“…It is composed of the active layer made from semiaromatic piperazine-based PA and the support layers from polysulfone (PS) and nonwoven polyester (PET) (Figure 4). Table 2 summarizes the physicochemical characteristics of the membrane, as given by the manufacturer, and several studies reported in the literature [31,33,[78][79][80][81][82][83][84][85][86]. During the investigation performed in the present study, the membrane surface was negatively charged since the pH of the fermentation broths (equal to 7) was higher than the isoelectric point of the membrane (equal to 4).…”

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.

“…Ion exchange resins having an affinity for cations or anions are widely used in water treatment and purification applications. They can directly remove phosphates, nitrates, perchlorates, arsenic, etc. − More importantly, the ion exchange resins can be recycled for industrial applications. Therefore, the ion exchange process using anion exchange resin is promising for synthesizing guanidine sulfate.…”

Polypentamethylene guanidine sulfate (PPGS), a cationic antibacterial agent with low metal corrosivity, was synthesized by replacing chloride ions in polypentamethylene guanidine hydrochloride (PPMG) with sulfate ions using anion exchange resins. The results of corrosion experiments at high temperatures and in an aqueous solution suggested that PPGS exhibited better corrosion resistance than PPMG. The synthesized PPGS exhibited lower thermal stability and degradation occurred through the removal of sulfate groups. It showed strong intrinsic antimicrobial characteristics, which could change the morphological structure and rupture cell membranes. Furthermore, the minimal inhibitory concentrations of PPGS against Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and Candida albicans were approximately 8, 2, 16, and 12 ppm, respectively. Molecular simulations indicated that the positive charges accumulated on the PPGS surface can provide the driving force to attract bacteria with a negative charge on the cell membrane's phospholipid layer.

“…Membrane bioreactors and modules for dialysis, electrodialysis (ED), and capacitive deionization contain these membranes. Already, these membrane technologies are promising for the processing of fermentation broths or waste fermentation effluent [ 1 , 2 , 3 , 4 ], agricultural, industrial streams and natural waters [ 5 , 6 , 7 , 8 , 9 ], the selective separation of various acids [ 10 ]; tartrate stabilization of wine; demineralization of milk whey; reagent-free correction of the pH of juices and wines [ 11 ], or conversion of salts to polybasic acids and vice versa [ 12 , 13 ]. Citrates [ 2 , 11 , 14 , 15 ], malates [ 10 , 14 ], tartrates [ 13 ], oxalates [ 7 ], chromates [ 16 , 17 ], vanadates [ 18 ], and sulfates [ 19 ] are the most common objects of the application of processes in which ion-exchange membranes are involved.…”

Phosphates Transfer in Pristine and Modified CJMA-2 Membrane during Electrodialysis Processing of NaxH(3−x)PO4 Solutions with pH from 4.5 to 9.9

et al. 2023

Phosphate recovery from different second streams using electrodialysis (ED) is a promising step to a nutrients circular economy. However, the relatively low ED performance hinders the widespread adoption of this environmentally sound method. The formation of “bonded species” between phosphates and the weakly basic fixed groups (primary and secondary amines) of the anion exchange membrane can be the cause of decrease in current efficiency and increase in energy consumption. ED processing of NaxH(3−x)PO4 alkaline solutions and the use of intense current modes promote the formation of a bipolar junction from negatively charged bound species and positively charged fixed groups. This phenomenon causes a change in the shape of current–voltage curves, increase in resistance, and an enhancement in proton generation during long-term operation of anion-exchange membrane with weakly basic fixed groups. Shielding of primary and secondary amines with a modifier containing quaternary ammonium bases significantly improves ED performance in the recovery of phosphates from NaxH(3−x)PO4 solution with pH 4.5. Indeed, in the limiting and underlimiting current modes, 40% of phosphates are recovered 1.3 times faster, and energy consumption is reduced by 1.9 times in the case of the modified membrane compared to the pristine one. Studies were performed using a new commercial anion exchange membrane CJMA-2.
