Removal of natural organic matter from aqueous solutions by electrocoagulation
Natural organic matter (NOM) affects some qualitative parameters of water such as color. In addition, it can deteriorate the performance of water treatment process including coagulation, adsorption, and membranes. NOM also reacts with chlorine in the chlorination process and may form disinfection by-products. The present study was carried out in laboratory-scale in a batch system using a cylind...
متن کاملComparison of advanced oxidation processes for the removal of natural organic matter.
This study examined the impact of UV, ozone (O(3)), advanced oxidation processes (AOPs) including O(3)/UV, H(2)O(2)/UV H(2)O(2)/O(3) in the change of molecular weight distribution (MWD) and disinfection by-product formation potential (DBPFP). Bench-scale experiments were conducted with surface river water and changes in the UV absorbance at 254 nm (UV(254)), total organic carbon (TOC), trihalom...
متن کاملApplication of response surface methodology for optimization of natural organic matter degradation by UV/H2O2 advanced oxidation process
BACKGROUND In this research, the removal of natural organic matter from aqueous solutions using advanced oxidation processes (UV/H2O2) was evaluated. Therefore, the response surface methodology and Box-Behnken design matrix were employed to design the experiments and to determine the optimal conditions. The effects of various parameters such as initial concentration of H2O2 (100-180 mg/L), pH (...
متن کاملDegradation of Atrazine by Advanced Oxidation Processes
Advanced oxidation processes like ozonation (O3) and ultrasonic irradiation (US) can be employed for the removal of recalcitrant compounds from water matrices. Atrazine is a pesticide which has been banned in the EU countries, since it is toxic and potentially carcinogenic even in very small concentrations. After their use in agricultural areas, the pesticides tend to leave residuals on the soi...
متن کاملModeling of natural organic matter transport processes in groundwater.
A forced-gradient tracer test was conducted at the Georgetown site to study the transport of natural organic matter (NOM) in groundwater. In particular, the goal of this experiment was to investigate the interactions between NOM and the aquifer matrix. A detailed three-dimensional characterization of the hydrologic conductivity heterogeneity of the site was obtained using slug tests. The transp...
