| Zusammenfassung: | Arsenic abatement from groundwater in locations with a central water distribution system is relatively simple. The real challenge is selecting the most effective and affordable treatment and scale up option for locations which lack the appropriate infrastructure. Groundwater Arsenic Remediation: Treatment Technology and Scale UP provides the latest breakthrough groundwater treatment technologies and modeling and simulation methods for project scale up and eventually field deployment in locations which lack the proper central water distribution system to ensure arsenic free groundwater |

Groundwater Arsenic Remediation: Treatment Technology and Scale UP provides the latest breakthrough groundwater treatment technologies and modeling and simulation methods for project scale up and eventually field deployment in locations which lack the proper central water distribution system to ensure arsenic free groundwater TECHNOLOGY & ENGINEERING / Environmental / Water Supply bisacsh Groundwater / Arsenic content Groundwater / Purification / Arsenic removal Grundwassersanierung (DE-588)4510696-4 gnd rswk-swf Arsenbelastung (DE-588)4143081-5 gnd rswk-swf Electronic books Grundwassersanierung (DE-588)4510696-4 s Arsenbelastung (DE-588)4143081-5 s DE-604 Erscheint auch als Druck-Ausgabe 978-0-12-801281-9 http://www.sciencedirect.com/science/book/9780128012819 Verlag URL des Erstveröffentlichers Volltext |
