Experiences obtained in the pyrolysis pilot plant during the Szent István University's pyrolysis research project are described. Eight different raw wastes were treated in a pyrolysis pilot plant in Mezőberény. Test results obtained are suitable as reference in connection with the quality of end products. It is also useful in examining how the environmental emission values of this kind of plants can comply with national legal requirements. By using the objective test results and experiences from operating model conditions, our research group is able to analyze and evaluate test results of a similar system in the following.
The water quality of the Szarvas-Békésszentandrás Dead Körös is generally meso-eutrophic, and meso-saprobic. However, particularlyunder higher temperature conditions, the water body may change toward the eutrophic state, even algal blooms could be observedpreviously.The present measurements were conducted during a two week period, twice a day. Three water samples were taken horizontally, fromthe surface, bottom and the middle of the water body. The samples were examined in situ. The oxygen content, the temperature, the pH andthe conductivity were measured by potentiometric methods.Increasing pH was detected in correlation to the temperature, which indicated a rising photosynthetic activity. Also, the O2concentration showed high variations, especially, when the fresh water supply from the river was stopped, due to a small flood in the riverKörös.These results indicate the increasing eutrophication processes in the deadarm, and the high load and instability of the ecosystem.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
