Flocculation behavior of colloidal suspension by use of inorganic and polymer ﬂocculants in powder form

The clariﬁcation method by using composite dry powdered ﬂocculants consisting of inorganic ﬂocculant, polymer ﬂocculant and ﬂocculation aid has been proposed in the literature. Such composite ﬂocculants are conveniently used in the ﬂocculation process of small volume suspensions; i.e. the composite...
