Web170215: Is there life after DAF?


A Bioenergy Association and Bioenergy Australia joint webinar.   

Advances in processing high solid / fat food wastes using anaerobic digestion

Currently, the most adopted treatment technology used to process wastewater from the food processing industry is chemically-assisted separation of solids and fats, using a technique known as Dissolve Air Flotation (DAF).  The effluent is either directly discharged, applied on land or polished using aerobic biological treatment withthe separated solids, DAF sludge, being disposed of. DAF is able to achieve high solids separation efficiency but the key challenges for successful DAF operation is an adequate upstream flow buffering while managing odour generation and disposal of the DAF sludge.
