Electrochemical harvesting of Chlorella sp.: Electrolyte concentration and interelectrode distance

Two modes of electrochemical harvesting for microalgae were investigated in the current work. A sacrificial anode (aluminum) was used to study electrocoagulation-flotation process, and a nonsacrificial (graphite) investigate electroflotation process. The inspected effect chloride ions concentration interelectrode distance on performance processes. results demonstrated that both electrodes achieved maximum efficiency with 2 g/L NaCl concentration. Interestingly, by increasing 5 g/L, reduced dramatically its lowest value. Generally, energy consumption decreased Moreover, aluminum anodes is lower than graphite. However, gap between from 15 mm 30 mm, time required achieve doubled, increased consequently.
