The project was part of the DKTI (Deutsche Klima- und Technologie-Initiative) program “Clean Technology Initiative of the German Government” which is a line of specific investments to mitigate greenhouse gas emissions in countries that are part of the international cooperation with Germany in various economic sectors. The DKTI investment line covers the official technical and financial cooperation between Germany and Brazil, focusing on energy efficiency and the mitigation of greenhouse gases through the biogas capture and its use in WWTP. The project consisted of three components:
- Component 1: Technical studies for the three WWTP Vitória da Conquista, Jacuípe I and Subaé focusing on biogas reuse from the gas produced in UASB (Upflow Anaerobic Sludge Blanket ) reactors and energy efficiency
- Component 2: Technical-economic analysis of an additional secondary treatment of three projected WWTP (Brumado, Camaçari and Bacia Pojuca). Compared treatment process were UASB + Trickling filter, UASB + activated sludge and for Brumado UASB + constructed wetlands
- Component 3: Study on the centralized or decentralized sludge treatment for the three existing WWTPs Jacuípe I & II and Subaé and the new WWTP Bacia Pojuca
