Fig. 1From: Effect of voltage and electrode material on electroflocculation of Scenedesmus acuminatus Electroflocculation process. a Experimental setup: The flocculation experiments were carried out in 100-ml beakers filled with 90 ml of algae suspension. The electrodes were connected to a DC power supply (Hewlett Packard, Model 6205b, USA), b algae culture before flocculation, c during the flocculation process and d after the flocculation.Back to article page
