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 کاملHeavy metal removal from municipal sewage sludges by phytoextractio
In European Union countries up to 80% of sewage sludge is used in agriculture and forestry, whereas in Poland only 11% is used as fertilizer. The principal environmental concern is the inevitable presence of heavy metals when using sewage sludge as fertilizer. The main objective of this study is to assess the effectiveness of the phytoextraction process in removing heavy metals from sludges. A ...
متن کاملPresence of enteric viruses in freshwater and their removal by the conventional drinking water treatment process.
A review of results published in English or French between 1980 and 1990 was carried out to determine the levels of indigenous human enteric viruses in untreated surface and subsurface freshwaters, as well as in drinking water that had undergone the complete conventional treatment process. For this purpose, the conventional treatment process was defined as an operation that included coagulation...
متن کاملConcentration of viruses from sewage and excreta on insoluble polyelectrolytes.
The concentration of viruses from sewage by adsorption on and elution from an insoluble cross-linked copolymer of maleic anhydride is described. Viruses either added to sewage or naturally contained in sewage were preferentially adsorbed to this polyelectrolyte at a pH range of 5.0 to 6.0 and were eluted at pH 8.0 to 9.0. In a 2-month survey of viruses in sewage in the spring (April to May 1968...
متن کاملHuman Pathogenic Viruses in the Marine Environment
Indigenous marine virus strains outnumber any form of life in the sea, usually occurring in billion amounts per liter (Danovaro et al., 2001; Fuhrman, 1999). However, although transspecific propagation of viruses may take place, the virus–host relationship tends to be quite constrained, and consequently human viruses are the only viral agents of public health concern in the marine environment. ...
