Hybrid water vapor sorbent design with pollution shielding property: extract clean water from polluted bulk water sources

Providing clean water, keeping water clean: an integrated approach.

Millions of people, most of whom are children in developing countries, die of basic hygiene-related diseases every year. Interventions in hygiene, sanitation and water supply have been shown to control disease burden. Universal access to improved water sources and basic sanitation remains elusive but is an important long-term goal. Studies have shown that improving the microbiological quality o...

Clean Water Act

Definition The US Congress enacted the Clean Water Act in 1972 (P.L. 92-500, the 1972 Amendments to the Federal Water Pollution Control Act), which is the principal law dealing with polluting activity in streams, rivers, lakes, and estuaries of the USA (Copeland, 2006). The Clean Water Act established a water quality standards approach for regulating water quality, with the US Environmental Pro...

Water quality risks of 'improved' water sources: evidence from Cambodia.

OBJECTIVES The objective of this study was to investigate the quality of on-plot piped water and rainwater at the point of consumption in an area with rapidly expanding coverage of 'improved' water sources. METHODS Cross-sectional study of 914 peri-urban households in Kandal Province, Cambodia, between July-August 2011. We collected data from all households on water management, drinking water...

Decontamination of Water Polluted with Phenol using Raphanus sativus Root

Plant materials have been found useful in decontamination of water polluted with phenolic compounds. The detoxification effect is due to peroxidases contained in plant tissue. Enzyme mediated oxidative coupling of phenol is followed by precipitation of the formed polymer and its removal from the aqueous phase. A synthetic wastewater buffered at pH = 7.4 containing 0.9 mM phenol was treated in t...
