ABSTRACT

The wastewater treatment plant (WWTPD) located in Durrës, responsible for a treatment area of 205,000 inhabitants, employs the tertiary advanced wasterwater treatment to generate biogas from activated 155 sludge for self use. The biogas collected from the anaerobic digestion tank feed the boiler and the co-generation unit which is then transformed to power its own energy grid. In order to evaluate the quality of biogas produced by anaerobic digestion of WWTPD’s sludge, is measured the percentage of CH4 and CO2 from the biogas production during a three years period (2016 – 2018). From the performed analyses has resulted a percentage of CH4 up to 75% and 25% CO2 in 2016. While the lowest percentage of CH4 in 2018 with respectively 70% CH4 and 30% CO2. Based on the value measurements, qualitative results of biogas parameters show that physicochemical and biochemical processes are performed under strict conditions and anaerobic digestion is performed according to standards.
