Aerobic Sludge Digestion in the Presence of Chemical Oxidizing Agents Part II. Fenton's Reagent
نویسندگان
چکیده
Aerobic sludge digestion in the presence of Fenton's reagent and hydrogen peroxide was examined. Fenton's reagent considerably improved the aerobic digestion process in comparison with hydrogen peroxide as well as classical aerobic digestion. Application of Fenton's reagent also led to improvement of settling and dewatering properties of sludge and much better clarity of supernatant. Its drawback, however, is the formation of chemical precipitate and an apparent decrease in pH which might inhibit biochemical processes important for aerobic digestion efficiency.

The process of sludge digestion using hydrogen peroxide as the only oxidizing agent was carried out. It was pointed out that the application of H2O2 to the digestion process is possible provided that aerobic conditions of the process are strictly controlled in the course of the process. Since H2O2 should be added frequently into the digestion chamber it is highly recommended to supply the diges...
متن کاملExploitation of Fenton and Fenton-like reagents as alternative conditioners for alum sludge conditioning.
The use of Fenton's reagent (Fe2+/H2O2) and Fenton-like reagents containing transition metals of Cu(II), Zn(II), Co(II), and Mn(II) for an alum sludge conditioning to improve its dewaterability was investigated. The results obtained were compared with those obtained from conditioning the same alum sludge using cationic and anionic polymers. Experimental results show that Fenton's reagent was th...
متن کاملThermophilic Aerobic Digestion of Activated Sludge; Reduction of Solids and Pathogenic Microorganisms
In the temperature range of 10 to 80 ºC and in a batch digester, a typical activated sludge was digested aerobically. Reaction rate constants were determined by measuring the amounts of volatiles removed from the suspended solids at different time intervals during the process. The maximum value of the reaction rate constant (0.45 d-1) occurred in the temperature...

Reaction constants and heat release during thermophilic aerobic digestion of typical secondary and mixed sludges were determined. Maximum reaction constant, determined by measuring the amounts of biodegradable volatile suspended solids (bVSS) removed, occurred in the temperature range of 55-60 ºC. Measurement of heat releases were carried out, at the same range, by the aid of a temperature ...
