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

Stabilization of heavy metals in fired clay brick incorporated with wastewater treatment plant sludge: Leaching analysis
Aeslina Abdul Kadir,Mohd Ikhmal Haqeem Hassan,Nurul Salhana Abdul Salim,Noor Amira Sarani,S. Ahmad,Nur Aqma Izurin Rahmat +5 more
TL;DR: In this article, the authors used X-ray fluorescence to determine the heavy metals concentration of wastewater treatment sludge and found that 20% of the sludge incorporated into the brick is the most suitable for building materials as it leached less heavy metals and complying with USEPA standard.

Enhanced Production of Methane from Waste Activated Sludge by Pretreatment Using a Gas Diffusion Cathode
TL;DR: In this article, an electrochemical system characterized by a gas diffusion cathode (GDC) was established to facilitate WAS pretreatment, which was composed of a carbon black diffusion layer and a Ni/NiOx catalytic layer.
Dissertation
An experimental and modelling investigation of wet oxidation of municipal biosolids
TL;DR: In this paper, the authors describe the development and validation of detailed kinetic models describing the wet oxidation of municipal biosolids, which are produced by wastewater treatment plants and are becoming increasingly important because current disposal methods are not sustainable.

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.
Book
Wastewater Engineering Treatment Disposal Reuse
TL;DR: Wastewater Engineering: An Overview of Wastewater Engineering, Methods and Implementation Considerations as mentioned in this paper is a good starting point for a discussion of the issues of wastewater engineering. But, it is not a complete survey of the entire literature.

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.
