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 کاملSewage Sludge-derived Adsorbents for H2s Removal
Various methods have been used to dispose of or utilize municipal sewage sludge (1), including incineration, landfilling, road surfacing, conversion to fertilizer, compression into building blocks, and carbonization (1-4). Since 1976 several patents have been issued on carbonization of sewage sludge and various applications of the final materials (4-7). Carbonization of sludge in the presence o...
متن کاملRemoval mechanisms and kinetics of trace tetracycline by two types of activated sludge treating freshwater sewage and saline sewage
Understanding the removal mechanisms and kinetics of trace tetracycline by activated sludge is critical to both evaluation of tetracycline elimination in sewage treatment plants and risk assessment/management of tetracycline released to soil environment due to the application of biosolids as fertilizer. Adsorption is found to be the primary removal mechanism while biodegradation, volatilization...
متن کاملMunicipal Sewage Sludge Drying Treatment by an Composite Modifier
A sludge composite modifier SCM which comprises a mixture of three cementitious components was proposed for sludge drying and stabilization. Effect of SCM components on sludge moisture content was analyzed using uniform design and the optimum composition of SCM was determined by computer-aided modeling and optimization. To compare the drying effect of SCM, quicklime, and Portland cement, the ef...
متن کاملNitrification Efficiency and Community Structure of Municipal Activated Sewage Sludge
Nitrification is essential to biological processes designed to remove ammonia and/or total nitrogen. It removes excess nitrogenous compound in wastewater which could be very toxic to the aquatic fauna or cause serious imbalance of such aquatic ecosystem. Efficient nitrification is linked to an in-depth knowledge of the structure and dynamics of the nitrifying community structure within the wast...
