“…This observation can be explained by the fact that glycerol was retained by the membrane and due to the In the literature, there is general agreement that the observed phenomenon is typical for membrane processes. Furthermore, flux decline during the separation of fermentation broths with the use of various NF membranes has been widely reported in previous studies [7,50,57,62,63,65,66]. For instance, Thuy et al [65] noted that in the first few minutes of separation of clarified succinic fermentation broth with the use of a spiral-wound NF membrane, the permeate flux decreased from 1.22 L/m 2 h to 0.2 L/m 2 h. The above-mentioned authors have shown that after 21 h of the NF run, the flux was equal to 0.09 L/m 2 h which corresponded to a 92.6% reduction in comparison to the initial flux.…”

“…Furthermore, it has been noted that the separation performance was strongly affected by the pH, transmembrane pressure (TMP), and broth concentration. In turn, in a recently published research paper [62] it has been clearly demonstrated that NF is an effective strategy to purify xylitol obtained by fermentation of sugarcane bagasse hemicellulose hydrolysate.…”

“…Briefly, the literature findings reveal that NF has been successfully used for the treatment of drinking water [41][42][43], wastewater reuse [44][45][46], and food processing [47][48][49]. In addition, recent years have witnessed a growing interest in applying the NF to separate various components from actual and synthetic fermentation broths [6,7,24,29,[50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66]. For instance, Antczak et al [7] investigated the separation of succinic acid from fermentation broth with the use of a flat sheet NF membrane made of polyamide (active layer) and polysulfone.…”

The potential for nanofiltration (NF) in removing both relatively low molecular weight (MW) organic species and charged solutes from complex media is noteworthy. The main aim of the current work was to improve understanding of the separation mechanisms of fermentation broths components in the NF process. For this purpose, the experimental investigations were performed using the commercial polyamide NF270 membrane. The feed solution was ultrafiltered 1,3-propanediol (1,3-PD) broths. The separation results were analyzed and discussed in light of the detailed characteristics of both the membrane and the broth components. It has been noted that the membrane ensured the complete 1,3-PD permeability and significant rejection of some feed components. A thorough analysis showed that the retention of carboxylic acids was based on both the Donnan effect and sieve mechanism, according to the following order: succinic acid > lactic acid > acetic acid > formic acid. Indeed, acids retention increased with increasing charged acids ions valency, Stokes radius (rS) as well as MW, and decreasing diffusion coefficient (D). In turn, for ions, the following orders retention was determined: SO42− = PO43− > Cl− and Ca2+ > Na+ > NH4+ ~ K+. It indicated that the ions retention increased with increasing ions charge density, hydrated radius (rH), and hydration energy (Eh). It showed that the separation of the ions was based on the Donnan exclusion, sieving effect, and dielectric exclusion.

“…Here, the relationships between several explanatory variables (temperature, pressure, and concentration) and one or more response variables (rejection, energy consumption) were examined and regressed. A similar approach was taken by Alves et al [27] who found the optimal transmembrane pressure and temperature for the purification of xylitol using the surface response methodology. However, instead of ion rejections, only total salt rejection was considered and optimization was limited to a small-scale membrane system with a membrane area of 0.015 m 2 .…”

Nanofiltration is well suited to separate monovalent ions from multivalent ions, such as the separation of Li+ and Mg2+ from seawater, a potential lithium source for the production of lithium-ion batteries. To the best of our knowledge, there is no existing work on the optimization of a multi-stage membrane plant that differentiates between different ions and that is based on a validated transport model. This study presents a method for modeling predefined membrane interconnections using discretization along the membrane length and across the membrane thickness. The solution-diffusion–electromigration model was used as the transport model in a fundamental membrane flowsheet, and the model was employed to optimize a given flowsheet with a flexible objective function. The methodology was evaluated for three distinct separation tasks, and optimized operating points were found. These show that permeances and feed concentrations might cause negative rejections and positive rejections (especially for bivalent ions) depending on the ions’ properties and fluxes, thereby allowing for a favorable separation between the ions of different valence at optimized conditions. In an application-based case study for the separation of Li+ and Mg2+ from seawater, the method showed that under optimal conditions, the mol-based ratio of Mg2+/Li+ can be reduced from 2383 to 2.8 in three membrane stages.

When processing cattle and poultry, a large quantity of secondary slaughter products in the form of bone raw materials are formed in enterprises of the meat and poultry processing industry. Nowadays, its use is not optimal and rational. One of the promising directions of using bone raw materials in enterprises is production of finely ground meat and bone paste. The aim of this research was to study the chemical and mineral compositions, as well as the content of toxic elements in meat and bone paste from poultry and cattle bones obtained after complex grinding on a grinder and ultra-fine grinder. Chicken bone products (chicken necks, drumsticks, wings, breasts) and cattle costal and vertebral bones with residues of muscle tissue were used for investigation. The comparative analysis of the nutritional value of the meat and bone paste showed the following results: protein mass fraction was 18.5% in the meat and bone paste obtained from poultry bones, and 12.1% in the meat and bone paste obtained from cattle bones. The mass fraction of fat was two times higher in the meat and bone paste from poultry bones. As for the mineral composition, it has been established that meat and bone paste is a rich source of calcium: the calcium content was 1,654.02 mg/100g in the poultry meat and bone paste, and 5,318.13 mg/100g in the cattle meat and bone paste. In regard to the toxic element content, the normed values of lead and arsenic, cadmium and mercury were not revealed in the poultry and cattle meat and bone paste. The obtained meat and bone paste can be used for food purposes as a food additive in meat product manufacture, which will allow rational and economic use of bone raw materials in cattle and poultry processing.
