This work presents the application of Fenton's reagent process combined with anaerobic digestion to treat an olive mill wastewater (OMW). Firstly, OMW was pre-treated by chemical oxidation in a batch reactor reagent, using fixed H2O2/COD ratio 0.20, pH = 3.5 and H2O2/Fe2+ molar 15:1. advanced treatment allowed reaching reductions 17.6 82.5% oxygen demand (COD) total polyphenols (TP), respectively. Secondly, performed previously adapted microorganisms immobilized Sepiolite. These biological...
A factorial central composite orthogonal and rotatable design was employed to optimize the carbamazepine degradation using an integrated Fenton + Fenton-like oxidation process. The pH initial concentrations of hydrogen peroxide ferrous ferric ions were considered as variables for process optimization. experiments procedure has been carried out in order well study interactions existing between four under study. concentration found be most important variable conditioning removal efficiency,...
Tartrazine degradation was investigated by electrochemical and sonochemical oxidation processes. Anodic carried out using boron-doped diamond (BDD) electrodes. The influence of current density dye initial concentration on the removal tartrazine from water analyzed. experimental results indicate that total obtained, Chemical Oxygen Demand (COD) Total Organic Carbon (TOC) removals up to 94.4% 72.8% were achieved, respectively. To optimize process, pollutant percentage, kinetic rate constant,...
Degradation of olive mill wastewater (OMW) by means two chemical oxidation processes (Fenton's reagent and ozonation) their consecutive treatments with aerobic microorganisms have been studied. Fenton's treatment moderately reduces COD to a greater extent the polyphenolic compounds. Ozonation contributed low conversion moderate reduction polyphenols. The biological degrade values higher than 70% 90% for compounds, respectively. A kinetic study has carried out in each process, determining...
This is a two-part work on the chemistry of iron(III) as coagulant in treatment cork processing wastewater. The main aim first part was to determine removal organic matter measured by reductions chemical oxygen demand (COD), polyphenols (P), and aromatic compounds (A) that can be obtained using this physicochemical process. To end, jar-test experiments were used optimal conditions for process, particular, effective iron dosage, temperature, contamination level wastewater, mixing time,...
A wide variety of drugs have been found in wastewater treatment effluents, rivers, and lakes, including analgesics, antibiotics, antiepileptics. Electrochemical advanced oxidation processes are promising technologies to treat low contents toxic biorefractory pollutants water. Anodic carbamazepine, the most frequently detected drug water bodies, was carried out using boron-doped diamond (BDD) anodes at galvanostatic mode. To optimize process study interaction between four modified variables...
Ozonation is a promising technology for the treatment of biorefractory compounds. Parabens belong to chemical family apparently innocuous preservatives that have been used in food and cosmetic industries several years. Oxidation different parabens, such as methylparaben (MP), ethylparaben (EP), propylparaben (PP), butylparaben (BP), was carried out using O3 ultrapure water. A design experiments procedure has order optimize ozonation process well study interaction between studied variables:...
In the present work, an integrated Fenton-coagulation/flocculation process was applied for depuration of wine distillery wastewaters, commonly known as "vinasses". This study evaluates Fenton (H2O2/Fe2+), involving oxidation--in a first stage and coagulation/flocculation (using Ca(OH)2 base-precipitant)--in second removal chemical oxygen demand (COD). The experimental variables studied were dosages hydrogen peroxide iron salts, molar ratio [H2O2]o: [Fe2+]o, effluent dilution manner in which...
