Creation of affordable materials for constant release of silver ions in water is one of the most promising ways to provide microbially safe drinking water for all. Combining the capacity of diverse nanocomposites to scavenge toxic species such as arsenic, lead, and other contaminants along with the above capability can result in affordable, all-inclusive drinking water purifiers that can functi...

Osmotically driven membrane processes (ODMP) have gained renewed interest in recent years and they might become a potential solution for the world's most challenging problems of water and energy scarcity. Though the concept of utilizing osmotic pressure difference between high and low salinity streams across semipermeable membranes has been explored for several decades, lack of optimal membrane...

Water monitoring requires expensive instrumentations and skilled technicians. In developing Countries as Africa, the severe economic restrictions and lack of technology make water safety monitoring approaches applied in developed Countries, still not sustainable. The need to develop new methods that are suitable, affordable, and sustainable in the African context is urgent. The simple, economic...

Nearly all known biological warfare agents are intended for aerosol application. Although less effective as potable water threats, many are potentially capable of inflicting heavy casualties when ingested. Significant loss of mission capability can be anticipated even when complete recovery is possible. Properly maintained field army water purification equipment can counter this threat, but per...

Abstract This article aims to investigate environmental education in preschools by taking Donna Haraway’s call of staying with the trouble together preschool children seriously, here-and-now, explorations dirty water and purification. posthumanist inspired research project draws theoretically methodologically on writings Haraway, Anna L. Tsing Isabelle Stengers. The empirical data consist three...

General procedures, materials, and instrumentations. All airor water-sensitive reactions were carried out under a dry nitrogen atmosphere using standard Schlenk techniques. Fe and Ru ICP standards were obtained from Ricca Chemicals Co. (Arlington, TX). Unless otherwise stated, all chemicals and solvents were purchased from Aldrich Chemicals Co. (Milwaukee, WI) and used without further purificat...

Pumice and the Moringa oleifera (MO) seed were investigated as alternative natural materials for drinking water treatment based on problems identified at the Stretta Vaudetto water treatment plant in Eritrea. Lab and pilot scale studies showed that pumice was a suitable alternative material for dual media filtration. Conversion of the sand filters at Stretta Vaudetto to pumice-sand media would ...

The use of ion-exchange membranes to concentrate sea water and to produce fresh water from brine has been investigated for about one quarter-century and has now achieved the practical stage. The entire domestic supply of table salt in Japan is produced by electrodialysis. Many positive results on production of fresh water from brine have been attained in the U.S., the Mediterranean regions and ...
