Efficiency Aspects of Durres Wastewater Treatment Plant

The sewage system in the city of Durres has been a problem for both residents and ecosystems for years. Urban wastewater had direct effects into surface water, mainly in the Adriatic Sea, and this problem raised the need to build a wastewater treatment plant. The main purpose of this study is to give some aspects of the effectiveness of this wastewater treatment process which is one of the byproducts produced by human activity with a negative impact on all components of the environment. The study presents the description of the study area, the sewage system and the impact of this project on the environment. It is described the functioning of the urban wastewater treatment plant, the working methods followed, and the laboratory analyzes performed to maintain control of this process according to state-set standards. The discussion of the biological and chemical results obtained in the laboratory, are based on data obtained from: determination of wastewater and clean water entering the plant, the equivalent population to which this plant serves, the amount of phosphorus that has to be reduced, effectiveness of the process for total dissolved solids, as well as effectiveness of parameters on output and wetland.
