Case study – industrial and lab tests

Lindum biogas plant, Drammen, Norway.
THP before digester.
Feedstock: sludge + grease +fish ensilage

Objectives

How does our frequent feeding laboratory system compare to an industrial system using the same feedstock?
Can an industrial AD process tolerate pyrolysis condensate (PC) from its own biosolids?
How is methane production affected?
How does PC affect the quality of the reject water after dewatering?
