Nutrients and Heavy Metals in Biochar Produced by Sewage Sludge Pyrolysis: Its Application in Soil Amendment
The production of sewage sludge has been sharply increasing by municipal sludge treatment plants in China. Sewage sludge is a difficult waste to manage not only due to the high quantities produced but also due to its high concentration of heavy metals and pathogens. The pyrolytic conversion of sewage sludge to biochar and then applied to the land is a sustainable management potion. Therefore, t...
متن کاملPreparation and Application of Biochar from Brewery`s Spent Grain and Sewage Sludge
Brewery`s spent grain (BSG) and sewage sludge (SS) were used as raw material at the temperature from 400°C to 700 °C and limited oxygen (O2<5%) conditions to prepare biochar (BC). One aim is to examine the BC characterization prepared under different temperatures and various proportions of SS. Another aim is to find the optimum preparation conditions of BC for treating wastewater. Results showe...
متن کاملAdsorption and desorption of lead in Iranian acid and alkaline soils amended with sewage sludge-derived biochar
The effective management of sewage sludge materials in an environmentally and economically acceptable way is through the pyrolytic conversion of the sludge to biochar and its use for agricultural purposes. The aims of this work were: (1) to assess the effect of biochar prepared from sewage sludge at two different temperatures (350 ºC and 650 ºC) on the adsorption/desorptio...
متن کاملSewage Sludge Biochar: Physicochemical Properties and Fractionation of Zinc and Lead Metals
One of the significant factors affecting biochar properties is the pyrolysis temperature. This study aimed to investigate the effect of pyrolysis temperature on the properties and fractionation of Zn and Pb in biochars produced by sewage sludge. Biochars were prepared at temperatures of 300 to 700 °C and the physicochemical properties, availability, and fractionation of Zn and Pb were investiga...
متن کاملEffects of Biochar-Derived Sewage Sludge on Heavy Metal Adsorption and Immobilization in Soils
The object of this study was to evaluate the effect of sewage sludge biochar on adsorption and mobility of Cr, Mn, Cu, and Zn. Biochar (BC400) was produced via pyrolysis of municipal sewage sludge at 400 °C. Maximum adsorption capacities (qm) for Zn, Cr, Mn, and Cu were 5.905, 5.724, 5.681, and 5.342 mg·g-1, respectively, in the mono-metal solution and 2.475, 8.204, 1.01, and 5.415 mg·g-1, resp...
