- Abstract:
- It is an urgent problem to achieve timely, efficient, and cost-effective algae removal in the existing treatment processes of waterworks. In this study, a waterworks in Beijiang section of the Pearl River system was taken as an example to deal with algae pollution in the water source. The lab-scale test showed that when PAC containing 6% Al2O3 was used and the dosage was 20 mg/L, and the dosage of chlorine dioxide was 0.6 mg/L, most of the chlorophyll a in the water could be effectively removed, and the algae removal rate was as high as over 90%. In addition, the subsequent coagulation and precipitation effect could be strengthened.The above results were also verified in the full-scale test, and good results were obtained. The relevant results of this study will provide important data support for waterworks dealing with algae bloom outbreaks along the Pearl River system.
