The use of chitosan to improve membrane filter performance. |
| 摘要 |
<p>Improvement in cross-flow membrane filtration. Chitosan is admixed with an aqueous dispersion of colloids or finely divided solids to flocculate the solids. The chitosan-flocculated liquid is then filtered on a membrane by cross-flow under pressure. A layer of chitosan-containing flocculant material deposits on the membrane and provides superior flux performance as compared to certain commercial flocculants.</p> |
