Desalination, 2010
Abstract The following article compares different ways of characterising sewage sludge. Against the background of sludge recycling in agriculture as well as treatment with subsequent phosphorus recovery in mind, the article starts by collating and evaluating the levels of phosphorus, heavy metals, chlorine and sulphur in sludge as reported in the ...

Mercury in Municipal Sewage and Sewage Sludge
Bulletin of Environmental Contamination and Toxicology, 2019Wide occurrence of mercury species, including the highly toxic and readily bioaccumulative methylmercury (MeHg), in municipal sewage (MS) and sewage sludge (SS) has been evidenced in recent studies. Considering that vast amounts of MS and SS are produced globally each year and the majority of MS is discharged into aqueous environments, i.e., the main ...

Tijdschrift voor diergeneeskunde, 1987
Current knowledge of sewage sludge is reviewed, particular reference being made to the possible effect on the health of herds of cattle. The following measures should be urgently and seriously considered: more effective watching of sewage disposal; assessments on sewage disposals, related to the costs of alternatives; stricter checks on diffuse sources

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.

Pyrolytic characteristics of sewage sludge
Chemosphere, 2006In this study, a number of different sewage sludge including sludge samples from industrial and hospital wastewater treatment plants were characterized for pyrolysis behavior by means of thermogravimetric analysis up to 800 degrees C. According to the thermogravimetric results, five different types of mass loss behaviors were observed depending on the ...

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;

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 ...

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
