Sewage and Sewage Sludge Treatment
2013Sewage from properties and industries which are connected to the public sewerage system are treated by physical, chemical and biological sewage treatment processes to protect human health and the environment. In this chapter the conveyance of sewage to treatment works by combined or foul sewers is described.

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).

Sewage sludge disintegration by electrocoagulation
International Journal of Environmental Health Research, 2018In this research, reduction of sludge production and improvement of sludge stabilization degree were aimed, and in this regard, the samples received from an urban wastewater treatment plant were subjected to electrocoagulation (EC) as a disintegration technique.

Keratinolytic fungi in sewage sludge
Mycopathologia, 1996Sewage sludge from the Upper Silesia Region of Poland were surveyed for keratinolytic fungi. Out of 100 Petri dishes examined, 89 were positive for these micro-organisms. Altogether, 185 fungal appearances belonging to 10 species were observed. Trichophyton terrestre with its teleomorph Arthroderma quadrifidum, T. ajelloi with A. uncinatum, Microsporum

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 ...

Phragmites australis for sewage sludge stabilization
Desalination, 2009The purpose of this paper is to determine the effectiveness of a reed bed sludge treatment system in Italy after 1 year of operation in two urban wastewater treatment plants, where Phragmites australis was planted directly in emergency beds rearranged for the project. To evaluate the process of stabilization of the sludge parameters were detected which

Alkaline recovery of phosphorous from sewage sludge and stabilisation of sewage sludge residue
Waste Management, 2019The alkaline leaching of Phosphorous (P) from sewage sludge (SS) using either NaOH or KOH was investigated. The effect of type and concentration of alkali, solid liquid loading and leaching temperature were also investigated. The possibility to stabilise the leached SS residue via geopolymerisation was also explored. The results showed that KOH leached
