Coagulation Optimization With Real Time Organics Monitoring
Awareness about the negative effects of natural organic matter (NOM) within water and wastewater processes has increased due to ubiquitous concentrations in surface waters and some ground water sources. The need for effective organics removal has become more important as utilities work to meet increasingly strict regulations and optimize treatment technologies.
Though NOM consists of many carbon-based compounds, the most problematic type for water and wastewater treatment is the aromatic compounds. The ring structure of carbon atoms cause these compounds to readily attach with various functional groups. In general, aromatic organics such as humic acids tend to be more reactive than the other constitutes of NOM.
