Flux decline in crossflow ultrafiltration-based diafiltration process for lignin recovery from a deep eutectic solvent comprised of lactic acid and choline chloride

Pressure-driven membrane processes for the recovery and recycling of deep eutectic solvents: A seaweed biorefinery case study.

“…These results can also point towards fouling not being present. In the their most recent study, Gholami et al [55] showed not only that the growth of the fouling layer reduces the recovery ratio for the second and third diafiltration steps, but also that higher solute and DES concentrations increase filtration resistance [ 55 ]. However, by the end of the diafiltration steps in this present study, the recovery of the DES was not hindered.…”
