| Abstract: | A cationic starch with high degree of substitution developed in laboratory was used as the flocculant to treat the white water from paper mill. The effects of the dosage of the said cationic starch, the pH value of the waste water and the time of flocculation on the result of the flocculation were approached through experiments, with the optimum conditions for the treatment of the white water from paper mill using the said cationic starch so determined that the dosage of the said cationic starch should be 200 mg/L without adjusting the pH value, which will give a flocculating time of 24 hours. |
