Abstract

LA INVENCION TRATA DE UN PROCEDIMIENTO PARA TRATAR EL AGUA DE ACLARADO PROCEDENTE DE MAQUINAS LAVADORAS O DE LIMPIEZA, QUE ESTA CARACTERIZADO PORQUE: A) EL VALOR DE PH DEL AGUA DE ACLARADO ALCALINA SE REDUCE EN CONTACTO CON DIOXIDO DE CARBONO HASTA QUE LA MEMBRANA DE LA OSMOSIS INVERSA YA NO ES ATACADA POR LA SOLUCION, EMPLEANDOSE COMO FUENTE PARA EL DIOXIDO DE CARBONO, AL MENOS PROPORCIONALMENTE, LA MEZCLA DE GAS OBTENIDA POR EL TRATAMIENTO TERMICO DEL GAS DE FERMENTACION QUE SE FORMA POR LA DEGRADACION ANAEROBIA DE SUSTANCIAS ORGANICAS Y/O LA MEZCLA DE GAS QUE SE PRODUCE POR LA DEGRADACION AEROBIA DE SUSTANCIAS ORGANICAS; B) LA SOLUCION ASI OBTENIDA SE SOMETE A UNA OSMOSIS INVERSA Y C) LA PENETRACION OBTENIDA SE EMPLEA PARA FINES DE ACLARADO Y ELIMINA EL CONCENTRADO.
