https://doi.org/10.4467/2353737XCT.14.323.3411This paper presents the variability of the quantity and specific composition of the sludge produced at two different surface water treatment plants ‒ the Raba water treatment plant (WTP), collecting water from an artificial reservoir; and the Rudawa WTP, collecting running surface water. The authors analyzed the differences in the amount and characteristics of sludge and tried to relate them to specific technological systems in use at the treatment plants. The paper mainly focuses on heavy metals removed from the water and then trapped in the sludge. The aim of the work was to describe changes that involved both the quantity of sludge and its characteristics, especially with respect to its further disposal (e.g. heavy metals, etc.). Additionally, some aspects of an activated carbon dosing regime and its impact on a heavy metal content in sludge were discussed.

https://doi.org/10.4467/2353737XCT.16.193.5942The paper analyses the share of single SBR in the total energy consumption of the studied wastewater treatment plant. The analysis is based on a two sets of data measurements, gathered by an automated measuring installation and data archived manually by the plant’s operator. Energy consumption was also analyzed with reference to the archive data of daily flows. The paper is based on data collected from November of 2015 to January of 2016. This is a continuation of an ongoing research.
