Waste-derived volatile fatty acids (VFAs) are emerging as a promising sustainable alternative to petroleum-derived VFAs. However, the post-treatment of waste-derived VFAs becomes imperative for the purpose of concentration, purification, and fractionation. This study delves into the application of the nanofiltration process for post-processing of solubilized VFAs, focusing on a comprehensive exploration of the influence of… Continue reading Evaluating the impact of membrane properties and feed pH on concentration and fractionation of volatile fatty acid using nanofiltration
This study was carried out with the scope of resource recovery platform from the food waste-based organic materials in the presence of in situ microfiltration immersed anaerobic membrane bioreactor. Afterwards, ultrafiltration technology was adopted. These microfiltration and ultrafiltration processes successfully removed larger particles, i.e., suspended solids from the anaerobically digested effluent. Moreover, ultrafiltration membranes (50 kDa)… Continue reading Microfiltration and Ultrafiltration as Efficient, Sustainable Pretreatment Technologies for Resource Recovery
Volatile fatty acids (VFAs) are building block chemicals that can be produced through bioconversion of organic waste streams via anaerobic digestion as intermediate products. Purified VFAs are applicable in a wide range of industrial applications such as food, textiles, cosmetics, pharmaceuticals etc. production. The present review focuses on VFAs recovery methods and technologies such as… Continue reading Factors influencing pressure-driven membrane-assisted volatile fatty acids recovery and purification-A review
Various methods exist for the recovery of volatile fatty acids from organic mixed waste effluents, and among them, the membrane filtration process holds a great promise over other recovery methods due to their simplicity, sustainability and high efficiency. Hence, in this study, nanofiltration experiments were carried out using two commercial nanofiltration membranes of 200–300 Da… Continue reading Feasibility of nanofiltration process for high efficient recovery and concentrations of food waste-derived volatile fatty acids
