The generation of disinfection by-products during water treatment can be controlled by reducing the levels of precursor species prior to the chlorination step. The Natural Organic Matter (NOM) is the principal organic precursor and conventional removal of pollutants such as coagulation, flocculation and filtration do not guarantee the total NOM removal. In this study the degradation of NOM mode...

the performance of a plug flow electrocoagulation reactor for the treatment of cattle abattoir(slaughterhouse) wastewater was investigated. a cylindrical iron reactor was operated as a cathode at arecycling batch mode while three iron rods located at the center of the reactor were used as an anode. theeffects of different parameters, including the current density, the supporting electrolyte dos...

leachate treatment from municipal landfills has been always a major anxiety in waste management due to its high level of various contaminations. in this paper the effect of nanosized zero valent iron particles (nzvi) in fenton process for the treatment of high cod strength landfill leachate was scrutinized. the results corroborated this procedure was fast and efficient. in fact, about 87% of in...

Degradation of 2,4-dichlorophenol (2,4-DCP) was studied in a novel three-electrode photoelectrocatalytic (PEC) integrative oxidation process, and the factors influencing the degradation rate, such as applied current, flow speed of O2, pH, adscititious voltage and initial 2,4-DCP concentration were investigated and optimized. H2O2 was produced nearby cathode and Fe2+ continuously generated from ...

Sickle erythrocyte (RBC) membranes were previously shown to manifest increased Fenton activity (iron-dependent, peroxide-driven formation of hydroxyl radical [.OH]) compared with normal RBC membranes, but the nature of the catalytic iron was not defined. We now find that sickle membranes exposed to superoxide (.O2-) and hydrogen peroxide (H2O2) have three distinct iron compartments able to act ...

The removal efficiency of 4-chlorophenol with different advanced oxidation processes have been studied. Oxidation experiments were carried out using two 4-chlorophenol concentrations: 100 mg L and 250 mg L and UV generated from a KrCl excilamp with (molar ratio H2O2: 4-chlorophenol = 25:1) and without H2O2, and, with Fenton process (molar ratio H2O2:4chlorophenol of 25:1 and Fe concentration of...
