Effect of Ozone on Removal of Dissolved Organic Matter and its Biodegradability and Adsorbability in Biotreated Textile Effluents
TLDR
In this article, a study was conducted on the efficacy of ozonation in removing dissolved organic matter (DOM) in biotreated textile effluents and effects on its biodegradability and adsorbability.Abstract:
A study was conducted on the efficacy of ozonation in removing dissolved organic matter (DOM) in biotreated textile effluents and effects on its biodegradability and adsorbability Results showed the efficient removal of color and fluorescence compounds were achieved through ozonation, due to increasing hydrophilicity and lowering molecular weight of DOM A significant biodegradability improvement was also observed, and DOM adsorbability on activated carbon was highly dependent on ozone dosage As the key parameter, consumed 38 g O3/ g TOC0 was the optimal dosage in the hybrid process combining ozonation with biological activated carbon (BAC) for wastewater reclamationread more

Novel insights into variation of dissolved organic matter during textile wastewater treatment by fluorescence excitation emission matrix
TL;DR: In this paper, the textile wastewater samples along two full-scale treatment trains were characterized by fluorescence excitation emission matrix (EEM) and four fluorescent components (C1-C4) were identified by parallel factor (PARAFAC) analysis.

Effect of Chemical Oxidation on the Sorption Tendency of Dissolved Organic Matter to a Model Hydrophobic Surface
TL;DR: Evaluated changes in the noncovalent interactions of proteins, polysaccharides, fatty acids, and humic and fulvic acids with a model hydrophobic surface suggest that ozone pretreatment would minimize membrane fouling by DOM, while chlorine pret treatment would promote DOM removal by activated carbon.

TL;DR: In this article, standards for reporting C-14 age determinations are discussed, and the statistical uncertainty (plus or minus one standard deviation) expresses counting errors, inaccuracies in voltage, pressure, temperature, dilution, and should include errors in C-13 ratios.

Fluorescence excitation-emission matrix regional integration to quantify spectra for dissolved organic matter.
TL;DR: Aromatic carbon and the presence of specific aromatic compounds resulted in EEMs that aided in differentiating wastewater effluent DOM from drinking water DOM, and the highest cumulative EEM volume was observed for hydrophobic neutral DOM fractions.
