Abstract
Forward osmosis of microalgal suspensions was performed by using a dialysis membrane submerged in pure glycerol or a simulated crude glycerol of a biodiesel production process. Freshwater, marine and hypersaline microalgae were concentrated from around 1 to 2.5 g·Lâ 1 within an hour of treatment with crude glycerol. Cultures of marine microalgae could be osmotically dehydrated using crude glycerol as the draw solution at fluxes of around 2.75 L·mâ 2·hâ 1. This dewatering method was shown to be reliable and may be used in conjunction with other dewatering methods to improve the overall energy efficiency of a biomass recovery process.
