| Abstract: | This paper described a kind of natural material based organic flocculants with emphasis on the preparation and evaluation of flocculation properties. Two cationic flocculants (JK A and JK B) were made through quaterisation, and the products were tested by infrared spectrums to determine the completion of quaerisation. Evaluation was made on the basis of a series of jar tests of sewage flocculation for comparing the flocculants each other and with other flocculants such as aluminum sulfates, ferric chlorides and chitosan. |
