Size-exclusion chromatography in combination with organic carbon detection (SEC-OCD) is an established method to separate the pool of NOM into major fractions of different sizes and chemical functions and to quantify these on the basis of organic carbon. One specific approach, also known as LC-OCD-OND, is based on the Gräntzel thin-film UV-reactor. This approach is described with recent improvements...
Fouling of membranes by organic substances precludes that these organics are present in the feed water, most likely in a dissolved state. Analysis of feed waters for such constituents can help to find the causes, and later the solutions, for membrane fouling. Two examples are presented in which this strategy was successful, in the first example polysaccharides and hydrophobic organic compounds were...
