Abstract

LA PRESENTE INVENCION PROPORCIONA UN METODO PARA ELIMINAR CONTAMINANTES DE FIBRA SECUNDARIOS, A PARTIR DE AGUAS DE PROCESAMIENTO DE PAPELERAS. DICHO METODO CONSISTE EN AÑADIR UN CLORURO DE POLIVINILO, UN COAGULANTE POLIMERICO CATIONICO Y UN FLOCULANTE POLIMERICO, A AGUAS DE PROCESAMIENTO DE PAPELERAS, QUE CONTIENEN CONTAMINANTES DE FIBRAS SECUNDARIOS, EN UNA CANTIDAD SUFICIENTE PARA AGLOMERAR DICHOS CONTAMINANTES EN FORMA DE TAMAÑOS DE PARTICULA MAYORES Y ELIMINAR DICHOS CONTAMINANTES SECUNDARIOS DEL AGUA DE PROCESAMIENTO, MEDIANTE UNA TECNICA DE CLARIFICACION POR FLOTACION DE AIRE DISUELTO. LA ADICION DE CLORURO DE POLIVINILO PARTICULADO EN COMBINACION CON UN COAGULANTE POLIMERICO Y UN FLOCULANTE, ANTES DEL PROCEDIMIENTO DE CLARIFICACION CITADO, HACE QUE LOS CONTAMINANTES RESULTEN PREFERENTEMENTE REVESTIDOS CON PARTICULAS DE CLORURO DE POLIVINILO. DICHO REVESTIMIENTO ES EL QUE HACE QUE LA POSTERIOR ELIMINACION DE LOS CONTAMINANTES DE FIBRAS SECUNDARIOS EN EL PROCEDIMIENTO DE CLARIFICACIONDESCRITO SEA MAS EFECTIVO.
