spended solids are flocculated and floated off and removed by a skimmer.
The Flotate sludge is collected in an integral hopper and pumped to a storage tank where it is dewatered using an automatic Huber Screwpress. The DAF plant achieves a 60-65% reduction in COD and a 92-95% reduction in Fats Oils and Greases (FOG) going to the sewer.
The Screwpress takes the 9-11% dry solids flotate and presses these to achieve a cake of ~35-45% dry solids. The filtrate is returned to the buffer tank and ret
