water organics monitoring Articles
-
Surface waters have varying levels of organics that originate from both natural and anthropogenic sources.
These organic compounds can cause challenges for the water treatment plant by increasing coagulant demand, causing taste and odor issues and increasing demand for disinfectants. Even when the organics themselves are not a health hazard, when combined with chlorine they may lead to the formation of harmful disinfection byproducts (DBPs). Reducing the concentration of organics via various treatment ...

Hydrogeochemical and biological processes affecting the long-term performance of an iron-based permeable reactive barrier
Received for publication November 29, 2007. Despite the wide diffusion of zero-valent iron (Fe0) permeable reactive barriers (PRBs), there is still a great uncertainty about their longevity and long-term performance. The aim of this study is to investigate the biological and the hydrogeochemical processes that take place at a Fe0 installation located in Avigliana, Italy, and to derive some ...
