Abstract

PROCEDURE FOR THE TREATMENT OF RESIDUAL WATERS, BY FLOATING, by means of a gas evolution caused by the passage of an electric current between some electrodes immersed in said wastewater, characterized in that both electrodes are made of attachable metal and are fed by an invertible electric current, being carried out at a rate comprised between 10 and 3600 seconds the current reversal between the electrodes temporarily playing the anode trade and the electrodes temporarily playing the cathode trade.
