Maximizing the utilisation of the nutrient and energy potential of sewage sludge
The Y-MAX project optimizes the sewage sludge treatment process to achieve maximum benefit in nutrient recovery and energy production while minimizing energy consumption.
Recycling energy and nutrients from municipal sewage sludge
Enhancing biogas production of sewage sludge
The energy content of municipal sewage sludge is low and additional sludge treatment, such as nutrient recovery, requires energy.
Additional energy can be added to biogas production by utilising chicken or fish manure. The additional energy can be used in sludge processing. As a transport fuel, biogas significantly reduces transport emissions.
Nitrogen recovery before the biogas process
Chicken and fish manure contain a lot of nitrogen. The project optimises the nutrient content of chicken and fish manure by recovering nitrogen from them before the biogas process. This avoids inhibition due to high nitrogen content in the digestion reactor.
Activities
The Y-MAX project covers the entire value chain of municipal sewage sludge, from sludge to the final treatment of digestate after biogas production. The project studies both dry and wet digestion and the subsequent optimisation of end products to maximize nutrient recovery. The development of real-time monitoring of the process and the monitoring technology play an important role in the project.
The project consists of six work packages:
WP 1. Project coordination and communication
WP 2. Regulations, symbiosis and commercialization
WP 3. Characterization, measurement and monitoring
WP 4. Nitrogen removal and recovery
WP 5. Fraction characterization &; sludge and digestion optimization
WP 6. Digestion disposal and nutrient recovery
