“…41 Considering the LPP10 membrane as an example, the molecular weight was 705 Da, which was much larger than the molecular weight of SDZ (250 Da), suggesting that the size exclusion of SDZ by LPP10 was unrealizable. 42 This also corresponds to other PBA−LDH@PDA membranes. Second, the SDZ rejection ratio of LPP10 remained basically constant from the beginning to the final filtration period, which suggests that the SDZ degradation was the dominant SDZ rejection mechanism as the adsorption usually occurred during the initial filtration period.…”

In this study, a Prussian blue analogue (PBA)-intercalated magnesium aluminum hydrotalcite (PBA–LDH) material was used to successfully modify the membrane surface by layer-by-layer synthesis with an intermediate layer inspired by dopamine polymerization (polydopamine (PDA)). The PBA–LDH@PDA membrane was endowed with highly efficient peroxymonosulfate (PMS) activation and superb antifouling properties. Quenching experiments implied that SO4 •– mainly contributed to the sulfadiazine (SDZ) degradation in the PBA–LDH@PDA membrane-activated PMS system and performed well under various conditions. On the other hand, the PBA–LDH@PDA membrane was confirmed to exhibit separation by loose nanofiltration. The fouling performance of the membrane identified an extremely low flux attenuation even when 60 mg/L bovine serum albumin (BSA) was filtered. Multicycle filtration experiments demonstrated extremely low fouling accumulation of the membrane. The loose nanofiltration membrane with PMS activation properties possesses multiple advantages: activation of PMS by the filtration process provides a space in which the catalyst, oxidant, and foulant can completely react; the two goals of fouling mitigation and target foulant removal can be mutually realized by controlling the operating parameters (e.g., PMS dosage and filtration pressure). Overall, this study provides a beneficial strategy for improving the efficiency of membrane filtration and foulant removal.

“…The concentrated flow contains high-concentration wastewater, while the permeated flow contains purified water. The osmosis process occurs through a pressure gradient that causes water molecules to move from the high-concentration flow to the low-concentration flow [ 4 ]. In the bioreactor flow, microorganisms are used to break down organic matter and remove pollutants from the wastewater.…”

This study explored the use of a combination of hydrothermal and sol–gel methods to produce porous titanium dioxide (PTi) powder with a high specific surface area of 112.84 m2/g. The PTi powder was utilized as a filler in the fabrication of ultrafiltration nanocomposite membranes using polysulfone (PSf) as the polymer. The synthesized nanoparticles and membranes were analyzed using various techniques, including BET, TEM, XRD, AFM, FESEM, FTIR, and contact angle measurements. The membrane’s performance and antifouling properties were also assessed using bovine serum albumin (BSA) as a simulated wastewater feed solution. Furthermore, the ultrafiltration membranes were tested in the forward osmosis (FO) system using a 0.6-weight-percent solution of poly (sodium 4-styrene sulfonate) as the osmosis solution to evaluate the osmosis membrane bioreactor (OsMBR) process. The results revealed that the incorporation of PTi nanoparticles into the polymer matrix enhanced the hydrophilicity and surface energy of the membrane, resulting in better performance. The optimized membrane containing 1% PTi displayed a water flux of 31.5 L/m2h, compared to the neat membrane water value of 13.7 L/m2h. The membrane also demonstrated excellent antifouling properties, with a flux recovery of 96%. These results highlight the potential of the PTi-infused membrane as a simulated osmosis membrane bioreactor (OsMBR) for wastewater treatment applications.

“…The submerged membrane bioreactor (MBR) is a cutting-edge membranebased treatment method for enhanced wastewater treatment. 4,5 It integrates biological treatment processes with semipermeable membranes. For the removal of antibiotics from wastewater, functionalized mixed matrix membranes in the MBR offer remarkable advantages, including more excellent antibiotic removal, decreased fouling propensity, lower energy consumption, and lower operating costs.…”

“…Literature studies show that from the wastewater stream, the antibiotic removal is carried out using the MBR system. 5,11,12 PAMAM-coated membranes are used to investigate the antibiotics lasalocid A, salinomycin, and semduramicin as ionophore antibiotics in pharmaceutical wastewater. For lasalocid A, salinomycin, and semduramicin, they reported 82.5, 87.3, and 91.3% removal, respectively.…”
