BACKGROUND Safe drinking water is critical for health. Household water treatment (HWT) has been recommended for improving access to potable water where existing sources are unsafe. Reports of low adherence to HWT may limit the usefulness of this approach, however. METHODS AND FINDINGS We constructed a quantitative microbial risk model to predict gains in health attributable to water quality i...

Effluent from the textile industry contains toxic compounds. These compounds contaminate the surface water, thereby making it unfit for irrigation and drinking. Since farmers use water from the rivers for agricultural purposes and the residents of the town, use both the surface and underground water from the same area as potable water, it is quite unsafe to discharge this effluent into water bo...

-The aim of the Proposed Project is a Microcontroller based Low-Cost Sensor Network for Real-Time Monitoring and Contamination Detection in Potable and nonPotable Water Distribution Systems and also updates the information to the consumers and concerned authorities by using GSM module. In the existing system, it is just monitor the water level and electrical conductivity manually (off-line) and...

In this study, a new proposed multi-generation system as a promising integrated energy conversion system is studied, and its performance is investigated thermodynamically. The system equipped with parabolic trough collectors and biomass combustor to generate electricity, heating and cooling loads, hydrogen and potable water. A double effect absorption chiller to provide cooling demand, a proton...

ITT (now Xylem) Water & Wastewater Leopold Business Unit has provided dissolved air flotation (DAF) systems to the municipal potable water treatment market since early 1990s. This chapter discusses DAF process and high-rate Clari-DAF® system design criteria. It also presents data from pilot studies case of full-scale plants in operation showing expected performance through system.

Urbanisation and the subsequent increase in impervious land use generate increased urban stormwater which can be recycled viamanaged aquifer recharge (MAR) to supplement more traditional surface or ground water supplies. This paper compares the quality of stormwater from two urban catchments in South Australia to assess the risks, in accordance with the Australian Guidelines for Water Recycling...

background : collection and storage of roof rain water have been practiced for long time ago in iran and many other countries. water of cisterns is usually used as potable water. in golestan province many of rural torkman residents reservoir the most part of their potable water from roof rain in cisterns. in this province there are over 2600 cisterns. methods : to study the water quality, micro...

Chlorine is widely used in public water supplies to provide a disinfection barrier. The effect of chlorine disinfection on the water-borne pathogen Burkholderia pseudomallei was assessed using multiple techniques. After exposure to chlorine viable bacteria were undetectable by conventional plate count techniques; however, persistence of B. pseudomallei was verified by flow cytometry and bacteri...

Photocatalysis is a promising method for the disinfection of potable water in developing countries where solar irradiation can be employed, thus reducing the cost of treatment. In addition to microbial contamination, water normally contains suspended solids, dissolved inorganic ions and organic compounds (mainly humic substances) which may affect the efficacy of solar photocatalysis. In this wo...

Population growth and climate change has a huge impact on water availability. To ensure secure supply, water-reuse concepts its implementation are gaining more importance. Additionally, saving potentials to optimize the drinking reuse availability have be considered. However, limited spatial planning opportunities missing regulation provide treated wastewater according “fit-for-purpose” princip...
