The wet oxidation process at °C decreased the concentration of ethylene glycol from to mol l −1, while at lower temperatures its concentration decreased to – mol l −1. Kinetic modelling. Various models have been proposed for describing the wet oxidation of simple compounds and by: Wet air oxidation (WAO) is a commercial technology used for treating a variety of industrial wastewaters such as chemical production effluents, textile effluents, effluents from paper mills, olive. Catalytic wet oxidation of real process wastewaters Arezoo nia, Antal Tunglera* Zsolt E. Horváthb, Zoltán Schaya, Éva Szélesa aInstitute of Isotopes HAS bResearch Institute for Technical Physics and Material Science Konkoly Thege M. út H Budapest, Hungary (E-mail: [email protected]; E-mail: [email protected]). Wet Air Oxidation Technology description. In WAO, oxidizable materials, usually organic materials, are oxidized in a dilute, aqueous, liquid matrix at temperatures of to °C ( to °F); the corresponding pressures required to maintain a liquid phase .

Wet oxidation of concentrated wastewaters: process combination and reaction kinetic modelling. Lap-peenranta (Finland) Acta Universitatis Lappeenrataensis Jan Wet air oxidation (WAO) is a well established technology for wastewater treatment, particularly for the treatment of toxic and highly concentrated wastewaters []. It is a chemical oxidation process involving organics or oxidizable inorganic components.   Wet Air Oxidation Wet oxidation is a hydrothermal treatment of aqueous solutions of biologically recalcitrant and hazardous chemicals/wastes. It is the oxidation of dissolved or suspended matter in water using an oxidant such as ozone, oxygen, hydrogen peroxide, air etc. Abstract. A novel advanced oxidation process—wet electrocatalytic oxidation (WEO) was studied with p-nitrophenol as model pollutant and β-PbO 2 electrode as the anode. Compared with the effect of the individual wet air oxidation (WAO) and electrochemical oxidation (EO), the effect of WEO showed synergistic effect on COD removal under the conditions of temperature °C, C= mgL −1 Cited by: 7.

Catalytic Wet Air Oxidation. The CWAO process is capable of converting all organic contaminants ultimately to carbon dioxide and water, and can also remove oxidizable inorganic components such as cyanides and ammonia. The process uses air as the oxidant, which is mixed with the effluent and passed over a catalyst at elevated temperatures and pressures.   Treatment of refractory organic pollutants in industrial wastewater by wet air oxidation 2 3.
