Experimental Study of Different Flocculants Used in High Turbidity Seawater Clarification

The experimental condition of three flocculants which were composite polymeric ferric,polymerized ferric chloride,ferrous sulfate used in high turbidity seawater was optimized through orthogonal experiment.Results showed that the turbidity removal efficiency of the flocculants in optimal condition reached 99.01%,96.80%,89.00% respectively.The composite polymeric ferric and polymerized ferric chloride had good flocculation to high turbidity seawater.Experiment results provided a reference for the choice of reagent in seawater desalination pretreatment,which had a certain significance.
