This research compares experimentally a hybrid humidification-dehumidification system with a thermoelectric cooler addition in view of maximizing water vapor condensation as well as fresh water output. Air humidification was supported by an evaporative pad, while dehumidification was achieved using a TEC module powered at varying voltages. Experiments were conducted under three ambiances with varied temperature as well as relative humidity levels, while air velocity ranged between 1.5 as well as 2.5 m/s with thermoelectric cooler voltage between 6 and 12 V. Performance indicators such as humidification effectiveness, water productivity, recovery ratio as well as power consumption, as well as coefficient of performance were among parameters under study. Results demonstrate that humidification effectiveness takes place at around 66 % at low air velocity, with water productivity increased three times with increased thermoelectric cooler voltage with increased output from 14 mL/h at 6 V to 42 mL/h at 12 V under optimal air velocity. Recovery ratio doubled in similar trends with increased moisture recuperation. Contrarily, increased thermoelectric cooler voltage resulted in a 60 % decrease in system work rate as in waters produced per watt-hour with increased power consumption. Coefficient of performance levels ranged between 2.3 and 3.1 at low voltages but decreased as high as 70 % at 12 V, exhibiting trade-off between increased cooling effect as well as increased power consumption. These reveal considerable implications in optimizing thermoelectric cooler voltage as well as air velocity in balancing fresh water output with work rate in maximizing cost-effective as well as sustainable atmospheric water harvesting measures.</div></div>","PeriodicalId":299,"journal":{"name":"Desalination","volume":"616 ","pages":"Article 119347"},"PeriodicalIF":9.8,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144913395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the removal efficiencies of SS, COD, NH₃-N, TN, and TP in EC-CM reached 99.5 %, 80.8 %, 27.8 %, 35.1 % and 99.7 %, respectively, fully meeting the re-utilization standards in China. However, EC-CM only slightly improved the normalized flux compared to CM alone, suggesting that EC-CM did not effectively alleviate membrane fouling. To further investigate the membrane fouling mechanisms in EC-CM, comparative studies were conducted using 120 min of CM alone (CM-120), 60 min EC-CM and 60 min CM alone (EC-CM-60 + CM-60), and 120 min of EC-CM (EC-CM-120). The results indicated that EC could sharply aggregate particles into micro flocs and effectively remove fulvic acid-like and humic acid-like substances in organic matter. This process shifted the initial membrane fouling mechanisms from standard and complete blockage in CM alone to complete blockage in EC-CM. During this period, the normalized flux of EC-CM decreased more rapidly than that of CM alone due to larger interfacial energy of micro flocs-CM, leading to more severe chemical irreversible fouling. As the EC process continued, the micro flocs gradually evolved into larger flocs, which accumulated on the membrane surface and formed a cake layer, thus transitioning the fouling mechanism to cake filtration. Due to lower interfacial energy between flocs, EC-CM exhibited less chemical reversible fouling compared to CM alone. Furthermore, larger flocs with lower fractal dimension would form a looser cake layer compared to primary particles, leading to a reduction in physical reversible fouling. Based on the membrane fouling mechanisms mentioned above, the normalized flux was improved to 0.72 by optimizing the operational mode of EC-CM. These findings provide a promising alternative for rainwater re-utilization and offer valuable insights into the membrane fouling mechanisms in EC-CM.</div></div>","PeriodicalId":299,"journal":{"name":"Desalination","volume":"616 ","pages":"Article 119350"},"PeriodicalIF":9.8,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144926116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, such demonstrations have been scarce, and the critical parameters affecting printing uniformity and membrane performance remain elusive. In this study, we developed a 10-nozzle electrospray system for large-area PEM membrane production through layer-by-layer printing with polyethyleneimine (PEI) and poly(sodium 4-styrene sulfonate) (PSS). We thoroughly evaluated the key parameters of electrospray droplets including size, flight and evaporation time. Additionally, we revealed that misalignment of nozzles and irregular Taylor cones deflected electrospray droplets, leading to their positional shift and ultimate uneven printing. The nozzles' reciprocating motion covering twice the nozzle spacing improved printing uniformity, with 93 % of the area showing a deviation within ±20 % of the average. Our system achieved an areal deposition mass of 0.78 g (PEI + PSS)/m² and an impressive deposition efficiency of 95 %, attributed to controlled droplet trajectories. In addition, we discovered that total printing duration within 1 h was critical to prevent substrate drying and preserve membrane water permeability. Finally, we successfully produced a large-area PEI/PSS membrane measuring 40 × 60 cm² in 1 h. The membrane exhibited a water permeability of 9.8 ± 1.3 L∙m⁻²∙h⁻¹∙bar⁻¹ and a PEG (1000 Da) rejection of 47 % ± 7 %, with performance deviations below 15 % across the membrane.
