Direct membrane filtration (DMF) using ultrafiltration provides a low-energy alternative for recovering organics, which are utilized for energy recovery through anaerobic digestion (AD). However, DMF faces challenges from membrane fouling and elevated dissolved organics in the permeate. To address these issues, this study implements biological contact tank pre-treatment before DMF, with a short hydraulic retention time (HRT) of 60 min. This pre-treatment selectively removes 62% of dissolved organics without compromising the recovery of suspended or colloidal organic matter and enhances permeate quality by 40% in terms of chemical oxygen demand (COD). The DMF system without pre-treatment exhibits 1.84 times higher irreversible pore-blocking membrane resistance, with higher foulant concentrations per membrane unit area (up to 2.54 times) and enzymatic activity (up to 3.04 times). The recovered organics undergo AD, yielding methane up to 336 ± 23 mL-CH<sub>4</sub>/g-VS, making the DMF system net energy positive. Life cycle assessment (LCA) reveals that the DMF system has lesser environmental impacts than the conventional system in 10 out of 18 impact categories.</p>","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 8","pages":""},"PeriodicalIF":6.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144909907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, achieving effective separation often requires post-processing to enhance membrane wettability or modify pore size, which can reduce productivity. In this study, a simple method is proposed for pore size control via mechanical compression of electrospun membranes. Polystyrene (PS) fibrous membranes (PFMs) are fabricated through electrospinning and subsequently compressed using a hand tool, reducing the membrane thickness by ≈87%. The proportion of pores smaller than 10 µm in diameter increase from 4.8% before compression to a maximum of 45.6% after compression. While the uncompressed membrane allowes sub-10-µm water droplets to pass through, the compressed membrane effectively blocked them. Due to the oleophilic nature of PS, oil permeation occurres rapidly via capillary action, while water droplets are retained within the membrane's internal pores, facilitating continuous demulsification. By combining electrospinning with mechanical compression, the optimized compressed PS fibrous membrane (CPFM) successfully separated water-in-oil emulsions under gravity, achieving a separation flux of 606 L m<sup>−2</sup>h<sup>−1</sup> with an oil purity of over 99.85%.

Lightweight oven-dried foams suitable for rigid thermal insulation are produced using four types of wood residue and can be made using ocean water instead of ultrapure water. The bio-based content in the foam can be increased by partially/fully replacing the polymer binder with mechanical pulp or using a biosurfactant. For the 15 foams produced with slightly modulated compositions, the densities are low (90–130 kg m<sup>−3</sup>), the thermal conductivities are low (38–45 mW m<sup>−1</sup> K<sup>−1</sup>), and many meet ASTM insulation standards for compressive strength. Pilot plant scaling produced large-scale (100×50×4 cm) foam boards. The structure-property relationships elucidated offer new guidelines to optimize foam performance by matching microparticle size to bubble size, having a distribution of microparticle lengths, and preserving wood's natural macroporous character.
