Alternative conditioning of aluminium-based drinking water treatment sludge using Fenton reagent (Fe2+/H2O2) was examined in this study. Focuses were placed on effectiveness and factors to affect such novel application of Fenton process. Experiments have demonstrated that considerable improvement of alum sludge dewaterability evaluated by capillary suction time (CST) can be obtained at the rela...

Bi25FeO40 microtetrahedra, microcubes and microspheres were successfully synthesized by a simple hydrothermal process and by adding different additive agents. The formation mechanism of Bi25FeO40 microcrystals was proposed; the additive agents had important influences on the morphology and facet exposure of the products. The catalytic activity of these materials was evaluated by the degradation...

The influence of low-molecular-weight organic acids (LMWOAs), such as malonic acid, ethylenediaminetetraacetic acid, and oxalic acid, on the Fenton degradation of organic pollutants was examined under visible irradiation (lambda > 450 nm). The Fenton degradation of malachite green in the dark was completely blocked in the presence of LMWOAs. It was found that either visible light irradiation or...

Background: This research studied the effect of UV light on pentachlorophenol (PCP) removal in the electro-Fenton (EF) process. Methods: PCP was used as the pollutant in this study. The effects of Fenton’s reagent, i.e. hydrogen peroxide concentration, solution pH, and treatment time by EF (EF) and photoelectro-Fenton (PEF) processes, were studied to determine rates of PCP removal. The r...

The present study was conducted in order to investigate the efficiency of different advanced oxidation processes both individually and combination with biological method for removal color chemical oxygen demand (COD) from wastewater pulp paper industry. Advanced include ozone, Fenton, hydrogen peroxide, photo-Fenton. Biologically treated successively subjected (AOPs). optimum conditions ozone t...

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...

We come to the recovery concept from 2 different directions. F.F. is a consumer professional who has both a scientific appreciation for schizophrenia as an illness and personal experience of battling both the illness and stigma from mental health professionals and the community. He came to the recovery concept as a function of his personal struggles and growth. A.S.B. is a behavior therapist wh...
