Summary: The search for new food products that promote consumers health is ongoing, with cheese whey (CW) and second cheese whey (SCW) proving to contain potential ingredients for the development of functional food products. While whey products have gained popularity for their nutritional quality, the by-products CW and SCW are often disregarded or used for animal feed, leading to environmental concerns. More research is needed on the nutritional and functional properties of SCW in order to find ways to reuse this by-product and reduce environmental impacts.

Summary: The increasing demand for phosphorus fertilisers for global food production and limited phosphate rock reserves have become emerging problems in the world. Cheese whey, with a high content of organic matter and phosphorus, is a promising option for phosphorus recovery. This study assessed the use of a membrane system coupled with freeze concentration to recover phosphorus from cheese whey. With optimal operating conditions and pre-treatment, 70% of phosphorus could be recovered, leading to a phosphorus-rich product with high agronomic value, contributing to a broader circular economy framework.

Summary: This study developed an integrated process for the recovery of sweet goat whey components through filtration, centrifugation, pasteurization, and sequential membrane processes. The application of this process led to the retention of proteins and lactose in whey, allowing for their total recovery in cheese dairy plants. This integrated process can contribute significantly to the sustainability of small- or medium-sized goat cheese dairies.

Summary: In this study, a transient back-pressure (water hammer) was applied to mitigate fouling in ultrafiltration of whey proteins. The water hammer effect was effective in reducing membrane fouling, with up to 84% flux enhancement achievable depending on operating conditions. However, the effectiveness of water hammer decreased at high transmembrane pressures and high feed concentrations where fouling was more severe.

Summary: A facile method was employed to fabricate tight ultrafiltration membrane for the removal of naturally existed hazard organic substances from surface water and wastewater. By using metal organic framework MOF of cerium (Ce), a new composite membrane was developed to enhance the performance of polyethersulfone (PES) membrane. The study showed that increasing the content of Ce-AnthMOF could significantly enhance the hydrophilicity and permeability performance of the membrane. Testing the membrane for the treatment of whey wastewater showed high removal rates of various pollutants, indicating a promising approach for efficient wastewater treatment.

Summary: Block freeze concentration (BFC) is an emerging technology that allows for the production of high-quality organoleptic products through low temperatures. This study investigated the effects of vacuum-assisted BFC on whey, specifically examining vacuum time, vacuum pressure, and initial solids concentration. The results showed significant impacts of these variables on solute yield and concentration index. By optimizing the conditions, it is possible to recover at least 70% of lactose in whey samples in a single step.

Summary: The antibacterial properties of cellulose acetate/silver nanoparticles (AgNP) ultrafiltration membranes were studied and the results showed that the distinct features of each side of the membranes, the active and porous layers surfaces, played a role in the antibacterial activity. The composition and structure of the membranes affected the accessibility of the silver to Escherichia coli (E. coli), leading to different levels of growth inhibition. The findings suggest that the membrane design and silver distribution can be optimized to enhance the antibacterial performance.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
