Recovering more energy from plant material is a constant challenge in biogas research. A recent study from Sandia National Laboratories shows how a chemical post-treatment applied after digestion can release additional biomethane from otherwise resistant material. Optimising the anaerobic digestion process Biogas and biomethane are produced through anaerobic digestion (AD). Along with these ...
They exhibit exceptional catalytic activity in Fenton-like processes, with a remarkable 88% decolorization ratio of indigo carmine in the presence of H2O2. ...
Here is a list of some of the most common consumables: Reagents: Reagents are used in lab tests to measure or detect the presence of other substances. Examples of reagents include Fenton’s reagent, which is used to neutralize certain toxic organic compounds, and Fehling's reagent, which is used to test for reducing and non-reducing sugars. ...
Commonly used techniques for ultrasonic oxidative desulfurization: Ultrasonic-H2O2-inorganic acid oxidation and desulfurization technology Ultrasonic-H2O2-Organic Acid Oxidation and Desulfurization Technology Ultrasonic-H2O2-Solid Acid Oxidation and Desulfurization Technology Ultrasonic-H2O2-Fenton reagent oxidative desulfurization technology ...

Another example of products based on a chemical reaction strategy are practical implementations of a well-understood chemical principle known as Fenton's Reagent Chemistry. FRC provides for direct oxidation -- release of nascent oxygen -- via an exothermic reaction between a peroxide and a catalyst. ...
Project Location: North Central California Volume of soil: 250 yd3 Contamination type(s): Diesel fuel Average level of contamination: 370 PPM Results from confirmation testing: Non-detect for diesel and BTEX for all samples (sensitivity: parts per-million) Location: North Central California Treatment: Oxidizer w/fentons reagent Volume of soil: 250 yd3 Contamination type(s): ...
Former admixed drilling sump at an abandoned wellsite. Surficial soil impacts were excavated and removed from Site. Shallow groundwater limited excavation and required in-situ treatment method for remaining soil impacts and groundwater impacts. Lithology of the target treatment zone is saturated silty sand, creating a pathway for contaminant ...

These include ultraviolet photolysis, hydrogen peroxide oxidation, photo-Fenton’s oxidation, electrochemical oxidation, and ozonation. APOs may sometimes be used for removal of toxic compounds like PAHs. ...
The ground water contamination had migrated from leaking sewer lines to underlying bedrock fractures. Fenton’s Reagent was first applied to the site, but the PCE concentrations increased due to desorption. ...
This paper explores the formation of OH radicals and the removal of trace substances by means of ozone, UV/H2O2 and the Fento and photo-Fenton reaction in more detail and outlines some examples of application in ...
Fenton is a classic rural American city nestled approximately 65 miles north of Detroit in the state of Michigan. Although not one of the bigger metropolises’ in the US, Fenton takes pride in its use of new technologies to better serve its residents. ...
Furthermore, there was a significant increase of 13.4% in the COD removal efficiency with the introduction of oxalate compared with UV/Fenton. Experimental results show that the coagulation and UV/H2O2/ferrioxalate complexes process could efficiently remove the organic material dissolved in OFW. ...
Furthermore, COD removal efficiency significantly increased by more than 13.4% with the introduction of oxalate compared with UV/Fenton. The UV_vis spectra analysis results indicated that the coagulation and UV/H2O2/ferrioxalate complexes process could efficiently remove the hydroxypropyl guar gum dissolved in OFW. ...
The dewaterability of excess sludge significantly improved upon pretreatment with Fenton's reagent in this study. After 0.9 g/L of Fe2+ and 5.0 g/L of H2O2 were added to the sludge, and reacted for 2 h at pH = 4, the specific resistance to filtration (SRF) of the excess sludge decreased from an initial value of 29.74 × 1012 m/kg to 6.49 × 1012 m/kg. ...
In this study, a combined process was developed that included micro-electrolysis, Fenton oxidation and coagulation to treat oilfield fracturing wastewater. Micro-electrolysis and Fenton oxidation were applied to reduce chemical oxygen demand (COD) organic load and to enhance organic components gradability, respectively. ...
This study proposes a new method showing that the addition of UV strongly enhanced the oxidation capacity of the Cu(II)/O2 process, which subsequently produced reactive oxidants using copper as a catalyst via the Fenton-like reactions of in situ generated hydrogen peroxide (H2O2). Acid orange 7 (AO7) was degraded more than 70% after 70 min at an initial pH of 3.5 in the ...
In this study, the adsorption and Fenton behavior of iron rich Terra Rosa soil was investigated for the treatment of aqueous anthraquinone dye (Reactive Blue 19 (RB19)) solutions. ...
In this contribution, removal efficiency of chemical oxygen demand (COD), acute toxicity, genotoxicity and estrogenicity in landfill leachate membrane concentrates (MCs) among UV-Fenton, Fenton and activated carbon adsorption process were compared. ...
The main objective of this study is to investigate the effect of ultrasound on the heterogeneous Fenton-like oxidation of acetic acid, which is one of the most resistant carboxylic acids to oxidation. ...
