Sewage sludges are the product of the biological wastewater treatment and their chemical and biological composition varies depending on the type of wastewater and pre-treatment methods. Sewage sludge may be contaminated by pathogenic microorganisms and spores, such as the potentially pathogenic bacteria (Salmonella genus), eggs of intestinal parasites (Ascarislumbricoides, richuris sp., Toxocara sp., etc.) and coliform bacteria (Pseudomonas aeruginosa and Clostridium perfringens), so understanding their ways of development can be difficult, but achievable. To do so, knowledge such as the physico-chemical parameters and microbiological composition of the sewage sludge is needed. Analyzing microbes in sewage slud...
Sewage sludges are the product of the biological wastewater treatment and their chemical and biological composition varies depending on the type of wastewater and pre-treatment methods. Sewage sludge may be contaminated by pathogenic microorganisms and spores, such as the potentially pathogenic bacteria (Salmonella genus), eggs of intestinal parasites (Ascarislumbricoides, richuris sp., Toxocara sp., etc.) and coliform bacteria (Pseudomonas aeruginosa and Clostridium perfringens), so understanding their ways of development can be difficult, but achievable. To do so, knowledge such as the physico-chemical parameters and microbiological composition of the sewage sludge is needed. Analyzing microbes in sewage sludges is important, as the chemical and microbiological contents of the sludges can potentially be improved, in this case, eliminating the heavy metal contents and pathogens.
