Sewage sludge coke estimation using thermal analysis
(Springer, 2011-11-01)
The imposition of more stringent legislation by CETESB in the State of So Paulo (Brazil) governing the disposal and utilization of sewage sludge, coupled with the growth in its generation has prompted a drive for alternative ...
Thermal characterization of granular sludges from biologic treatments and its application to the generation of biogas
(Springer, 2019-12-01)
The application of granular sludge from biological treatment plants can become an economically and environmentally viable process as a renewable source of energy. It is available in most countries, and its application can ...
Quality of surface water and generation of sludge at water treatment plantsQualidade de água superficial e geração de lodos em estações de tratamento de água
(2020-01-01)
Among the waste produced daily by communities are those resulting from the treatment of water for public supply, with local specificities that reflect the characteristics and uses of the land. Despite the continuous ...
Effect of anaerobic digestion and initial pH on metal bioleaching from sewage sludge
(Taylor & Francis Inc, 2006-02-01)
The effects of anaerobic digestion and initial pH on the bioleaching of metals from sewage sludge were investigated in shake flask experiments. A strain of Acidithiobacillus thiooxidans was employed in the assays using ...
Microorganisms in sewage sludge added to an extreme alkaline saline soil affect carbon and nitrogen dynamics
(2012-11-27)
There are plans to vegetate soil of the former lake Texcoco and use wastewater sludge to provide nutrients.
However, the Texcoco soil is N depleted, so the amount of N available to the vegetation might be
limited and the ...
Thermal behavior of residues (sludge) originating from the sugarcane industry
(Springer, 2011-12-01)
The Brazilian sugarcane industry shows a great amount of generated sludge which should be utilized adequately. Two sludge samples, aerobic and anaerobic, were collected. Both were evaluated by thermogravimetry and differential ...
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 ...
