Focuses at the program of membrane applied sciences in removal poisonous metals\metalloids from water. specific awareness is devoted to the removing of arsenic, uranium, and fluoride. those compounds are all present within the earth’s crust at degrees among and 5 hundreds of thousands micrograms according to kg (parts in line with million) on typical and those compounds may be thought of hugely poisonous to people, who're uncovered to them basically from air, foodstuff and water. so one can agree to the hot greatest contaminant point, quite a few reports were undertaken to enhance validated remedies or to strengthen novel therapy applied sciences for removal poisonous metals from infected floor and groundwater. one of the applied sciences to be had, acceptable for water therapy, membrane expertise has been pointed out as a promising expertise to take away such poisonous metals from water. The book describes either strain pushed (traditional methods, akin to Nanofiltration, opposite Osmosis, Ultrafiltration,etc) and extra complicated membrane approaches (such as ahead osmosis, membrane distillation, and membrane bio-reactors) hired within the program of curiosity. Key element of this publication is to supply details on either the fundamentals of membrane applied sciences and at the effects counting on the kind of expertise hired.

Chapter 4 focuses on the reverse osmosis (RO) process and the removal of As, F− and U by reverse osmosis (RO) using different types of membrane modules. Chapter 5 presents the most relevant electromembrane processes for treating water containing traces of toxic contaminants and addressing the removal of As, F– and U. Two case-studies are reported and discussed in order to illustrate the possible successful application of Donnan dialysis, applied either as a single treatment or part of an integrated approach for the removal of arsenate and ionic mercury from contaminated water sources.

Arsenic, typically appearing in water as anionic species, became first a local concern in the nineteen nineties when naturally occurring arsenic in groundwater, used for domestic needs, revealed severe health impacts in Bangladesh and parts of Eastern India. Gradually it became a worldwide concern. In the United States, the Environmental Protection Agency ran a demonstration program in which many technologies from all parts of the world were tested for their efficacy in removing arsenic from ground water.
