B. Equipment and Electrolysis
The experimental facility for algae removal by ECEF
process is schematically shown in Fig. 1. The electrolytic
cell with a width of 25 cm, a length and a depth of 30 cm
was a glass reactor equipped with a magnetic stirrer.
Electrodes plates (20 cm x 10 cm x 0.1 cm) made from
aluminum or copper were selected for the anode and graphite
was used for the cathode. The electrode assembly consisted
of three anodes and three cathodes according to the electrode
arrangement connected in monopolar mode, with an effective
area of 1000 cm2
and the interelectrode distance of 1.5 cm.
This was submerged into the algal solution at a height of 2
cm from the bottom and was connected to a direct current
power supply source (GW GPR-6060D) which meant the
ECEF cell could be operated in a galvanostatic mode with a
constant current. The algal solution was characterized by a
pH meter (SevenEasy Mettler Toledo) and a conductivity
measurement (Orion 4 stars Thermo Scientific).
