Oil and Grease Value Assessment Tool
Oil and grease (O&G) in meat processing wastewater has long been considered a difficult contaminant that must be separated in the primary wastewater treatment system, usually using a Dissolved Air Flotation (DAF) system, and trucked off-site to landfill and/or treated in open anaerobic ponds. In recent years, there has been growing interest by processors in resource recovery or reuse, particularly with regards to O&G.
As the most suitable option for a particular processor is highly depended on site-specific variables, there is no one definitive option that is the best. For this reason, a Value Assessment tool has been developed in Microsoft Excel for use by Australian meat processors through this project.
