In this work, the non-ionic polyethylene oxide(PEO)/phenolic formaldehyde resin(PFR) retention system, which was less affected by furnish charge, was analyzed for possibility and effectiveness when using recycled stock. When the micropolymer was added at the PEO/PFR retention system and the PAM/bentonite retention system, performance of retention and drainage was improved. When the cationic micropolymer was added on the PEO/PFR retention system, the highest retention was achieved. The Polyacrylamide(PAM)/bentonite system induced flocculation of white pitch by electrostatic flocculation. On the other hand, the non-ionic PEO/PFR retention system induced less flocculation of white pitch than the PAM/bentonite retention system.
