Heavy 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 کاملBiodegradation of Lignocelluloses in Sewage Sludge Composting and Vermicomposting
Aims of the Study: The aim of this study was to determine the amount of lignin degradation and biodegradation of organic matter and change of biomass under compost and vermicomposting of sewage sludge. Materials & Methods: Sawdust was added to sewage sludge at 1:3 weight bases to Carbon to Nitrogen ratio of 25:1 for composting or vermicomposting. Lignin and volatile solids were deter...
متن کاملBiofuel Production from Biomasses, Municipal Solid Waste and Sewage Sludge
The aim of this research line is to study and optimize the production of biofuels through the anaerobic digestion (AD) of organic waste (biohydrogen and biomethane) and the exploitation of lipid-rich biomasses and waste matrices (biodiesel). The research on anaerobic digestion has the following goals: a) the study of the biomethanization of unconventional waste matrices, such as algae, municipa...
متن کاملEffect of temperature on composting of sewage sludge.
The effect of temperature on the composting reaction of sewage sludge was investigated at 50, 60, and 70 degrees C. The total amount of CO(2) evolved and the final conversion of volatile matter were maximum at 60 degrees C., suggesting that the optimal temperature for composting was around 60 degrees C. The specific CO(2) evolution rate (moles of CO(2) evolved per hour per viable cell) was maxi...
متن کاملVariations of metal distribution in sewage sludge composting.
In the study, the variations of heavy metal distributions (of Cu, Mn, Pb, and Zn) during the sewage sludge composting process were investigated by sequential extraction procedures. The total content of Cu and Zn in the composted mixture increased after the composting process. Mn and Zn were mainly found in mobile fractions (exchangeable fraction (F1), carbonate fraction (F2), and Fe/Mn oxide fr...
