Microbial populations and activities in sewage sludge and phosphate fertilizer-amended soil
(Elsevier B.V., 1996-07-01)
A greenhouse study was conducted to determine the number of microbial populations and activities in sewage sludge and phosphate fertilizer-amended dark red latosoil for cultivation of tomato plants. Sewage sludge was applied ...
Concentrations of Cu, Fe, Mn, and Zn in tropical soils amended with sewage sludge and composted sewage sludge
(2013-04-01)
Sewage sludge may be used as an agricultural fertilizer, but the practice has been criticized because sludge may contain trace elements and pathogens. The aim of this study was to compare the effectiveness of total and ...
An evaluation into the potential of biological processing for the removal of metals from sewage sludges
(Crc Press Inc, 1999-01-01)
The use of sewage sludge in agricultural land as a means of sludge disposal and recycling has been shown to be economical and suitable because of the presence of nutrients such as nitrogen and phosphorus. However, municipal ...
Influence of a Brazilian sewage outfall on the toxicity and contamination of adjacent sediments
(Elsevier B.V., 2005-08-01)
The submarine sewage outfall of Santos (SSOS) is situated in the Santos Bay (São Paulo, Brazil) and is potentially a significant source of contaminants to the adjacent marine ecosystem. The present study aimed to assess ...
Functionalization of kaolinite for removal of phosphate from urban sewage
(2021-01-01)
The PO43− widespread in urban sewages promotes eutrophication of water sources, with harmful effects to natural life and endanger human health. The removal of PO43− from urban sewage requires treatment at tertiary level, ...
Thermal behavior of residues (sludge) originated from Araraquara water and sewage treatment station
(Springer, 2009-08-01)
The number of the cities with canalized water and sewage treatment stations has increased lately and consequently having in mind the great concern on environment preservation and the quality of the water used by society. ...
Bioleaching of metals from anaerobic sewage sludge: Effects of total solids, leaching microorganisms, and energy source
(Marcel Dekker Inc, 2001-01-01)
The effects of municipal sewage sludge solids concentration, leaching microorganisms (Thiobacillus thiooxidans or Thiobacillus ferrooxidans) and the addition of energy source (SO or Fe(II)) on the bioleaching of metals ...
Influence of domestic sewage leakage on the collapse of tropical soils
(Springer, 2007-05-01)
In the studied region, 35% of the soil collapses are related to leakage from sewage ducts. The paper describes the soils from this part of Brazil and a series of laboratory tests undertaken using water and domestic sewage ...
Alterations in the fat body cells of rhinocricus padbergi (Diplopoda) resulting from exposure to substrate containing sewage sludge
(2012-04-01)
Abstract The final disposal of residues generated at sewage treatment plants (STPs) has become a major problem for cities, due to the increase in the amount of treated sewage. One of the alternatives for the residue, labeled ...
Evaluation of metal removal efficiency and its influence in the physicochemical parameters at two sewage treatment plants
(2018-05-01)
In sewage treatment plants, physicochemical parameters are highly controlled since treated sewage can be returned to water bodies or reused. In addition, pollutants such as heavy metals also deserve attention due to their ...
