Wastewater generated from N-methylpyrrolidone (NMP) manufacture was used as electron donor for denitrification in tertiary treatment. The organic components of NMP wastewater were mainly NMP and monomethylamine (CH3NH2), and their biodegradation released ammonium that was nitrified to nitrate...

In recent years, problems related to the adequacy of existing water resources have arisen due to issues such as population growth, rapid urbanization, industrialization, and climate change. In the study, by comparing the agricultural productions with wastewater and well water, 2 hypotheses have...

We investigate the effects of sewer access on neighborhood characteristics in developing world cities. Because it is more difficult to move sewage uphill than downhill, otherwise similar neighborhoods on opposite sides of drainage basin divides may face different costs of sewer access. We...

It has long been understood that public utilities, and especially sewers, play a powerful role in shaping patterns, rates, and forms of urban development. But decisions about whether and where to build this “growth-shaping” infrastructure are largely left to local communities, who frequently...

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...

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...

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,...

This study modelled and optimized biomass and lipid accumulation using mix wastewater for the cultivation of Chlorococcum sp. The simplex lattice mixture design was used to optimize complementary wastewater mixture ratio (25:75, 50:50, 100:0) of dairy (DWW) and paper-pulp (PWW) wastewater. The...

Wastewater and pollution management issues are usual negative externalities in the pursuit of economic development. This is true in the Philippines where industrial and domestic refuse often end up in tributaries and major waterways, sometimes even contaminating groundwater due to improper...

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...

Diese Veröffentlichung stellt eine von sechs Analysen sektorenübergreifender Herausforderungen für Wasser-Governance dar, die als Teil des STEER-Forschungsprojekts durchgeführt wurden und deren Resultate in separaten Analysen und Stellungnahmen vorliegen. Der Abbau von Mineralien und...

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...

Canadian municipalities are hurting housing affordability by imposing expensive water charges on development, according to a new report published by the C.D. Howe Institute. In “Hosing Homebuyers: Why Cities Should Not Pay for Water and Wastewater Infrastructure with Development Charges”,...

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...

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...

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...

The objective of this paper is a theoretical and empirical analysis and evaluation of the role, importance and opportunities of the water-sewage-sludge industry in the implementation of the circular economy. To realize this objective, a review of both the literature and the EU strategic...

Das Ziel dieser Arbeit war, mithilfe von Stoffstrom- und Nutzwertanalysen sechs verschiedene technische Wasserinfrastruktursysteme in den Städten Hamburg und Qingdao (China) bezüglich der Stoffströme Wasser, Energie und Nährstoffe, auf häuslicher Ebene bzw. Siedlungsebene miteinander zu...

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...

Wastewater use in agriculture is a growing practice worldwide. Drivers include increasing water stress, in part due to climate change; increasing urbanization and growing wastewater flows; and more urban households engaged in agricultural activities. The problem with this trend is that in...

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...

Monitoring illicit drug use is difficult because of the hidden and complex nature of drug-using behaviours. 'Wastewater analysis', or 'wastewater-based epidemiology', holds promise for complementing established methods of drug use measurement. Wastewater in municipal water treatment plants...

"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...

"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...

Just a few years after Congress passed the 1972 CWA Amendments, former EPA Administrator Russell Train wrote: "One of the major challenges to our society, and specifically to our states and localities, is to deal e8ectively with the issues of growth. These issues will involve an increasing shift...
