Abstract

Las mezclas de polímeros de acrilamida de Mannich y de poliamidas cuaternarias han demostrado ser floculantes superiores para las corrientes de caldos enzimáticos proporcionando mayor compactación de los sólidos y superior claridad de sobrenadante que mediante el uso de cualquiera de los polímeros solos.
