Flocculation and Removal of Algae in Urban Lake Water by Chitosan-modified Clays

Liu Lian(Guangdong Xindayu Environmental Engineering Co.,Ltd.,Guangzhou 510660 China)  
The flocculation and removal of algae in urban lake water by chitosan-modified clays was studied.The algal removal efficiency was greatly improved after the modification of the clays.Compare with chitosan alone,the chitosan-modified clays increased the density of flocs,reduced the flocs volume and improved the distribution of flocs.The optimized proportion between chitosan and clay was 1∶ 20,in which the best removal efficiencies of Chlorophyll-and turbidity were obtained.The different kinds of clays affected the algal removal efficiency.The algal removal capacity of high viscosity attapulgite was best.The optimum total loading was 28 mg·L-1 and the corresponding Chlorophyll-removal rate was 96.2%.The chitosan-modified clays with particle size ranging from 60μm to 300μm had almost the same algal removal efficiency,indicating that the particle size of clays did not have influence on the algal removal efficiency.The algal removal efficiency was higher in acidic conditions,and declined rapidly with the increase of pH in alkaline conditions.
