*Corresponding author Email: [email protected] In this work, the treatment of organics present in printing ink wastewaters such as dyes (methylene blue and rhodamine B), surfactants (sodium dodecylbenzene sulfonate), and solvents (ethylene glycol), as well as actual printing ink wastewaters by advanced oxidation processes, namely conductive diamond electrochemical oxidation (CDEO), Fenton...

Leachate pollution is one of the main problems in landfilling. Among the most problematic parameters in stabilized leachate are COD, ammonia, and color. The treatment technology that can be used may differ based on the type of leachate produced. Even after treatment, the effluent characteristics are always hard to comply with the discharge standard. Ozonation is one of the chemical processes th...

Spectrophotometric examinations showed the presence of phenolic compounds in the organic residue collected from four groundwater resources located in vicinity of an oil refinery at the outskirt of Tehran. The average concentration of total phenolic compounds was about 0.38 mg.L-1 in these samples using Folin-Ciocalteu method. GC-Mass analysis disclosed that alkylphenols were the major phenolic ...

Diclofenac is a drug with an analgesic effect that accumulates and results in adverse consequences if it enters the human body more than needed. Low concentrations of diclofenac have been detected in different water sources through leachates of landfills and agricultural areas, human and animal excreta expired drug discharge and hospital effluents. To eliminate diclofenac from the aquatic e...

Several advanced oxidation processes such as hydrogen peroxide photolysis, the Fenton treatment, photo-Fenton treatment, and ozonation combined with hydrogen peroxide and UVradiation for the destruction of 2,4-dinitrophenol were studied. Advanced oxidation processes, especially the Fenton treatment, were found to be effective for the degradation of 2,4-dinitrophenol and removal of toxicity. Acc...

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...

The intricate nature of various textile manufacturing processes introduces colored dyes, surfactants, and toxic chemicals that have been harmful to ecosystems in recent years. Here, a combination ozone-based advanced oxidation process (AOP) is coupled with nanobubbles generator for the generation ozone (NB) utilized same treat primary effluent acquired from wastewaters. Here we find several key...
