A Simple, Cost-Efficient Method to Separate Microalgal Lipids from Wet Biomass Using Surface Energy-Modified Membranes
For
the efficient separation of lipid extracted from microalgae cells,
a novel membrane was devised by introducing a functional polymer coating
onto a membrane surface by means of an initiated chemical vapor deposition
(iCVD) process. To this end, a steel-use-stainless (SUS) membrane
was modified in a way that its surface energy was systemically modified.
The surface modification by conformal coating of functional polymer
film allowed for selective separation of oil鈥搘ater mixture,
by harnessing the tuned interfacial energy between each liquid phase
and the membrane surface. The surface-modified membrane, when used
with chloroform-based solvent, exhibited superb permeate flux, breakthrough
pressure, and also separation yield: it allowed separation of 95.5 卤
1.2% of converted lipid (FAME) in the chloroform phase from the water/MeOH
phase with microalgal debris. This result clearly supported that the
membrane-based lipid separation is indeed facilitated by way of membrane
being functionalized, enabling us to simplify the whole downstream
process of microalgae-derived biodiesel production
