IEEE Transactions on Plasma Science, 2014
This paper presents the results of modeled investigations of a developed sewage sludge (biosolids) plasma treatment complex. This includes a multistage plasma sewage gasifier, high-efficient heat recovery system, and power generation unit based on a gas engine.

Drying Technology, 2006
Dewatering of sewage sludges is usually carried out using belt filter presses or centrifuges. The ability to remove water from sludges by mechanical dewatering is a property of both the sludge and the equipment used for dewatering. Newer high-solids centrifuges can remove more water than a belt press but require a higher chemical conditioning dose. The

Technological characterization of sewage sludge
Waste Management & Research, 1985Laboratory tests for the technological characterization of sewage sludge are catalogued and reviewed. Procedures presently being tested and evaluated by IRSA (Water Research Institute, C.N.R., Italy) are also discussed. Major attention is addressed to the evaluation of sludge dewaterability, since this operation is both expensive and widely utilized ...

Vermitechnology for sewage sludge recycling
Journal of Hazardous Materials, 2009The present paper is aimed at safe reuse and recycling of sewage sludge (SS) and production of good quality compost using vermicomposting. Three different earthworm species Eiseniafetida (E. fetida), Eudrilus eugeniae (E. eugeniae), Perionyx excavatus (P. excavatus) in individual and combinations were utilized to compare the suitability of worm species

Trace elements in sewage sludges
Journal of the Science of Food and Agriculture, 1972AbstractAnalyses of 42 sewage sludges from rural and industrial towns in England and Wales show very large concentrations of certain trace elements. Total contents of 5% Zn, nearly 1% Cr and Cu and 0.5 % Ni were found in certain dried sludges. Total contents of Cu, Sn and Zn and, to a lesser extent, Ag, Bi and Pb were much greater than the levels of ...

Lipid profiling in sewage sludge
Water Research, 2017High value-added reutilization of sewage sludge from wastewater treatment plants (WWTPs) is essential in sustainable development in WWTPs. However, despite the advantage of high value reutilization, this process must be based on a detailed study of organics in sludge.

Characterization of Sewage Sludges
1981Sludge characterization involves description of sludge behaviour in treatment processes and disposal. Appropiate characterization methods facilitate understanding and prediction of sludge properties. The characterization parameters belong to one of three cathegories: Indication of quantity, treatability or quality.

Mycoflora of activated sewage sludge
Mycopathologia, 1976Thirty-eight species of fungi were identified in pure culture after isolation from activated sewage sludge by serial dilution. Nine species and genera were identified that had not been previously reported. In 1963, Cooke (1) published an excellent laboratory guide on the identification of fungi from polluted water, sewage, and sewage treatment systems;

Vermistabilization of primary sewage sludge
Bioresource Technology, 2011An integrated composting-vermicomposting process has been developed for utilization of primary sewage sludge (PSS). Matured vermicompost was used as bulking material and a source of active microbial culture during aerobic activated composting (AAC).

In the United Kingdom, disposal of sewage sludge to the sea is almost entirely by dumping from ships into estuarine and coastal waters. Only very small quantities are discharged by pipeline. In other countries bordering the North Sea, sludge disposal is almost exclusively to land, although some countries, such as the Federal Republic of Germany, have ...
