Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Over the past three decades, the occurrence of high concentrations of arsenic (As) in drinking water has been recognized as a severe global public-health concern (Bhattacharya et al. 2002, Mandal and Suzuki 2002, Ng et al. 2003). The global As-contamination scenario has changed considerably in recent years, with the discovery of new As affected sites. The delayed health effects of exposure to As, the lack of common definitions and of local awareness, as well as poor reporting in affected areas are all major problems in determining the extent of the arsenic-in-drinking-water problem (WHO 2008).

Membrane technologies for water treatment : Removal of toxic trace elements with emphasis on arsenic, fluoride and uranium
- 2016
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Focuses on the application of membrane technologies in removing toxic metals\metalloids from water. Particular attention is devoted to the removal of arsenic, uranium, and fluoride. These compounds are all existing in the earth's crust at levels between two and five thousands micrograms per kg (parts per million) on average and these compounds can be considered highly toxic to humans, who are exposed to them primarily from air, food and water. In order to comply with the new maximum contaminant level, numerous studies have been undertaken to improve established treatments or to develop novel treatment technologies for removing toxic metals from contaminated surface and groundwater. Among the technologies available, applicable for water treatment, membrane technology has been identified as a promising technology to remove such toxic metals from water. The book describes both pressure driven (traditional processes, such as Nanofiltration, Reverse Osmosis, Ultrafiltration,etc) and more advanced membrane processes (such as forward osmosis, membrane distillation, and membrane bio-reactors) employed in the application of interest. Key aspect of this book is to provide information on both the basics of membrane technologies and on the results depending on the type of technology employed.
