“…To achieve a satisfactory performance for biomaterial dewatering, researchers have been developing suitable membrane separations for various classes of biomaterials. Extensive literature can be found on the topic of microalgae harvesting, ,, protein concentration, − and polysaccharide removal . All of these dewatering applications require a high water/biomaterial selectivity and permeate flux, combined with minimal fouling (Figure ).…”

Biomaterials often contain large quantities of water (50−98%), and with the current transition to a more biobased economy, drying these materials will become increasingly important. Contrary to the standard, thermodynamically inefficient chemical and thermal drying methods, dewatering by membrane separation will provide a sustainable and efficient alternative. However, biomaterials can easily foul membrane surfaces, which is detrimental to the performance of current membrane separations. Improving the antifouling properties of such membranes is a key challenge. Other recent research has been dedicated to enhancing the permeate flux and selectivity. In this review, we present a comprehensive overview of the design requirements for and recent advances in dewatering of biomaterials using membranes. These recent developments offer a viable solution to the challenges of fouling and suboptimal performances. We focus on two emerging development strategies, which are the use of electric-field-assisted dewatering and surface functionalizations, in particular with hydrogels. Our overview concludes with a critical mention of the remaining challenges and possible research directions within these subfields.
