Historically, the most widely applied method of phosphorus removal has been chemical precipitation through the addition of iron or aluminium salts. Although more sustainable options, such as biological processes, are already being implemented at key sites, data shows that chemical removal is likely to remain an integral part of wastewater treatment—whether as the main method in small or problematic works or as a trim for meeting consents below 1 mg/L, not achievable through biological removal alone. All sewage treatment providers in the United Kingdom have developed asset standards (internal design and operation guidelines) for the design and management of chemical precipitation at existing works. However, the approach has not been consistent throughout the sector, with wide variations of criteria, brackets and rules of thumb. This paper collates and compares these approaches, looking at asset standards from most of the water companies in the United Kingdom. The methods stated in these standards have been applied for the sizing of chemical phosphorus removal on four simulated sites, to meet theoretical consents based upon the future discharge requirements set by the Environment Agency under the Water Industry National Environment Programme.","PeriodicalId":23753,"journal":{"name":"Water and Environment Journal","volume":"40 3-4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138525570","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}

Avoiding a water deficit through a supply-side approach has been the default strategy in Kuwait, yet this approach is unsustainable, associated with declining groundwater levels, and reliance on desalination that results in major carbon emission and environmental impact and that takes a large and growing share of oil revenues. In this study, we forecast household water demand in Kuwait to 2050 under a Business-As-Usual (BAU) scenario and evaluate the economic and environmental impacts. A spatial microsimulation, constrained by the national population projection of the Kuwait Institute of Scientific Research (KISR), was developed to overcome data limitations in forecasting household demand. Results show a 45% increase in water demand by 2050, to 664.1 million cubic metres (MCM), relative to the 2019 base year. Annual production costs increase from 1.39 billion USD in 2019 to 1.99 billion USD by 2050, whilst carbon emissions increase from 10.85 to 15.54 million tonnes/year. These results should alert policymakers to the potential impacts of the growing water demand and provide further support for water conservation action to reduce demand.","PeriodicalId":23753,"journal":{"name":"Water and Environment Journal","volume":"38 7","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138513158","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 findings of linear sweep voltammetry (LSV) and cyclic voltammetry (CV) demonstrated that applying CuO particles to carbon cloth (CC) significantly reduced the charge transfer resistance, resulting in improved electrochemical performance. In the batch experiment, the MFCs were conducted by applying different electrodes and Nafion-117 as a proton exchange membrane (PEM). X-ray powder diffraction (XRD), energy-dispersive X-ray analysis (EDAX) and scanning electron microscope (SEM) analyses were performed to study the development of metal oxide on the electrode surface. The MFC operating with the CC/CuO electrode achieved a maximum COD removal (74.6%), which was attained at the peak power output of 82.56 mW/m<sup>2</sup> and the greatest current density of 213.33 mA/m<sup>2</sup>, as indicated by the polarization curve data. In light of these findings, coating CuO on the CC anode promotes electron transfer, enhances the electrode's conductivity and increases its electrochemical surface area. In summary, the findings of this study hold significant implications for sustainable electricity production and remarkable effects on environmental quality, highlighting the strategic importance of the research approach and outputs in addressing global energy and environmental challenges.","PeriodicalId":23753,"journal":{"name":"Water and Environment Journal","volume":"40 4","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138513187","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}

A dataset of annual maximum precipitation consisting of 41 observation years (1970–2010) and 41 rain gauges was used. The results of the four old and new methods used to detect trends, Mann–Kendall (MK), Bravais–Pearson (BP), Spearman (SR) and innovative trend analysis (ITA), show good agreement. They revealed that a decrease in the trend of annual maximum precipitation was detected during the first period (1970–1992) with −44% (MK), −61% (BP), −68% (SR) and −76% (ITA). On the other hand, in the second period (1993–2010), a total shift occurred in which a significant increase in annual maximum precipitation trends was observed with +63% (BP), +34% (MK and SR) and +93% (ITA). These results show the ability of ITA to detect partial trends that the other three tests do not allow. Our results allow decision‐makers to properly design adaptation strategies in the face of the intensification of these extreme events.","PeriodicalId":23753,"journal":{"name":"Water and Environment Journal","volume":"111 34","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135138530","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}

A pilot‐scale hybrid treatment wetland (TW) equipped with local zeolite was employed, comprising a tidal flow TW and a horizontal subsurface flow TW. This system was efficient in treating pharmaceutical wastewater with removal efficiencies of 61.4%, 52.6%, 60.1%, and 61.9% for chemical oxygen demand, total phosphorus, total nitrogen, and NH 4 + ‐N, respectively. The final effluent met Jordanian standards for the reuse of treated wastewater in irrigation (Class B). Five pharmaceuticals, namely, enrofloxacin, ciprofloxacin, ofloxacin, lincomycin, and trimethoprim, demonstrated nearly completed removal (93.6–99.9%). Moderated removal performances (59.2–68.2%) were observed for two compounds, flumequine and sulfaquinoxaline. However, three pharmaceuticals, namely, carbamazepine, diclofenac, and sulfadimidine, showed limited removal performances (1.1–20.5%). This study supported the feasibility of using nature‐based solutions for treating pharmaceutical wastewater and highlighted that future studies are required to optimize this strategy for removing a broader range of pharmaceuticals.","PeriodicalId":23753,"journal":{"name":"Water and Environment Journal","volume":" 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135242588","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}

Then, we used semi‐structured interviews to collect the opinions of six respondents. Finally, the data were compiled and discussed by multivariate check analysis. The study found that although coastal resources can promote the rural economy, maintain community culture, build a comfortable living environment for the elderly and promote health and well‐being, they still affect the physical and mental health and well‐being of the elderly because of serious pollution, damage to the community environment and ecology, high prices and few leisure facilities. Therefore, reducing pollution, stabilizing prices, maintaining coastal biodiversity, controlling the consumption mechanism and providing a safe leisure environment will help promote the physical and mental health of the elderly, increase their enthusiasm and self‐confidence, and increase their sense of well‐being.","PeriodicalId":23753,"journal":{"name":"Water and Environment Journal","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135315805","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}

This leachate was initially electrochemically pre‐treated until the ratio of BOD 5 /chemical oxygen deman (COD) = 0.41, then an optimization of the parameters significantly influencing the biological degradation was carried. The results obtained after 13 h of biological treatment show the removal of 97% of the initial COD, with a mixed liquor composed of 700 mL of pre‐treated leachate and 300 mL of activated sludge, a dissolved oxygen concentration of 3.5 mg O 2 /L and a pH of 7, which allows the effluent to discharge directly into the environment. The conclusions of this work are promising because it was demonstrated that if the operating parameters are well controlled concerning these treatments, its sequence and the referred pre‐treatment, the treatment efficiency is very high to the point of direct discharge of the leachate. However, in future studies, the combination of the both processes should be more explored in order to reduce the treatment time and to scale‐up the process.","PeriodicalId":23753,"journal":{"name":"Water and Environment Journal","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135590440","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}
