In our work, we focused on deep examination of various parameters influencing the separation efficiency of the electrocoagulation and iron content in the separated biomass of Chlorella vulgaris. Influence of current/voltage, electrodes distance, agitation, culture media components, pH, temperature, initial microalgae suspension density, agitation etc. was tested in a laboratory apparatus operated in a batch mode. The obtained knowledge was applied in construction and operating settings of a pilot scale continuous device (volume of 50 L). We were able to separate Chorella vulgaris from suspension with 98% efficiency and decrease the biomass separation costs to 0.15 kWh/kg, which was 7.5 % of the energy consumed by centrifugation.
