Abstract

Algae scum, which is inevitable in the algae water separation process, should be harvested and forbidden to discharge into the water. This paper studied the variation of algae scum in electro-coagulation-flotation (ECF) process. All experiments were conducted in the homemade electro-coagulation-flotation device, and the operating parameters included electric current density and operating time. The results showed that the variation of algae scum is affected by the operating parameters. With increasing of the electric current density and prolongation of the operating time, the moisture content of algae scum decreases gradually. On the contrary, with increasing of the electric current density and prolongation of the operating time, the slag water rate increases gradually. And the values of the moisture content and the slag water rate are relatively lower than other technologies. Overall, the results showed that the electro-coagulation-flotation (ECF) is a well suitable technology for algae water separation.
