Grey water is a kind of domestic wastewater including shower, bath, lavatory and laundry waters. waters without faecal waste can be considered as alternative sources in the place where resources are limited. In present study, removals COD, anionic non-ionic surfactants from grey via conventional (CFP) modified (MFP) Fenton oxidation processes was experienced. It determined that pH adjustment to...

This study relates to a method for evaluating the degradation efficiency of Ascaris lumbricoides eggs through a Fenton reaction, using hydrogen peroxide (H2O2) at 100, 250, and 500 mg/L, ferrous sulfate (FeSO4) at 458 mg/L Fe(2+) and pH values of 3, 4.5, and 6. The experiments were conducted according to a 3(2) experimental design, with 1:1, 3:1, and 5:1 (H2O2/Fe(2+)) molar ratios. The oxidatio...

A novel Pd-based electro-Fenton (E-Fenton) process has recently been developed to transform organic contaminants in groundwater. However, it only produces H2O2 and requires addition of Fe(2+). In this study, an innovative approach is developed to effectively regulate the generation of Fe(2+) from an iron cathode in a three-electrode system in addition to H2O2 production. The Fe(2+) is then used...

This paper presents results of studies on an effect of humate (HS) on chemical (Fenton) and biological treatment of wastewater with high content of organic compounds and heavy metals. All studies focused on practical applications of HS, allowing reducing the concentration of the contaminants of concern before their discharge to the natural water bodies (or to the ground). Laboratory tests showe...

ABSTRACT Although traditional Fenton reaction is known for a long time, it is still a perspective method for removal of pollution from wastewater. Applications of electro-Fenton oxidation are commonly used in wastewater treatment. These methods are classified into groups-electrochemical advanced oxidation processes. Typical catalysts for these technologies are Fe2+ ions. Comparison between two ...

A novel iron-containing mesostructured material has been successfully tested for the heterogeneous photo-Fenton degradation of phenolic aqueous solutions using near UV-visible irradiation (higher than 313 nm) at room temperature and close to neutral pH. This catalyst is a composite material that contains crystalline hematite particles embedded into the mesostructured SBA-15 matrix in a wide dis...

The practical application of the Fenton-based treatment method for organic compounds-contaminated water purification is limited mainly because of the large amount of ferric sludge formed during the treatment, where ferrous iron (Fe(II)) is used as the activator of the hydrogen peroxide oxidation processes. Reuse of ferric sludge collected from clarifiers to substitute Fe(II) salts allows reduci...
