Removal of Heavy Metals from Urban Sewage Sludge Using Acidophilic Thiobacillus ferrooxidans
Background & objectives: The presence of heavy metals in urban sewage sludge limits its use as a soil modifier. The purpose of this study was to remove heavy metals (Cu, Zn, Cd and Pb) from urban sewage sludge using Acidophilic Thiobacillus ferrooxidans bacteria. Methods: In this experimental study, the sludge samples were collected from Shiraz wastewater treatment plant. Bioleaching tests were...
متن کاملMobility of heavy metals in soils amended with sewage sludge
Morera, M. T., Echeverría, J. C. and Garrido, J. J. 2001. Mobility of heavy metals in soils amended with sewage sludge. Can. J. Soil Sci. 81: 405–414. Sewage sludges added to arable land can improve soil fertility and physical properties. However, the concentrations of heavy metals commonly found in sludges limits their application to soil. The purpose of this paper is to evaluate the mobility ...
متن کاملBioavailability of heavy metals in soils amended with sewage sludge
Morera, M. T., Echeverría J. and Garrido, J. 2002. Bioavailability of heavy metals in soils amended with sewage sludge. Can. J. Soil Sci. 82: 433–438. The recycling of sewage sludge to agricultural land results in the slow accumulation of potentially toxic heavy metals in soils. A greenhouse experiment was conducted to determine the bioavailability of Cu, Ni, Pb and Zn applied to soils in urban...
متن کاملHeavy Metals Removal from Sewage Sludge and Municipal Solid Waste (MSW) by Co-Composting Process
Background & Aims of the Study: One of the most important pollutants in drinking water, air and soils is heavy metals. It is very harmful for humans and other live organisms. The purpose of this study was the usage of a co-composting process for removal of heavy metals from municipal solid waste and sewage sludge. Materials and Methods: This experimental study was a condu...
متن کاملCorrelation between biological agents and levels of heavy metals in municipal sewage sludge.
During the period 2003-2004, 110 samples of sewage sludge were examined from 18 treatment plants located in the territory of the whole of Poland, the majority in the Lublin Province. Samples of fermented and dehydrated sewage sludge were taken from sludge drying beds. The bacteriological and parasitological determinations covered bacteria of the Salmonella genus and eggs of the helminths Ascari...
