https://doi.org/10.4467/2353737XCT.15.357.4822The article discusses problems related to intensification of anaerobic digestion of sewage sludge. The authors have analysed the principal indicators of a methane digestion process, focusing mainly on biogas production. The most commonly used methods of sludge disintegration were reviewed. Additionally, the methods of algae biomass processing for biofuels and a methanogenic potential of the biomass were presented. The article presents the literature review to identify the possibilities of energy profit caused by using algae in anaerobic digestion of sewage sludge.

https://doi.org/10.4467/2353737XCT.18.009.7960This paper presents characteristics of the Biovac® wastewater treatment plants operating in the mountain areas of the Polish national parks (NP): Tatrzanski NP and Babiogórski NP as well as in the West Spitsbergen NP. On the basis of the laboratory tests performed on raw sewage and the final effluent the efficiency of the wastewater treatment plants was evaluated. It was found that high COD values and rather high COD / BOD5 ratios were observed in the raw sewage during an off-peak tourist season. The research has also shown that the Biovac® treatment plants (SBR technology) showed a high level of removal of pollutants from sewage discharged from mountain hostels.
