Algal biomass dehydration

Application of membrane dewatering for algal biofuel

“…In recent years, a number of review studies focusing solely or partly on algae dewatering have been published [9,10,22,25,[27][28][29][30][31][32][33]. Many of these studies outline potential algae dewatering technologies and investigate their efficiencies in terms of cost and energy consumption; however, limited discussion has been provided on the current research and issues related to using membrane filtration as a means of algae dewatering [9,10,22,31,33,34].…”

Integrated biorefineries: CO2 utilization for maximum biomass conversion

“…In parallel, intensive research is devoted to CO 2 utilization for producing fuel and products [54], and among them microalgae cultivation has gained significant research interest [55,56]. The diverse array of the algae research activities includes microalgae strain selection and lipid yield enhancement, [57][58] microalgae cultivation and dewatering [59], oil-extraction and different upgrading methods [60][61][62][63][64][65][66][67] With the aim of enhancing the overall biofuel yields and improving the environmental impacts, the present research proposes an integrated biorefinery comprising of biomass pyrolysis, in addition to solvent-based carbon capture and utilization through microalgae cultivation. The process integration is based on the synergies between the processing steps of these processes, as shown in Fig.…”

Sustainable Management of Algae in Eutrophic Ecosystems

“…There are many different methods for dewatering and concentrating algal biomass, and they vary greatly in both cost of implementation and energy consumption [44]. For the purposes of this initial design, preference was given to processes that would minimize the use of chemical coagulants and electricity (even if higher cost was incurred); as one of the primary goals of this project is sustainable water treatment for the lower Mississippi, it seemed counterintuitive to suggest processes that involve adding more chemicals to the water right before discharging it back into the river.…”

“…Dewatering and drying are typically the most costly aspects of any algae-to-energy process-drying alone usually accounts for 70% -75% of the entire production cost [44]. Dewatering is already built into the proposed design through the use of cross-flow filters; regardless, in keeping with the sustainability goals of this project, it would be prudent to consider only those processes which minimize energy input and cost.…”
