The main objective of the CELSIUS project is to develop and demonstrate a wastewater treatment system for warm climate areas characterized by low energy consumption. The system proposed is the result of the combination of two innovative treatment processes: Anaerobic Membrane Bioreactor (AnMBR) and Partial Nitrification/Anammox Treatment. The first targets organic matter removal while the second focuses on nitrogen elimination.

The specific objectives of the project:
• To reduce the energy consumption of organic matter removal through the optimization of a mainstream anaerobic MBR. Compared to the conventional treatment processes, this process is expected to reduce 60% of the energy consumption for the organic matter removal.
• To reduce the energy consumption of nitrogen removal through the development of advanced control schemes and appropriate operational strategies for the partial nitrification/anammox process.
• To eliminate the pollution in terms of organic matter and nitrogen from the incoming wastewater.
• To evaluate the feasibility for full-scale application of the optimized system in warm-climate areas such as South America, India, Africa and in European countries in the Mediterranean basin (Spain, Portual, Italy and Greece).
• To transfer the acquired knowledge to stakeholders by means of specific education and dissemination strategies and platforms as well as recommendations to policy makers
