Abstract

EL AGUA DE LAVADO PROCEDENTE DE INSTALACIONES DE LAVADO DEL SUELO, QUE DISPONE DE EMULSIONES ACEITE/AGUA Y SUSTANCIAS SOLIDAS EN FORMA DE SEDIMENTO DE SILICATO (TAMAÑO DE PARTICULA MENOR DE 60 MICRAS), SE DESDOBLA BAJO UTILIZACION DE AGENTES DE DESDOBLAMIENTO DE EMULSION/FLOCULACION ORGANICOS CATIONICOS Y CONTROL DE DOSIFICACION CON LA AYUDA DE POTENCIAL DE CORRIENTE ELECTROCINETICO EN TRES COMPONENTES. EL MEDIO DE DESDOBLAMIENTO SE DOSIFICA HASTA UN PRIMER AUMENTO DEL POTENCIAL DE CORRIENTE A TRAVES DEL VALOR MINIMO, QUE SEPARA EL SEDIMENTO LIBRE DE ACEITE FLOCULADO, SE RENUEVA EL MEDIO DE DESDOBLAMIENTO HASTA UN AUMENTO DEL POTENCIAL DE CORRIENTE MEDIANTE DOSIFICACION PARA LA OBTENCION DE UN SEGUNDO VALOR MINIMO Y SE SEPARA LA FASE DE ACEITE QUE FLOTA.
