“…Cross-flow filtration is a conventional purification method in which a pressure gradient forces a fluid mixture flowing across a membrane to separate; it has been successfully utilized for separation of microalgae slurry [46], and an economic study of its utility in an industrialscale algal dewatering process estimated costs at around $0.75/kg dry biomass [47]. Cheaper options exist when chemical pretreatment of the algae slurry or dynamic filtration using a rotor are considered; however, those practices may not support the project's goal of minimal environmental impact.…”

The accelerated eutrophication of the world's freshwater and marine ecosystems is a complex problem that results in decreased productivity, loss of biodiversity, and various economic woes. Controlling algae populations in a eutrophic water body has values in mitigating some of these negative effects. This paper reviews a number of strategies for algae management, with a focus on sustainable practices that have minimal environmental impact. The information in the literature is then used to propose a design for an integrated algae-aquaculture system to be used for the dual purposes of nutrient assimilation and production of fish and algal biomass. Effectiveness of the proposed system and possible revenue streams to offset capital costs are examined; other solutions that utilize the techniques in the literature are also explored.

“…In addition to the membrane itself, the filterability of the feed can also be improved by adding a small amount of coagulant [19][20][21][22]. Coagulation/flocculation in itself is a renowned way to harvest microalgae [23].…”

“…Microalgae are kept in suspension, and shear stress is provided by cross-flow velocity, reducing cake formation and membrane fouling [19,20]. From an energetic point of view, requirements of cross-flow filtration are associated with the trans-membrane pressure required for permeate collection and the energy for pumping the suspensions through the membrane filtration system [21].…”
