Summary: The production of carboxylic acids and 1,3-propanediol from residual glycerol was studied, showing the highest yield at a substrate/microorganism ratio of 1.5. Acetic acid was the most concentrated bioproduct in all experiments, with propionic acid showing higher selectivity at a ratio of 1.5 and butyric acid and 1,3-propanediol at a ratio of 2.1. Exponential and sigmoidal models were used to describe process kinetics, correlating the substrate/microorganism ratio with velocity constant, maximum productivity rate, and lag phase time.

Summary: This study investigated the impact of ripening on the physical properties of mango purees through the study of their solid-like behavior, energy of cohesion, particle size, and sugar content changes. The results showed a sharp decrease in solid-like behavior and cohesion energy during the first 10 days of ripening, leading to a weakening of the gel-structure in mango purees. The size of suspended insoluble solids continued to decrease until 15 days of ripening.

Summary: Submerged forward osmosis (FO) is being widely used for treating and concentrating complex streams due to limitations of cross flow modules. This study designed submerged hollow fiber FO (Sub-HFFO) modules using commercial membranes, which showed similar performance to commercial cross flow modules. It was found that draw circulation in Sub-HFFO can be done in pulsing mode without mass-transfer limitation, thanks to homogeneous flow distribution and self-supporting membranes. Mixing near the membrane surface in the feed tank was identified as a key factor in mitigating fouling and external concentration polarization limitations.

Summary: The feasibility of predicting the fouling propensity of orange juice suspended particles based on their physical properties was investigated. Significant correlations were found between specific resistance to filtration (SRF) and hydration velocity (V-h), statistical diameter (D-90), and shear strain at flow point (gamma(f)). A simplified model based on 5 predictor variables allowed the discrimination of contrasted values of log(SRF) of suspended particles.

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.
