| Research Abstract |
A new waste water treatment process with a pressure-responsive polymer was developed. In waste water treatment process, it is ideal process controllable initiation of flocculation of particles in a slurry. There are techniques to control initiation of flocculation using temperature-responsive polymer such as PNIPAm. However, its technique is not so easy to handle because it is very expensive and requires high-accuracy temperature control. In this research, it is discovered that this may also be accomplished by using inexpensive Pressure-Responsive Polymer such as ammonium polycarboxylate. The results of the investigation showed that the conformation of adsorbed polymers changed with pressure from fibril-like to random coil and the dispersion state of the slurry changed with the contracting of the conformation of adsorbed polymers. Furthermore, this technique is so easy to control because the propagation time of a pressure is very short.
