| Outline of Final Research Achievements |
It was found that the osmotic pressure of the concentrated layer formed by particle settling and thickening increased with an increase in particle concentration, however, the osmotic pressure was quite small as a draw solution of FO process. It was suggested that the combination of a polymer solution or inorganic salt solution which can produce a relatively large osmotic pressure due to its large number concentration of molecules should be necessary. Therefore, the alumina slurries containing a temperature responsive polymer, PNIPAM were prepared and investigated its potential as a novel draw solution. It was demonstrated that suction and separation of water could be easily and repeatedly done by changing the temperature of the stimulus responsive slurry.
