A complete sludge treatment reduction process which combines high pressure and temperature.
Thermal hydrolysis heats up thickened sludge at between 150 and 165 degrees Celsius, with a pressure of around seven bars. This improves the biodegradability and viscosity of the sludge, doubling the feed concentration in the digester and enhancing biogas production.
Thermal hydrolysis achieves enhanced treated sludge and improves the final sludge cake dryness. The treated sludge can then be recovered for agricultural use. The increased biogas produced by the anaerobic digestion can be used for producing green electricity or can be injected after treatment in the gas grid.
- Double digester capacity
- Enhanced biogas production for electricity production or grid injection
- Enhanced treated sludge produced
