- Under applicable law (The Act on Fertilizers and Fertilization 2007) sewage sludge produced in wastewater treatment plants is treated as waste. The article presents 5 variants of alteration and management of sewage sludge from the wastewater treatment plant in Szamotuły. Some of them include the use of green mass that can be obtained as a result of urban greenery maintenance works. For the purpose of this article there was carried out a quantitative balance of sludge, taking into account different degrees of its hydration. There were also discussed the results of an experiment conducted on the semi-technical scale. The drying process took place under a plastic tunnel with a length of 10 m. Two series of sludge drying at different outdoor temperatures were carried out. The sludge drying time in conditions of high ambient temperatures (24-36˚C) was 18 days. There was also determined the dependance between hydration and drying time at lower temperatures. In the final analysis, there were employed two basic methods of sludge treatment: solar drying and composting. The introduction of new solutions removes numerous existing sludge disposal costs. The benefits will consist in the elimination of sludge disposal costs or sludge hygienisation costs.
