Application of chemometric methods in the evaluation of chemical and spectroscopic data on organic matter from Oxisols in sewage sludge applications
(Elsevier B.V., 2010-02-15)
Chemometric methods can contribute to soil research by permitting the extraction of more information from the data. The aim of this work was to use Principal Component Analysis to evaluate data obtained through chemical ...
Solubilization profiles of metal ions from bioleaching of sewage sludge as a function of pH
(Kluwer Academic Publ, 2002-04-01)
Two patterns of solubilization of metal ions resulting from bioleaching of sewage sludge by sulphur-oxidizing Thiobacillus spp. were established as a function of pH. Chromium and copper ions required a pH of 2-3 to initiate ...

Characteristics of WWTP sludge after drying in greenhouse for agricultural purposes
(IWA PUBLISHINGLONDON, 2012)
The sludge generated by sewage treatment which meets regulatory standards can be used in agriculture. With this understanding, the focus of this study is the evaluation of the agricultural characteristics and inorganic ...
Agronomic Traits of Corn Fertilized with Sewage Sludge

Chemical characterization of sewage sludges in chile and their potential utilization as amendment to reclaim soils for forestation purposes
(TAYLOR & FRANCIS INC, 2007)
Soils open for forestation in Chile are characterized by their very low organic carbon content; therefore, new forest plantations, needed to restore soil ecological equilibria, are scarcely developed. Stabilized sewage ...
The drying of sewage sludge by immersion frying
(Brazilian Soc Chemical EngSao PauloBrasil, 2005)
Use of municipal and industrial sludge in agricultural soil: Responses of soil microbials and soil enzymes
(2009-04-01)
Industrialization has contributed to the increase in the generation of potentially toxic solid residues. Textile and tannery industries produce residues, called sludge, with high organic and inorganic content, including ...
Mathematical Modeling of Thermal Drying of Facultative Pond Sludge
(Asce-amer Soc Civil Engineers, 2018-09-01)
This study investigated the sludge drying from a facultative pond in a dryer that employs two dehydration methods: thermal drying by infrared lamps and convective drying. For the tests, three thicknesses of sludge were ...
Use of Sludge as Ceramic Materials
(Trans Tech Publications Ltd, 2010-01-01)
Nowadays, with increase amounts of sludge derived from the treatment of domestic sewage put pressure into research on systems for the adequate use of these materials. The aim of the present work is to study the use of ...
