Winemaking Process
• Harvest and Crush • Fermentation • Clarification and Racking • Filtering and Bottling
© Orenco Systems, Inc. #4
Harvest and Crush
© Orenco Systems, Inc. #5
Harvest and Crush •Grapes are picked, de-stemmed and crushed
© Orenco Systems, Inc. #6
Fermentation •Yeast is added to convert sugars to alcohol
© Orenco Systems, Inc. #7
Clarification and Racking Wine is siphoned off the lees into new, clean barrels

Filtration and Bottling

Application Types
•Boutique or Mass Produced •Process Waste and Sanitary Waste •Dispersal
© Orenco Systems, Inc. #10
Boutique Wineries
•Production is typically 10,000 cases per year or less

Design Flow Calculations
•2.378 gallons of wine per case •6 gallons of wastewater generated per gallon of wine produced per
year •1.5 gallons of that 6 gallons is produced during crush •Crush is typically 30-60 days
Wineries measure in Cases of Wine per year

Design Flow Calculations •Gallons of wastewater/season = number of cases * gallons/case *
estimated gallons of wastewater discharge/case
•Gallons/day = gallons/season / number of days in season •Example:
∼ 20,000 cases/season * 2.4 gallons wine/case * 1.5 gallons wastewater/gallon wine = 72,000 gallons watewater/season.
∼ 72,000 gallons per season / 60 days per season = 1,200 gallons/day.

BOD Assumptions •Winery process wastewater can exceed 30,000 mg/L BOD5 •Typical process waste averages:
∼ 3,000 – 7,000 mg/L BOD5 ∼Design BOD5 = 7,000 mg/L • Typical Domestic Waste Strength: around 300 mg/L
