Colloidal silica is a kind of anionic colloidal silica with high specific surface area. It is one part of " compozil" retention system. " compozil" is a multifunctional retention and dewatering aid system which composed by one or more flocculants (such as cationic polypropylene acylamine and cationic starch) and colloidal silica.
