BackgroundMicroalgae are a promising new source for biomass production. One of the major challenges in regards to cost effectiveness is the biomass harvest. High energy input is required for the separation of the small algal cells from a large volume of surrounding media. Electroflocculation is reported as a promising harvesting technique to improve cost effectiveness within the downstream process. In the present study, six electrode materials were tested for electroflocculation of Scenedesmus… 

Investigation of electrolytic flocculation for microalga Scenedesmus sp. using aluminum and graphite electrodes

Electrolytic flocculation using non-sacrificial electrodes with flocculants added was studied on harvesting Scenedesmus sp. In order to optimize the operating conditions of the electrolytic

Harvesting of freshwater microalgae Scenedesmus sp. by electro–coagulation–flocculation for biofuel production: effects on spent medium recycling and lipid extraction

ECF-based microalgae harvesting was found as a low-cost technique and neutralizing pH and supplementing macro- and micronutrients enabled the flocculated medium to maintain an approximate growth yield in algal cultivation to that of the fresh BG11 medium.

This study aimed to search for a proper system for electro-flotation harvesting of microalgae Dunaliella salina with a minimization of metal contamination. An applied electrical current caused cell

Treatment of paper-recycling wastewater by electrocoagulation using aluminum and iron electrodes

It can be concluded that EC could be considered as an effective alternative for treatment of paper-recycling Wastewater using aluminum and iron plate electrodes.

Comparison of Different Anode Materials to Remove Microcystis aeruginosa Cells Using Electro-Coagulation–Flotation Process at Low Current Inputs

Cyanobacterial blooms are a threat to the drinking water supply owing to their potential toxicity. Microcystins which are the most widespread cyanotoxins, are mainly produced by Microcystis spp. In



Factors affecting microalgae harvesting efficiencies using electrocoagulation-flotation for lipid extraction

Microalgae harvesting is a relatively costly process in microalgae biodiesel production. In this study, electrocoagulation-flotation (ECF) was employed to harvest microalgae (Chlorella vulgaris).

Harvesting Chlorella minutissima using cell coagulants

Twelve salts were tested for their ability to coagulate microalgae cells in cultures of Chlorella minutissima. The final aim was to develop an easy and efficient approach for harvesting microalgae

Algal flocculation with synthetic organic polyelectrolytes.

The mechanism of chemically induced algal flocculation is interpreted in terms of bridging phenomena between the discrete algal cells and the linearly extended polymer chains, forming a three-dimensional matrix that is capable of subsiding under quiescent conditions.

Microalga Scenedesmus obliquus as a potential source for biodiesel production

The presence of palmitate and oleate as the major constituents makes S. obliquus biomass a suitable feedstock for biodiesel production, and the lipid content increased under N-deficiency and thiosulphate supplementation.
