Additional Digesting stage Houtrust

Ontwaterd slib silo’s - Houtrust

WWTP Houtrust has an overcapacity in the digester installation, after WWTP Harnaschpolder became operational. Under the present conditions, only one digester will have to be operational, making the other digester superfluous. By introducing a second digesting stage, the gas production can be increased, making use of the available second digester.
