Summary: Cellulose extracted from rice straw waste was transformed into nanocellulose acetate (NCA) to prepare cellulose acetate reverse osmosis (RO) membranes. The nanocellulose had a small particle size and spherical shape, while the developed membranes had a lower contact angle and enhanced hydrophobicity. The NCA: CA ratio of 40:60% in the membranes resulted in high salt rejection and water flux, as well as resistance to protein adsorption and microbial growth.

Summary: An optimization of formulation-induced structure strategy was developed to enhance the performance of cellulose acetate butyrate (CAB)-based reverse osmosis (RO) membrane. The addition of acetone, triethyl phosphate, glycerin and n-propanol resulted in a state-of-the-art salt rejection rate and permeate flux, surpassing previous CAB-based RO membranes. The optimized micro-structure of the membrane provided good separation performance for various concentrations of ions and dyes, as well as resistance to changes in feed pressure.

Summary: The study investigated the optimal polymeric blending ratio between cellulose acetate (CA) and polyvinylidene fluoride (PVDF) to create a blended polymeric membrane with enhanced properties. The inclusion of nano-sized metal organic framework (UiO-66 MOF) further improved the membrane performance. The resulting hybrid membrane showed promising salt rejection and permeate water flux for water desalination applications.

Summary: In this study, cellulose acetate (CA) silica-based nanocomposite membranes were fabricated using the dry-wet phase inversion procedure for water desalination. The effects of SNPs and MSNPs on the properties and performance of the CA membrane were investigated. The fabricated nanocomposite membranes exhibited hydrophilic surface properties and showed enhanced water flux by adding SNPs and MSNPs.

Summary: This study developed hollow fiber membranes for OARO operation and investigated the relationship between membrane structure and resistance to compaction during long-term operation. The results showed that the mechanical properties and performance of the membranes under reverse osmosis conditions were highly correlated with their long-term performances and dimensional stabilities under OARO conditions.

Summary: In this study, a solvent exchange method was used to treat cellulose acetate/cellulose triacetate forward osmosis (CA/CTA FO) membrane, resulting in increased micropores and mesopores, and improved reverse salt flux and pure water flux by 65% and 20% respectively. The treatment also led to a 55% increase in selectivity and a 40% reduction in structural parameter, contributing to enhanced membrane performance.

Summary: By incorporating sulfonated COFs into CTA/CA membranes, the FO performance was enhanced through increased membrane porosity, reduced structural parameter, and improved hydrophilicity. The synthesized TATP-SO3H COF with an ideal pore size showed high rejection to salt and easy water passage. XPS results confirmed the presence of H-bonding between TATP-SO3H and CTA/CA, leading to improved flux and selectivity in FO mode.

Summary: This study compares several technologies for reducing the volume of reverse osmosis concentrate in order to achieve zero liquid discharge in the coal chemical industry. The results show that the forward osmosis-reverse osmosis scenario performs the best in terms of water recovery, while disc tube reverse osmosis and vibratory shear enhanced process are more effective in reducing the concentrate volume. For a full-scale plant, disc tube reverse osmosis offers the lowest cost.

Summary: The hollow fiber composite reverse osmosis membrane with a special self-supporting structure has gained significant attention. However, its low permeability is a major obstacle to its wide application. In this study, a porous polysulfone hollow fiber support membrane was fabricated by incorporating hydrophilic alpha-cellulose powder to improve the membrane's water permeability. The effects of alpha-cellulose incorporation on the separation performance of the membranes were investigated.
