Food processing wastewater varies by industry but generally has high organic content, suspended solids, and nutrients requiring biological treatment.

Food Industry Wastewater Characteristics

Meat and Poultry

• High BOD and fats, oils, grease (FOG)
• Blood and protein
• Pathogenic organisms

Dairy Processing

• High lactose and protein
• Variable pH
• Cleaning chemical residues

Beverage Production

• High sugar and organic content
• Variable pH
• Color from dyes and pigments

Treatment Approach

Grease Removal

Dissolved air flotation (DAF) for FOG removal. Essential pre-treatment for high-fat wastewaters.

Biological Treatment

Sequencing batch reactors or anaerobic digesters for organic removal. Anaerobic treatment can generate biogas.

Nutrient Management

Denitrification and phosphorus removal for nitrogen and phosphorus control.

Water Reuse

Many food processing operations can reuse treated wastewater for cleaning, irrigation, or cooling.
