abstract background: dyes are visible materials and are considered as one of the hazardous components that make up the industrial waste. dye compounds in natural water, even in very low concentrations, will lead to environmental problems. azo dyes are compounds with one or more –n=n– groups and are used in textile industry. because of its low price, solubility, and stability, azo dyes are widel...
Abstract Combining electrocoagulation with another process is a potential strategy for increasing the efficiency of water and wastewater pollutant removal. The integration advanced oxidation processes (AOPs) (EC) demonstrates improved performance. mechanism EC combined ozone (O 3 ), hydrogen peroxide (H 2 O sulfate radicals, electrooxidation (EO), Fenton/electro-Fenton, UV discussed. This revie...
In order to improve the degradation efficiency of pulping and papermaking wastewater, the combination oxidation process of Fenton with ultrasonic irradiation was carried out. The processes of ultrasonic irradiation alone and Fenton oxidation alone on pulping and papermaking wastewater treatment were optimized respectively. Basing on the optimum process of Fenton oxidation, the synergistic effec...
A novel electro-Fenton (E-Fenton) process was developed, in which the desired pH for an effective E-Fenton reaction and for a neutral treated media could be obtained by utilizing the reaction-released H+ and OH- in stead of chemical addition. In the laboratory-scale process using three chambers, the substrate solution pH > 4.0 was designed to be adjusted in situ through three sequencing steps: ...
the saline tannery wastewater also contains the high concentration of organic materials and various chemical compounds like lime, sodium sulfite, sulfate ammonium, sodium chloride, disinfections, vegetable tannins, salts of chromium and chloride. in recent years different applications of advanced oxidation processes (aops) are applied to remove organic loading (cod) from wastewater. advanced ox...
