“…27 ppm in C . calcitrans paste was a 97% reduction compared to electroflocculation using the 12‐volt car battery as a power source, as reported by de la Pena et al (2018). A further 77% reduction in Pb residue was obtained from Artemia fed C .…”

“…Despite the improvements on harvesting, feeding trials on a large scale and the issue on Pb contamination have not been thoroughly investigated despite metal contamination being found evident (Branyikova et al, 2018). High lead content was reported by de la Pena et al (2018) for C . calcitrans harvesting, with 1,318 ppm using a 3/6 units Al/Pb anode/cathode and 12 V nine plate battery as power source with.…”

An innovative microalgae harvesting technique was carried out under various anode/cathode (2/2, 4/4 and 6/6) configuration and at different voltage treatment (3, 6 and 10 V) to efficiently electroflocculate Chaetoceros calcitrans. This study was conducted to determine the optimal configuration of electrode units (Pb and Al) and voltage settings that could improve the quality of harvested paste in terms of nutritional value and metal contamination for its later use in aquaculture. The use of 6/6 electrodes achieved the shortest harvest time of 48 ± 1 min and the lowest Pb content (83.7 ± 0.3 ppm). In terms of voltage treatment, harvest time was inversely proportional to the voltage used. However, Pb content was significantly lowest in the paste produced using 3 V (41.78 ± 0.12 ppm), when compared to those harvested under 6 V (304.35 ± 0.79 ppm) and 10 V (343.90 ± 0.91 ppm) treatment. Likewise, Pb residues in the resulting effluent are also lowest (0.245 ± 0 ppm) with 3 V treatments. C. calcitrans paste can be resuspended ≤6 months but with a lag phase of 3–4 days for use as starter culture. A 97% reduction in Pb content of C. calcitrans paste and 77% reduction in Pb content were obtained in Artemia (7.8%) fed C. calcitrans paste.
