Annotation	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.
