Beschreibung
Zusammenfassung:	A retention and drainage aid comprising a microparticle system for use in the production of an alkaline and an acid paper product comprises a flocculant polymer and an inorganic particulate material comprising an aluminum substituted trioctahedral mineral, and optionally a cationic coagulant. The polymer flocculant is added to the furnish after the fan pump and prior to the pressure screen; the inorganic particulate material is added to the furnish after the pressure screen, and optionally, the coagulant is added prior to the fan pump.
