pentachlorophenol (pcp) is a very hazardous compound which enters into the environment byindustries such as refineries and petrochemicals. as its biological degradation is very slow, this usemay cause the pollution of soils and groundwater; with the recent emergence of pentachlorophenolcontamination as an important drinking water quality issue, finding an easy, economical, and usefulmethod to r...
Biological treatment, due to the formation of hazardous chemicals remove organic compounds such as dimethyl sulfoxide (DMSO) and N, N-dimethylacetamide (DMAC), has limited potential. Advanced oxidation processes (AOPs) are regarded a viable alternative for treating molecules containing carbon-hydrogen bonds that cannot be broken down by traditional physico-chemical methods. In this investigatio...
a general overview on the prospective of various oxidation and combined processes in the treatment of tannery industry effluent are reported. various oxidation and combined processes such as uv/h2o2/hypochlorites, fenton and electro-oxidation, photo-chemical, photo-catalytic, electro-catalytic oxidation, wet air oxidation, ozonation, biological followed by ozone/uv/ h2o2, coagulation or ele...
In this study, Chemical Oxygen Demand (COD) from a pharmaceutical wastewater (PhW) was reduced by several techniques such as electro-Fenton (EF), photo electro-Fenton (PEF) and activated sludge (AS) processes and the obtained data were compared with each other. The effects of several parameters such as pH, current density, H2O2/Fe2+ molar ratio, volume ratio of ...
MicrosoftInternetExplorer4 Background and Objectives: Synthetic dyes represent one of the largest groups of pollutants in wastewater of dying industries. Discharging these wastewaters into receiving streams not only affects the aesthetic but also reduces photosynthetic activity. Electrochemical advanced oxidation processes such as Electro-Fenton process are low operational and have high mi...
The performance of a new electro-Fenton process with Ti-based mixed metal oxides (Ti/MMO) cathode, a dimensionally stable electrode, is evaluated for degrading contaminants of emerging concerns (CECs) in aqueous solutions. Bisphenol A (422μgL(-1)) is completely degraded in an undivided cell using Ti/MMO as the cathode in the presence of 6.9mgL(-1) Fe(2+) within 20min under conditions of pH 4 an...
The three-dimensional electro-Fenton method was used in the folic acid wastewater pretreatment process. In this study, we researched the degradation of folic acid and the effects of different parameters such as the air sparging rate, current density, pH and reaction time on chemical oxygen demand (COD) removal in folic acid wastewater. A four-level and four-factor orthogonal test was designed a...
Oxidation of 2,6-dimethylaniline by electro-Fenton process in acidic solution at pH 2 was investigated. The effects of pH, Fe(2+), H(2)O(2) and current density were assessed to determine the optimum operating parameters. The oxidation efficiency of 2,6-dimethylaniline was determined by the reduction of 2,6-dimethylaniline, COD and TOC in the solutions. Results reveal that 1 mM of 2,6-dimethylan...
background: car wash waste water contains several contaminants such as organic matter, oil, grease, detergents and phosphates, all of which are harmful for the environment. in this study, the application of electrocoagulation (ec) to treat car wash waste water has been studied, and the operating parameters optimized. the electro-fenton (ef) for further contaminant removal was also investigated....
