Abstract

UN METODO PARA LA FLOCULACION DE AGUAS RESIDUALES CONSTA DE UN COPOLIMERO BLOQUE QUE TIENE LA FORMULA: (FORMULA) EN DONDE E ES UN SEGMENTO POLIMERICO OBTENIDO DE LA POLIMERIZACION DE MONOMEROS HIDROFOBICOS, X CUANDO ESTA PRESENTE ES UN MONOMERO NO IONICO, Y ES UN MONOMERO CATIONICO, R1 Y R2 SON EL MISMO O DIFERENTES Y SON H O UN GRUPO ALQUILO INFERIOR DE C1 A C3 Y F ES UNA SAL DE UN CATION DE AMONIO. EL COPOLIMERO BLOQUE SE AÑADE AL AGUA RESIDUAL, PARTICULARMENTE AGUA RESIDUAL GRASA, PARA FLOCULAR LOS CONTAMINANTES.
