PROCESS FOR BREAKING AND WORKING-UP OILY AND FATTY EMULSIONS

摘要

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.
