Flocculation of suspended particles by a thermosensitive polymer which shows a reversible hydrophilic/hydrophobic transition by heating or cooling its aqueous solution is examined. Poly (Nisopropylacrylamide) (poly NIPAM), whose transition temperature is about 32°C, is used as a thermosensitive polymer. Flocculation experiments were performed by a jar test with kaolin suspension. In the case of operating temperature lower than the transition temperature of poly NIPAM, there is an optimum polymer dosage, and by dosing excessively, kaolin particles are stabilized in the same manner as conventional polymeric flocculants. By heating the suspension above the transition temperature under the excess polymer dosage, however, the floc formation is observed. Furthermore, by cooling the suspension including flocs below the transition temperature again, the flocs were disorganized to the stabilized particles. From these phenomena, it can be concluded that the floc formation caused by heating above the transition temperature is due to the hydrophobic interaction of poly NIPAM molecules absorbed on the particles.
