Algae Harvesting

Microalgae are of interest to the aquaculture, animal feed, pharmaceutical, cosmetic and biofuel industries due to their ability to synthesise a wide range of valuable compounds, such as omega 3 fatty acids, carotenoid pigments including astaxanthin and biodiesel precursors. Harvesting algae after cultivating to high concentrations is a key stage in the process used to turn raw algae into a valuable product. Currently, commercial microalgal production is limited to high-value nutraceuticals and personal care products, in part due to the expense of harvesting technology, which tends to be undertaken via centrifugation in commercial operation. Cost-effective, efficient separation processes are needed to extend the range of economical microalgal products. The focus of the AOM Lab's research in this area is to develop processes that have advantages over other conventional harvesting processes including high solid output, minimal chemical dosing, ease of scale-up and energy efficiency.
