Microalgal bio-flocculation: present scenario and prospects for commercialization | Environmental Science and Pollution Research

17 Citations 1 Altmetric Explore all metrics Cite this article Abstract The need for sustainable production of renewable biofuel has been a global concern in the recent times. Overcoming the tailbacks of the first- and second-generation biofuels, third-generation biofuel using microalgae as feedstock has emerged as a plausible alternative.

Microalgae Chlorella vulgaris biomass harvesting by natural flocculant: effects on biomass sedimentation, spent medium recycling and lipid

Background Microalgal biomass harvesting using traditional chemicals is costly for the production of biofuels, hindering the scale-up process of the technology. Thus, the search for a cost-effective microalgal harvesting method is extremely important. Using chitosan as a natural flocculant to harvest microalgal biomass seems to be an efficient and convenient solution. Although microalgal

Transcript. Flocculation occurs both in natural systems, and it¡¯s also done intentionally in water treatment. Small particles of mud or sand that are present in water carry a charge, usually a negative charge. By adding a flocculant coagulant such as an aluminium salt ¨C and aluminium ions hold a positive charge ¨C those positive charges

There is a sigmoidal relationship between increase in cultural pH and flocculation efficiency for the freshwater alga Ettlia sp. YC001. The harvesting efficiency is very low at ~11% in the pH range of 6.5¨C8.5, while it dramatically increases to 83% and 94% with increase in pH to 10.5 and 12.5, respectively [ 37 ].
