Slaughterhouse Wastewater Pretreatment with Dissolved Air Flotation Before Biological Treatment
Dissolved air flotation (DAF) is widely positioned upstream of biological reactors in slaughterhouse wastewater trains, where its function is to remove floatable and suspended fractions before the remaining load reaches anaerobic or aerobic stages . In a documented poultry slaughterhouse case, the plant combines a DAF
Treating Cooling Tower Blowdown for Reuse with Reverse Osmosis
One documented route is to route tower blowdown into a softening plant so it can be blended with raw water and then treated. In the OSTI report, all the tower blowdown from two plants was recycled to a makeup water softening plant where it was blended with raw water and the mixture lime-soda ash softened . The same rep
