Dissolved organic matter, water bodies, Granular Activated Carbon, membrane materials
Abstract
Dissolved organic matter (DOM) accounts for a great proportion of organic carbon in all aquatic ecosystems and is often a vital carbon resource for heterotrophic microorganisms. According to the Wet-chemical analysis and 1 H- and 13C-NMR spectra, it is clearly showed that both DOM fractions from the urban waste compost were low in neutral, acidic and amino sugars as well as in lignin derived compounds. In this article, directly or indirectly impacts of the human activities on water bodies are mentioned and the eutrophication, a common and harmful phenomenon of pollution, is introduced as one of the well-known results of concentrated DOM. As a result, human found several methods to remove the DOM. The most likely treatment to be implemented at present is Granular Activated Carbon Filtration (GAC), but it has been narrowly defeated due to its inability to meet the demand for large-scale deployment. Other solution like membrane materials and water-soluble materials are also competitive for organic water pollution removement.
