TLDR
In this article, the authors review past and future trends in sludge handling, focusing mainly at thermal processes (e.g. pyrolysis, wet oxidation, gasification) and the utilization of sewage sludge in cement manufacture as a co-fuel.Abstract:
The European Union has made progress in dealing with municipal wastewater in individual countries and as a corporate entity. However, it intends to make still further and substantial progress over the next 15 years. Currently, the most widely available options in the EU are the agriculture utilization, the waste disposal sites, the land reclamation and restoration, the incineration and other novel uses. The selection of an option on a local basis reflects local or national, cultural, historical, geographical, legal, political and economic circumstances. The degree of flexibility varies from country to country. In any case sludge treatment and disposal should always be considered as an integral part of treatment of wastewater. There is a wide range of other uses for sludge, which exploit its energy or chemical content, namely the thermal processes. The present paper sought to review past and future trends in sludge handling, focusing mainly at thermal processes (e.g. pyrolysis, wet oxidation, gasification) and the utilization of sewage sludge in cement manufacture as a co-fuel.read more

Effect of lime addition during sewage sludge treatment on characteristics of resulting SSA when it is used in cementitious materials
TL;DR: If sludge incineration is accepted solution, lime addition during sludge treatment is unnecessary even from the standpoint of preserving the pozzolanic properties of the resulting SSA, research carried out on cement mortars point to the great possibilities of using SSA in concrete industry.

Opciones de valorización de lodos de distintas estaciones depuradoras de aguas residuales
TL;DR: In this paper, the authors analyzed digested sludge coming from seven different wastewater treatment plants belonging to an industrial estate in Spain and found that heavy metal, Cl, F, C, N and S content is compulsory to estimate atmospheric emissions generated during their incineration.

Exploring PCDD/Fs and potentially toxic elements in sewage sludge during smouldering treatment.
TL;DR: In this paper , the authors investigated the effect of smouldering on the emissions of sludge in a commercial incinerator and found that weak smoulders had low levels of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) and PTEs in the mixture before and after treatment as well as in process emissions.

Sequential extraction procedure for the speciation of particulate trace metals
TL;DR: In this paper, an analytical procedure involving sequential chemicai extractions was developed for the partitioning of particulate trace metals (Cd, Co, Cu, Ni, Pb, Zn, Fe, and Mn) into five fractions: exchangeable, bound to carbonates, binding to Fe-Mn oxides and bound to organic matter.
