The paper deals with the possibility of using two-stage electrodialysis for recovery of lactic acid from model solutions and from fermentation broth. In the first step lactate was concentrated with desalting electrodialysis using ion exchange membranes Ralex (Mega,Czech Republic). The highest final concentration of 111 g/l was reached in the concentrate, it means an increase more than 2.5-times in comparison with the initial concentration. At the most 2 g of lactate per litre remained in the feed. The second step was the electroconversion of sodium lactate to lactic acid by water-splitting electrodialysis with the bipolar membranes Neosepta (Tokuyama Corp.,Japan). The final lactic acid concentration of 157 g/l was reached in the diluate. Total required energy in both electrodialysis processes consisting of the energy consumption for lactate transfer and for its electroconversion to lactic acid was 142 Wh/mol. The fermentation broth was decolourised before electrodialysis experiments. The best decolourisation capacity was shown by granulated active charcoal filled in the column operated by a slow flow of broth.

lactic acid, inclined tube sedimentation, ultrafiltration, flow velocity Abstract This study combined inclined tube sedimentation with ultrafiltration to remove the particles and protein in lactic acid fermentation broth. The influence of flow velocity on the extract property was investigated as well as the variations of flux, protein removal rate and lactic acid recovery in ultrafiltration. The result indicated that the inclined tube sedimentation was effective to remove the particles of fermentation broth. When the flow velocity was 0.031cm/s, the percentage of particles smaller than 10μm was 77%. The flow velocity 0.143cm/s in inclined tube sedimentation was more suitable in this study. SS removal rate can achieve 45.5% while protein removal rate and lactic acid recovery can be maintained above 90% in such situation

AbstractLactic acid has become one of the most important chemical substances used in various sectors. Its global market demand has significantly increased in recent years, with a CAGR of 18.7% from 2019 to 2025. Fermentation has been considered the preferred method for producing high-purity lactic acid in the industry over chemical synthesis. However, the recovery and separation of lactic acid from microbial fermentation media are relatively complicated and expensive, especially in the process relating to second-generation (2G) lactic acid recovery. This article reviews the development and progress related to lactic acid separation and recovery from fermentation broth. Various aspects are discussed thoroughly, such as the mechanism of lactic acid production through fermentation, the crucial factors that influence the fermentation process, and the separation and recovery process of conventional and advanced lactic acid separation methods. This review's highlight is the recovery of lactic acid by adsorption technique using ion-exchange resins with a brief focus on the potential of in-site separation strategies alongside the important factors that influenced the lactic acid recovery process by ion exchange. Apart from that, other lactic acid separation techniques, such as chemical neutralization, liquid–liquid extraction, membrane separation, and distillation, are also thoroughly reviewed.
