber and an other chamber for the clarifi ed elements, which use the characteristics of the cells for promoting the flocculation of the organic matter without using chemical reactants. The electrocoagulation system is useful for recirculating the sludges from the conditioning tank in order to reduce the consumption of coagulant generated in situ and using the coagulant present in the sludges, thus reducing the power demand of the cell, the system also treating the water for regenerating the filters so as to reduce the system purges that causes waste of water. La presente invención se refiere a un sistema de electrocoagulación para la remoción de la materia orgánica, inorgánica y otras partículas suspendidas en el tratamiento de aguas industriales, mediante la generación de coagulante "in situ".Es sistema de electrocoagulación comprende, una celda de electrocoagulación, un rectificador de corriente, un clarificador, un tanque de lodos, una bomba para la alimentación, una para lodos, una para clarificados, un filtro de platos, uno de arena y un par de carbón activado para pulir el agua tratada. Esta invención proporciona una celda de electrocoagulación que integra un módulo de electrodos, que reduce el número de elementos, resultando un equipo de fácil construcción y mantenimiento. En el funcionamiento de l celda se aprovecha un flujo del agua paralelo a los electrodos, reduciendo las incrustaciones en ellos y manteniendo la eficiencia de la celda. El clarificador contiene una cámara de floculación, una de desespumado,
