The issue of sludge utilization from wastewater treatment in agriculture is an important socio-economic and environmental problem in the European Union (EU) and Bulgaria. It is becoming topical issue along with constantly growing amount of produced wastewater treatment sludge, deficiency of...

Randomized controlled trials (RCTs) of water treatment are typically powered to detect effects on caregiver-reported diarrhea but not child mortality, as detecting mortality effects requires prohibitively large sample sizes. As a result, water treatment is often not included in lists of...

U.S. exports of water filtration and purification equipment reached $1.8 billion in 2011, increasing by 20 percent since 2007 and by 110 percent since 2002, with Asia the leading export destination. Due to insufficient availability of water, rising incidence of extreme weather events, and...

Improving the efficiency and sustainability of water treatment technologies is crucial to reduce energy consumption and environmental pollution. Solar-driven devices have the potential to supply off-grid areas with freshwater through a sustainable approach. Passive desalination driven by solar...

This research paper was released on 18 March 2020 and it examines the policy and implementation frameworks currently governing the urban water sector to identify where there may be impediments to the adoption of Integrated Water Cycle Management (IWCM). IWCM refers to the joint management of...

Households in developing countries face an enormous set of health risks from using contaminated water sources. In 2014, a group of 512 households relying on unimproved water, sanitation and hygiene practices in the Greater Accra region of Ghana were randomly selected to participate in the...

Water treatment process produces great amount of sludge. According to growing interest in sustainable development and environment protection, sludge management problem should be taken into consideration. Accordingly, its recovery, recycling and reuse are optimal solutions for Water Treatment...

The ever-growing population of India, along with the increasing competition for water for productive uses in different sectors - especially irrigated agriculture and related local water systems and drainage - poses a challenge in an effort to improve water quality and sanitation. In rural and...

This is a rejoinder to a comment written by Cutler and Miller on our recent paper, "Public Health Efforts and the Decline in Urban Mortality" (IZA DP No. 11773), which reanalyzes data used by Cutler and Miller to investigate the determinants of the urban mortality decline from 1900 to 1936. Two...

Each year, around 500,000 children under 5 die from diarrhea, making it the third-leading cause of death in this age group. More than 80 percent of these deaths are attributable to unsafe drinking water. Drinking water can be made safe through dilute chlorine solution, but take-up of this...

The decade from 2010 to 2019 marked a significant turning point in China's history of environmental regulation and pollution. This article describes the recent trends in air and water quality, with a focus on the five years since China declared a "war on pollution" in 2014. It summarizes the...

Water is an essential commodity and in many instances, needs to be treated before it becomes fit for consumption either by humans or industries. Water treatment thus is one of the most common processes that is used across many sectors like municipalities, power plants, petrochem plants and...

"Regional water security around the world is at risk from climatic and non-climatic challenges, including extreme weather events, rapid population growth and urbanisation, economic growth and rising income levels, ageing infrastructure, and increased demand for energy and food, impacting water...

The transition from laboratory research to pilot scale trials can be challenging for novel water treatment technologies. This transition is even more complex for technologies intended for use in a developing country context due to cultural, infrastructural, financial and capacity related...

Using data on 25 major American cities for the period 1900-1940, we explore the effects of municipal-level public health efforts that were viewed as critical in the fight against food- and water-borne diseases. In addition to studying interventions such as treating sewage and setting strict...

Ziel des Beitrages ist, anhand des Beispiels der Mikrofiltrationstechnologie die Genese von einer Hochtechnologie zu einer Alltagstechnologie über die im Markt erfolgreichen Artefakte und deren Rückwirkung auf die sie produzierenden Unternehmen nachzuzeichnen. Dabei handelt es sich um ein...

"This book explores the fundamentals of membrane process, membrane fabrication and characterization, and membrane processes and operation. It also examines the application of membrane technologies in water and wastewater treatment in rural regions"--

The aim of the present study was to assess the possibility of use economic analysis to compare selected filter beds used in water treatment plant. There were considered selected masses which are commonly used for removal iron and manganese from the groundwater. Water purification with these...

Since the 1972 U.S. Clean Water Act, government and industry have invested over $1 trillion to abate water pollution, or $100 per person-year. Over half of U.S. stream and river miles, however, still violate pollution standards. We use the most comprehensive set of files ever compiled on water...

Although previous research has demonstrated the health benefits of water treatment programs, relatively little is known about the effect of water treatment on education. This paper examines the educational benefits to rural youth in China of a major drinking water treatment program started in...
