[032] Local wastewater treatment systems – a solution for Motor Rest Areas sewage purification?

My name is Kinga Marek. I was born on 3rd of october in 1997. I live and conduct my research in Wrocław, where I am also a PhD student. So far, I have finished my engineering and master's studies at the Wroclaw University of Environmental and Life Sciences. This is also where I am currently carrying out my work, specializing in environmental engineering, mining and energy, and more specifically in sanitary technology. My research is based on the study of the composition of wastewater, I deal with those sewage that are characterized by a high content of ammoniacal nitrogen. In addition, I plan to find a suitable solution that will cope with the elimination of pollutants from wastewater. I made a few articles on the topic presented above. Currently, I also conduct research on sewage granulometry and analyze the shape of particles in various types of sewa.

Due to the expansion of highways and expressways, there is a need to provide sanitary facilities for travelers. They can be located on so called Motor Rest Areas (MRA) equipped with parking spaces. The use of sanitary facilities is connected with the need of generated wastewater purification. One of the solution for MRA wastewater treatment is the use of local sewage treatment facilities when connection to the sewerage is not possible. Sewage from Motor Rest Areas cannot be treated as domestic wastewater because of their characteristics. The aim of this study was to assess the possibility of treatment of sewage generated on MRA with the use of traditional local wastewater treatment plant based on mechanical and biological treatment. Wastewater samples analyzed in this study were taken from 4 MRAs located on the expressway. The COD/BOD5 ratio higher than 1.8 might indicate lack of easily accessible organic matter and can negatively affect biological sewage treatment. Concentrations of total nitrogen (TN) and ammonium nitrogen presents very high ratio of N-NH4 to TN. The total nitrogen and phosphorus removal efficiency is very low. High ammonium concentrations in sewage strongly affects possibility of their biological treatment causing an increase in the alkalinity of wastewater and thus - disinfecting effect on microorganisms in the active sludge. Presented results of research conducted on MRAs shows that traditional local wastewater treatment plant does not provide a sufficient level of purification. The solution to this problem may be to separate the stream of urine. Purification of wastewater with high ammonium concentration is still a unsolved problem and requires the search for new solutions.
