Bakery, cookies and crackers
The industrial complex produces famous cookies and crackers commonly found in household pantries. Rinsing and sanitizing the mixers, kettles, and work areas in the facility generates a relatively small volume of wastewater, however the organic ingredients in the water contribute to high levels of TSS, COD, and BOD.
A dual-stage DAF system was supplied with the first DAF recovering suspended, organic materials without the addition of any chemicals and the second DAF removing colloidal solids with chemical aid to meet discharge permit requirements. This dual stage approach reduces sludge volume and allows for separate sludge disposal rates.
