However, VOCs exhibited different behavior. VOCs emerged as a potential contributor to odor sensation, with elevated levels observed during specific morning hours, which intensified when the VF CW was not operational. Nevertheless, the results suggest that the VF CW treatment has a limited impact on the production of gases responsible for odor sensation.

They are widely used in various industrial processes and products, and as a result, PFAS pollution is pervasive and has led to persistent contamination of surface and groundwater sources. Due to the adverse impact of PFAS exposure on health, there have been growing concerns among the public, the scientific community, and regulatory bodies, and treating water to an adequate level is essential. Nanofiltration (NF) and reverse osmosis (RO) are two of the candidate technologies for separating PFAS from water. NF and RO systems are easy to operate and require little use of chemicals. In contrast, other water treatment technologies (<em>e.g.</em>, chemical oxidation, adsorption, ion exchange, and photocatalytic degradation) are often unsatisfactory due to slow reaction kinetics, generation and release of harmful by-products, or high operating costs. Despite the advantages of NF and RO, a concentrated residual stream is produced which contains high levels of PFAS. This concentrate, which typically accounts for 10 to 20% of the feedwater volume and is 5 to 10 times more concentrated with PFAS, must be managed or further treated appropriately to prevent environmental contamination. In this review, the NF/RO systems for the treatment of PFAS-contaminated water are discussed, focusing on the factors that affect their effectiveness and the mechanisms by which they remove PFAS. Also, advances in NF/RO membranes and systems as well as technical challenges at present are discussed along with an introduction to a total management plan for concentrated residual streams using a novel combination of NF/RO processes coupled with other state-of-the-art methods.</p>","PeriodicalId":75,"journal":{"name":"Environmental Science: Water Research & Technology","volume":" 9","pages":" 1994-2012"},"PeriodicalIF":3.5,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141525875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zeolite adsorption is an effective method for calcium removal. However, treated water requires additional filtration to remove suspended solids, which uses energy under traditional methods. Considering applications at sites where electricity is unavailable, this study removed calcium from water using zeolite adsorption and gravity-driven membrane (GDM) filtration. Four zeolite types were assessed: powdered (P1 and P2), bead-shaped (B) and granular (G). The properties of the zeolites significantly affected calcium removal and GDM filtration performance. Zeolites with low Si/Al ratios (high Al content) exhibited high Ca removal because negatively charged lattice sites were created by replacing Si with Al. P1 and B with Si/Al ratios of 1.40 and 1.49, respectively, exhibited high Ca-removal efficiencies of 92.6% and 99.8%. In contrast, P2 and G with high Si/Al ratios from 4.71–5.35 showed lower removal efficiency of 29.8–43.7%. The average sizes of P1, P2, B, and G were 9.68, 5.73, 2134, and 3639 μm, respectively. At similar Si/Al ratios, smaller particles exhibited faster adsorption rates. However, as the zeolite size decreased, the GDM flux decreased. During GDM filtration after zeolite adsorption, the permeate flux of water treated with large B and G zeolites was higher than that of water treated with small P1 and P2 zeolites. Finally, the zeolites were evaluated based on three criteria: Ca removal, GDM water flux, and price, which provides useful guidance for selecting appropriate zeolites.</p>","PeriodicalId":75,"journal":{"name":"Environmental Science: Water Research & Technology","volume":" 10","pages":" 2357-2365"},"PeriodicalIF":3.5,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141532154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective was to understand how effectively DWTPs can adapt to seasonal changes and compare how optical and mass spectrometry methods detected these changes. In addition to bulk DOM analysis, this work focused on excitation–emission matrix (EEM) fluorescence including parallel factor (PARAFAC) analysis, and molecular level non-target analysis by Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). Overall, seasonal variability of raw water DOM composition was small and explained primarily by changes in the contributions of DOM with aromatic and phenolic moieties, which were more prevalent during spring in two surface water sources as indicated by absorbance measurements at 254 nm, computed specific ultraviolet absorbance (SUVA) and phenol concentrations. These changes could be balanced by coagulation, resulting in seasonally stable DOM characteristics of treated water. While EEM fluorescence and PARAFAC modelling effectively revealed DOM fingerprints of the different water sources, FT-ICR MS provided new insights into treatment selectivity on DOM composition at the molecular level.
