Abstract
It is proposed to demulsify and convert emulsions of oils, greases, and fats in that these emulsions are processed together with digested sludge or sludge liquor from a biological sewage treatment plant. The emulsions of oils, greases, or fats are fed after a first digesting step and preferably to a separate container. In that second digesting step, the bacteria growing under anaerobic conditions can convert much larger quantities of emulsions and the emulsions can be converted within a shorter time.
