Slow sand filtration is a common technology providing potable water in rural households across Latin America, Asia and Africa. Two PVC household slow sand filters (HSSF) were operated in continuous (C-HSSF) and intermittent (I-HSSF) flow modes for eight consecutive months. A non-woven blanket was installed on the fine sand top to facilitate cleanin...

This study aimed to treat river water for domestic water supply purposes in the South of Vietnam by photocatalysis. Since the pre-treatment of traditional coagulation was effective in removing turbidity and other pollutants, the photocatalytic step was mainly applied for the removal of organics and disinfection of pathogens. The titanium nanotubes ...

Mature and old-growth forests (MOG) of the conterminous United States collectively support exceptional levels of biodiversity but have declined substantially from logging and development. National-scale proposals to protect 30 and 50% of all lands and waters are useful in assessing MOG conservation targets given the precarious status of these fores...
The aims of this study were to determine the radon concentration in natural mineral and tap water and to estimate the resulting ingestion doses received by adults. Physical-chemical characteristics of water samples have also been investigated. In the last years have been an increase of water consumption of both, natural mineral and tap, many source...
Ensuring the long-term functionality of community-managed rural water supply systems has been a persistent development challenge. It is well established that the technicalities of keeping the systems going are impacted by complex political, social, financial, and institutional challenges. While the shift to federal, three-tiered governance allocate...

In Apuseni Mountains (North-Western Romania), many of the inhabitants live in rural communities with limited or no access to the centralized and controlled water supply. This study assesses the microbiological quality of six karst spring waters from Bihor County used by rural communities as drinking water sources. Twenty-four water samples collecte...

Drinking water distribution systems are critical infrastructure that protect public health by ensuring safe water is transported from centralized treatment facilities to consumers. While growth of bacteria, such as opportunistic pathogens, in distribution system infrastructure is well established as a detriment to water quality, little is known abo...

The goal of this research is to apply an electrocoagulation process in continuous flow for the defluoridation of drinking water. Two sampling sites were studied, Temascalcingo (T), Mexico state and Jerecuaro (J), Guanajuato, with fluoride (F-) concentrations above the norms (2.3 mg L-1 and 4.5 mg L-1, respectively). In addition, a second Temascalci...

Household Water Treatment and Safe Storage (HWTS) are recommended to supply the demand for drinking water in communities without conventional water supply systems. However, there is a lack of long-term laboratory studies regarding such technologies. We evaluated the contributions of each step of a multi-barrier system with pretreatment (sedimentati...
Granulierte Aktivkohlen (GAK) leisten bei der Trinkwasseraufbereitung einen großen Beitrag zur adsorptiven Spurenstoffentfernung. Aufgrund der energie- und CO2-intensiven Herstellung und einer zukünftig möglichen Rohstoffverknappung sollten Wasserversorger eine bestmögliche Ausnutzung dieses Aufbereitungsstoffes anstreben. Die GAK-Reaktivierung ist...
