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

The synergistic effect during co-combustion of municipal sludge and coal: Experimental and ReaxFF molecular dynamic study
TL;DR: In this article , the authors investigated the behaviors of municipal sludge/coal co-combustion by experiments and ReaxFF molecular dynamic simulations and found that coal combustion was promoted by some ·OH radicals produced by the sludge attacked the aromatic ring structure in coal and accelerated the formation of carbonaceous gas.

Tratamiento de residuos y subproductos agroindustriales mediante co-digestión anaerobia
TL;DR: The biometanización de residuos organicos of the sector agricola e industrial permite tratar, de manera individual or conjunta, dichos residueros, with the ventaja adicional de reducir su contenido in materia organica, transformandola principalmente en metano, which is un compuesto de elevado poder calorifico cuya combustion no contribuye al efecto invernadero cuando procede de recursos renovables.

A study on the improvement of sludge dewaterability by thermal conditioning
TL;DR: In this paper, the main factors affecting sludge dewaterability by thermal conditioning are experimentally investigated and the results show that the major factors for improving sludge degradation are conditioning temperature and residence time.

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.

Sewage sludge combustion
Joachim Werther,T. Ogada +1 more
TL;DR: In this article, a review of the current and future issues related to the combustion of sewage sludge is presented, and a number of technologies for thermal processing of sludge are discussed in three groups, i.e., mono-combustion, cocombustions and alternative processes.

Trace metal analysis on polluted sediments
Ulrich Förstner,Wim Salomons +1 more
TL;DR: In this article, the authors proposed a standardization with respect to grain size effects, commonly achieved by analyzing the sieve fraction <63μm, which is used to pin point major sources of metal pollution and to estimate the toxicity potential of dredged materials.
