    Harvesting of biomass from microalgal culture needs high energy inputs, as small algal cells need to be separated from a large volume of surrounding media. The biomass harvest of Nannochloropsis oculata was evaluated using electroflocculation. Different electrodes like Aluminum, Zinc, Copper, Brass and Iron were used as both anode and cathode. The electrodes were connected to DC supply and the flocculation was performed at different voltages viz; 20,40,60,80 and 100 V at constant power (90mA) and time (30 minutes). From the above study, it was concluded that Zinc electrodes performed better with 80% harvesting efficiency at 40V. The flocculated cells by Zinc electrode were 80% viable which was confirmed by inoculating the flocculated cells
