Food Processing Wastewater Treatment in Thailand | Efficient Color & COD Removal Solution
Food Processing Wastewater Treatment in Thailand | Efficient Color & COD Removal Solution
2026-03-24
1. Background & Challenge
Thailand is one of Southeast Asia’s leading food processing hubs, with strong production in sauces, beverages, and fermented products. These industries generate wastewater characterized by:
High organic content (COD & BOD)
Yellow to brown coloration from natural organics
Suspended solids and unstable settling
Odor issues during storage and treatment
The client faced difficulties in achieving consistent clarification and discharge compliance, especially during peak production periods.
2. Bluwat Treatment Approach
After evaluating the wastewater sample, Bluwat recommended a stable and flexible treatment program:
Step 1: Add PAC (Primary Coagulation)
Quickly neutralizes charge and aggregates suspended solids.
Step 2: Adjust pH (if required)
Ensures optimal coagulation conditions.
Step 3: Add PAM (Flocculation)
Forms strong, large flocs for efficient solid-liquid separation.
Optional Step: Add Decoloring Agent
Used when color removal requirements are higher.

7. FAQ (Food Industry Focused)
Q1: Is this treatment safe for food industry wastewater?
A: Yes, the chemicals are widely used in industrial water treatment and can be applied safely with proper dosing control.
Q2: Do I always need a decoloring agent?
A: Not always. For most food wastewater, PAC + PAM is sufficient. Decoloring agent is used when color is high.
Q3: Can this reduce odor as well?
A: Yes, by removing organic matter, odor can be significantly reduced.
Q4: How stable is the treatment process?
A: Very stable, even under varying wastewater loads.
Q5: Can you test our wastewater sample?
A: Yes, Bluwat offers lab-scale testing and tailored solutions.
