Heavy metals in sewage sludge were classified into three partitions associated with extracellular and intracellular organic matters and the residue before and after different elution processes of heavy metals from the sludge. Alkalization of the sludge to pH 11 decreased the content of Cu in the three partitions and that of Ni in extracellular organic and residual ones. Acidification of the sludge to pH 3 decreased the content of Cd, Mn, Ni and Zn in all of the partitions and that of Cu in the… Expand
Treatment of Excess Sludge Containing Heavy Metal by Chemical Ways
The concentration of heavy metals in excess sludge from municipal wastewater treatment plants has restricted its convertion to soil fertilizer, so it is necessary to remove the heavy metals fromExpand
Analysis of the Mobility of Heavy Metals in Sludge for the Sewage Treatment Plant in Daleszyce
Abstract Sewage sludge is a by-product of wastewater treatment processes. However, it has high fertilising and soil-forming properties, but it cannot always be used for this purpose. The two mainExpand
Changes in material flows, treatment efficiencies and shifting of environmental loads in the wastewater treatment sector. Part I: Case study of the Netherlands
TLDR
The paper presents a case study on the wastewater treatment plants in the Netherlands, examines how the degree of separation of COD, nitrogen, phosphorus and heavy metals from the wastewater have increased over time, and studies the changes in proportions separated out to the atmosphere and lithosphere.

Changes in material flows, treatment efficiencies and shifting of environmental loads in the wastewater treatment sector. Part II: Case study of Norway
In Part I, the wastewater treatment sector in the Netherlands was analyzed to determine how the degree of separation of COD (BOD), nitrogen, phosphorus and heavy metals from the wastewater increasedExpand

TLDR
Results suggest the feasibility of recovering ESP from waste sludge for use as adsorbent and correlated satisfactorily with the adsorption data of Ni2+, Cu2+, Cd2+, and CrO4(2-) (R2 ranging 0.89-0.97), whereas Langmuir isotherm correlated poorly for those of Co2+. Expand

TLDR
Steaming treatment was the most effective extraction method for the activated sludges, since it released a significant quantity of extracellular polymers from the flocs and caused less cellular disruption than ethylenediaminetetraacetic acid and sodium hydroxide treatments. Expand

TLDR
The present study arose from the observation that a more intense colour was sometimes produced if, instead of being heated at 1000 for 10 min., the reaction mixture was allowed to stand overnight at room temperature. Expand
