However, the fouling caused by dissolved organic matter (DOM) is still a challenge to the long-term operation of ion-exchange membranes in ED, and the mechanism of this fouling has not been well studied regarding these compounds’ molecular size. Taking pig manure digestate as an example, this study utilized an ultrafiltration-ED design to fractionate the DOM into many different ranges of molecular size and then assessed the molecule size-specific DOM-fouling to ED membranes. The results showed that the fouling to the anion-exchange membrane (AM) was significantly influenced by molecular size, while the cation-exchange membrane was antifouling over full molecular size ranges. The DOM with a molecular size of smaller than 10 kDa, accounting for 9.1% of the total DOM in digestate, was found to mainly cause AM deterioration. In particular, the DOM smaller than 1 kDa migrated into the interior of AM, thus increasing the membrane resistance by 25.7% and decreasing the ion exchange capacity by 3.5%. The DOM with molecular size in the range of 1–10 kDa caused the fouling in the zone of 0–100 μm depth from the membrane surface. Meanwhile, the DOM with molecular size larger than 10 kDa did not cause obvious irreversible fouling. For instance, the DOM being larger than 0.1 μm, accounting for 75.2% of the total organic matter in the digestate, did not cause irreversible membrane fouling. These results indicate that attentions should be paid to the fouling caused by DOM with small molecular size of less than 10 kDa.</p></div>","PeriodicalId":368,"journal":{"name":"Journal of Membrane Science","volume":"685 ","pages":"Article 121974"},"PeriodicalIF":9.5,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0376738823006300/pdfft?md5=a025c2dce857c27389758e3800d7438b&pid=1-s2.0-S0376738823006300-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44691046","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study therefore examines the independent and concomitant role of temperature and pressure in determining CO₂ mass transport, and selectivity, within microporous and nonporous HFMC. At low solvent temperatures, higher CO₂ flux was achieved which indicates that solvent solubility is more critical than CO₂ diffusivity to enhancing mass transport. Low temperatures also favoured mass transfer within the microporous membrane, explained by the reduction in solvent vapour pressure which limited pore wetting by condensation. In contrast, the nonporous membrane exhibited poorer mass transfer at low temperatures due to a decline in dense polymer permeability. Crucially in this study, neither wetting of the microporous membrane or plasticisation of the nonporous membrane were observed following pressurisation. Consequently, CO₂ flux increased in proportion to the applied pressure for both membrane types, emphasising the critical role of pressurisation in augmenting process intensification for biogas upgrading which is typically facilitated at pressures of 7–10 bar. Resistance-in-series analysis illustrated how pressurisation reduced gas-phase resistance, and subsequently enhanced selectivity. Consequently, an outlet gas quality of 98% methane could be achieved within a single microporous module at 4.5 bar, meeting the industrial standard for biomethane whilst reducing solvent requirements, separation energy and methane losses. Comparable behaviour was observed during pressurisation of the nonporous membrane, but with a less significant benefit to CO₂ mass transfer and selectivity, ostensibly due to the resistance imparted by the dense polymer. When considered collectively, low solvent temperature and high gas pressure enhance process intensification subsequently reducing process size (e.g., membrane area) and separation energy, while also advancing selectivity to deliver a gas product at the composition required for biomethane with minimum methane losses, which are critical factors in demonstrating microporous HFMC as an industrially competitive solution for biogas upgrading.</p></div>","PeriodicalId":368,"journal":{"name":"Journal of Membrane Science","volume":"685 ","pages":"Article 121967"},"PeriodicalIF":9.5,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0376738823006233/pdfft?md5=0fc6bd72afe746870cfbda1ae74f2ff3&pid=1-s2.0-S0376738823006233-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43886887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
