TECHNICAL PROGRESS
- Experimental campaign at ACEA site
The preliminary tests of compost hydrolysis have been started by employing an old reactor (LIFECAB prototype) as a contingency plan due to delays in the construction of the LIFEEBP prototype. Furthermore, the BP and IR separation and drying system is currently being tested and optimized by HST and ACEA.
In these tests, the sludge in PIV-024 of ACEA plant was employed as raw material with water and KOH in order to reach the optimal conditions for the hydrolysis process. The process is being carried out at 90 °C and a pH equal to 13 to produce 1 m3 of hydrolyzed product per batch. The obtained product is being characterized by partners to determine its suitability for the aims of the project.
The prototype tested during this campaign is shown in the following figure:
After the optimization of the membrane process, the hydrolyzed MBW will be dried employing the Comber Shell Turbo dry (See picture below). This dryer is capable to remove up to 0.7 m3/day of water from the BPs. The process will be optimized at HST premises by April 2022, before delivering it to ACEA premises.
