Food and Beverage Wastewater Treatment: Industry Challenges and Innovative Solutions
Focusing on Efficient and Sustainable Industrial Water Management Technologies

Industry Wastewater Characteristics and Challenges

Food and beverage wastewater is characterized by high organic loads (BOD/COD), complex compositions (fats, sugars, proteins), and treatment variability. Wastewater differs significantly across subsectors (dairy, brewing, meat processing, etc.), making traditional methods inefficient and costly.

High Organic Load

COD often exceeds 10,000 mg/L, requiring advanced degradation technologies.

Complex Composition

Fats, suspended solids, and pH fluctuations destabilize biological systems.

Stringent Regulations

Tightening discharge limits for BOD, TN, and TP (e.g., EU IPPC Directive).

Operational Costs

Energy consumption accounts for 15-25% of production costs, demanding energy-saving solutions.

Sector-Specific Solutions and Technical Analysis

Customer Success Cases

  • Dairy Processing Plant Wastewater Treatment

    Background: The dairy processing plant's wastewater contained large amounts of lactose, proteins, and fats, with high BOD and COD values, and oil and grease layers were significant during treatment.
    Implementation Process:
    BOD reduced from 5000 mg/L to 150 mg/L, and COD dropped from 7000 mg/L to 200 mg/L.
    The Roots Blower provided the oxygen required to maintain microbial activity, optimizing the degradation process.
    Overall wastewater treatment efficiency increased by over 90%.
    Result: The wastewater successfully met discharge standards, ensuring a safe production environment and food safety during dairy processing.

  • Brewery Wastewater Treatment

    Background: The brewery’s wastewater contained large amounts of alcohol and other volatile organic compounds, with a low pH. Traditional treatment methods were ineffective.
    Implementation Process:
    BOD and COD were reduced by 85% and 90%, respectively.
    The system efficiently handled the acidic wastewater by using an acid-resistant MBBR system, which allowed for stable microbial activity in low pH conditions.
    Yeast and sugars were effectively removed using the combined Screw Press, reducing the solid impurity load in the effluent.
    The Roots Blower ensured continuous oxygen supply, optimizing microbial activity in the treatment process.
    Result: The brewery’s wastewater treatment efficiency improved significantly, achieving compliance with discharge standards, reducing environmental impact, and ensuring the sustainability of the brewery’s operations.
