“…Simultaneously, material properties like the charge density and hydrophilicity also influence the dewatering performance. These parameters control not only the dewatering performance but also the fouling tendency, swelling, chemical and cleaning stability, and lifetime of the membranes. − In the next sections, the contributions of the aforementioned parameters to the dewatering efficiency will be discussed in more detail.…”

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.

“…Recently, considerable research efforts have been focused on developing new membranes with high salt rejection efficiency for extended usage. Despite significant advancements in crafting superhydrophobic electrospun membranes for MD applications, challenges remain regarding their durability and robustness, mechanical strength, and ease of manufacturing [ 24 , 25 , 26 , 27 , 28 ]. Recent studies have highlighted that nanofiber membranes or composites incorporating nanoparticles, carbon materials, and bead-formation nanofibers can significantly enhance nanofiber membrane characteristics and performance [ 29 , 30 , 31 , 32 , 33 ].…”

This study introduces an innovative approach to enhancing membrane distillation (MD) performance by developing bead-containing superhydrophobic sulfonated polyethersulfone (SPES) nanofibers with S-MWCNTs. By leveraging SPES’s inherent hydrophobicity and thermal stability, combined with a nanostructured fibrous configuration, we engineered beads designed to optimize the MD process for water purification applications. Here, oxidized hydrophobic S-MWCNTs were dispersed in a SPES solution at concentrations of 0.5% and 1.0% by weight. These bead membranes are fabricated using a novel electrospinning technique, followed by a post-treatment with the hydrophobic polyfluorinated grafting agent to augment nanofiber membrane surface properties, thereby achieving superhydrophobicity with a water contact angle (WCA) of 145 ± 2° and a higher surface roughness of 512 nm. The enhanced membrane demonstrated a water flux of 87.3 Lm−2 h−1 and achieved nearly 99% salt rejection efficiency at room temperature, using a 3 wt% sodium chloride (NaCl) solution as the feed. The results highlight the potential of superhydrophobic SPES nanofiber beads in revolutionizing MD technology, offering a scalable, efficient, and robust membrane for salt rejection.
