Pharmaceutical residues are released in the aquatic environment due to incomplete removal from wastewater. With the presence of multiple chemicals in sewage waters, contaminants may adversely affect the effectiveness of a wastewater treatment plant (WWTP). In certain cases discharged metabolites...

Abstract: The contamination of soil and water with heavy metals, such as cadmium and lead, is a serious problem. Previous remediation techniques are not effective when these two toxic elements are immobilized. Microbial induced carbonate precipitation has been proven to effectively remove heavy...

The effect of anaerobic sludge digestion on the isolation of DNA and clean-up efficiency of obtained DNA isolates was studied. Sludge samples were taken from a mesophlic full-scale, and batch digesters operated under mesophilic and thermophilic conditions. Declines over 90% in the extraction...

Microwave-assisted Fenton process over a high microwave-responsive catalyst (Fe3O4-BiOCl) was developed to environment-friendly treat toluene nitrification wastewater. The morphology, composition and magnetic recovery of the prepared catalyst were analyzed using various analytical instruments....

Wastewater-based epidemiology (WBE) approach for COVID-19 surveillance is largely based on the assumption of SARS-CoV-2 RNA shedding into sewers by patients. Recent studies found that SARS-CoV-2 RNA concentration in wastewater (CRNA) could not be accounted by the fecal shedding alone. This study...

Incorporating uranium into magnetite crystal from wastewater to limit its mobility have been proposed to the long-term remediation of radioactive contamination. Unfortunately, this process is accompanied by reduction or surface adsorption, which significantly reduces the incorporation capacity...

Cu(II)-EDTA is a highly stable typical metal-organic complex in a wide pH range (3.0-12.0) and difficult to deeply purify Cu(II) by conventional precipitation methods. In this study, Fe(III) replacement/diethyldithiocarbamate (DDTC) precipitation combined process was proposed as a promising...

With the increase in shipping density, the risk of wastewater generated by ships in coastal areas has raised much attention. The present study proposes a model to estimate the spatiotemporal distribution of wastewater including greywater and sewage generated by ships in coastal areas. The model...

Solar-driven interfacial evaporation is considered a promising solution to water pollution and water shortages, potentially reducing heat loss and improving energy conversion efficiency. However, the current photothermal films used for solar-driven interfacial water evaporation have some issues...

An increased energy recovery efficiency can be obtained from biomass waste due to coupling hydrothermal carbonation (HTC) with anaerobic digestion (AD). This study focused on optimizing the total energy yield (TEY) from sewage sludge (SS) and pinewood sawdust (PS) in co-HTC-AD coupling process,...

D0 bleaching wastewater from E. globulus Kraft pulping industry was treated by Fenton and photo-Fenton processes. The aim was to optimize the operational conditions for adsorbable organic halides (AOX) removal, namely oxidant concentration, [H2O2], catalyst concentration, [Fe2＋], and treatment...

This Briefing Paper presents one of six analyses of cross-sectoral coordination challenges that were conducted as part of the STEER research project and on which separate Briefing Papers are available. The extraction of minerals and metals comes with a large water footprint, both in terms of...

Privatization of a public good (the management of sewage treatment centers in Dakar, Senegal) leads to an increase in the productivity of downstream sewage dumping companies and a decrease in downstream prices of the services they provide to households. We use the universe of legal dumps of...

Properly managed sanitation systems and improved wastewater treatment are important for safeguarding environment and enhancing sustainable livelihoods in vast areas of South and Southeast Asian countries. Recovering nutrients and energy from organic waste and wastewater is an effective option...

Currently, the constantly growing problem in the municipal economy is the management of sewage sludge. According to the law, it is the local government that is responsible for the utilization of sewage sludge and is obliged to select optimal technologies, obtain funds and convince the community...

Public-private partnership (PPP) contracts are frequently used in the provision of public services. One of the key points to consider in these contracts (and from which much of its convenience derives) is the allocation of risks to the party that has the best capacity to avoid them or, if they...

"This book is the first comprehensive effort to bring together Water, Food Security and Nutrition (FSN) in a way that goes beyond the traditional focus on irrigated agriculture. Apart from looking at the role of water and sanitation for human wellbeing, it proposes alternative and more locally...

"The second edition provides students with a comprehensive overview of natural processes associated with water and the modifications of these processes by humans through climate change and land management, water-related health issues, engineering approaches to water and socio-economic processes...

Under increasing demand for water, fertilizer and energy, waste and wastewater treatment can be potential options for considerably enhancing not only the supply of these valuable economic assets but also for improving sanitation and ecological conditions. Effluents and treated wastewater are...

Despite public approval from the Danish Environmental Protection Agency (Miljøstyrelsen), farmers have proven reluctant to accept wastewater sludge as a source of fertilizer. They are in fact still being paid for accepting it. Based on interviews with key stakeholders, a review of the...

Public-private partnership (PPP) contracts are frequently used in the provision of public services. One of the key points to consider in these contracts (and from which much of its convenience derives) is the allocation of risks to the party that has the best capacity to avoid them or, if they...

This paper analyzes the relationship between intermunicipal cooperation and efficiency of public service provision. The organizational arrangements, including self-provision, joint pro-vision or contracting, affect politicians’ and bureaucrats’ incentives as well as internal transaction...

The English and Welsh water and sewerage industry is characterised by indivisible capital which has a long service life. Previous studies of efficiency of the English and Welsh water and sewerage industry take a static framework, assuming all inputs can be adjusted instantaneously. This paper...

The conclusions of Advocate General Jääskinen in the matter of the infringement proceedings against Germany, regarding the scope of the term "water services" in Article 9 of the Water Framework Directive, are now available. In these he considers that the action brought by the Commission...

There is an urgent need to provide practical guidelines for Chinese decision makers and officials to better understand the key issues and constraints related to rural wastewater management and to identify feasible solutions and tools to improve the performance and sustainability of these...

Developing countries are faced with a substantial and persistent infrastructure deficit. Climate change complicates this challenge, affecting the way we design and manage infrastructure (defined here as transport, power, water and sanitation) and increasing costs. But all is not negative:...
