Case Study Example
Application: Brewery Water removal from industrial wastewater
Challenge: A manufacturing facility needed to reduce brewery water levels to meet local discharge standards.
Solution: HydroChemix recommended a treatment process using PAC as the primary treatment chemical, combined with pH adjustment and flocculation using PAM.
Results:
- Brewery Water concentration reduced to below discharge limits
- Treatment cost: approximately $0.08-0.15/m³ (chemicals only)
- Treatment efficiency: PAC + DAF: 70-90% COD, 90%+ TSS; TCCA CIP: 99%+ microbial control
- Stable performance across varying influent conditions
Optimizing Brewery Water Removal: Key Tips
- Conduct jar tests — Determine optimal coagulant type, dose, and pH

Frequently Asked Questions (FAQ)
Q1: What is the best chemical for brewery water removal?
The best chemical for brewery water removal depends on the water matrix and target removal rate. PAC is commonly used and achieves PAC + DAF: 70-90% COD, 90%+ TSS; TCCA CIP: 99%+ microbial control. The treatment method typically involves cip water disinfection (tcca). For optimal results, jar testing is recommended.
Q2: How much PAC is needed for brewery water removal?
The dosage of PAC for brewery water removal depends on the initial concentration, target effluent level, and water quality. Typical dosing ranges from 10 to 300 mg/L. A jar test should be conducted to determine the optimal dose for your specific water conditions.
Q3: What is the removal efficiency for brewery water using chemical treatment?
Chemical treatment for brewery water removal typically achieves: PAC + DAF: 70-90% COD, 90%+ TSS; TCCA CIP: 99%+ microbial control. The actual removal rate depends on factors including initial concentration, coagulant type and dose, pH, temperature, and mixing conditions. Optimization through jar testing can maximize removal efficiency.
Q4: What pH is optimal for brewery water removal?
The optimal pH for brewery water removal varies by treatment method. For coagulation with PAC, pH 6.5-7.5 is typically optimal. For precipitation processes, pH may need to be adjusted to 8.5-10.5. Always verify optimal pH through jar testing at different pH values.
Q5: Can activated carbon remove brewery water?
Activated carbon can be effective for brewery water removal, particularly for organic contaminants. The effectiveness depends on the carbon type (coconut shell vs coal-based), mesh size, and contact time. PAC (powdered activated carbon) is dosed at 5-50 mg/L, while GAC (granular activated carbon) is used in fixed beds with EBCT of 10-30 minutes.
Q6: What are the treatment methods for brewery water in water?
Common treatment methods for brewery water include: cip water disinfection (tcca); brewery wastewater coagulation (pac/pam); daf for fog removal; activated carbon polishing. The choice depends on the contaminant concentration, water quality, target removal efficiency, and cost constraints. Chemical coagulation is often the most cost-effective first step.
Q7: How much does brewery water removal cost?
The cost of brewery water removal varies based on the treatment method and scale. Chemical treatment costs typically range from $0.02 to $0.20 per m3 of water treated, including coagulant, flocculant, and energy costs. For large-scale treatment, bulk chemical purchasing can significantly reduce costs.
Q8: What are the discharge limits for brewery water?
Discharge limits for brewery water vary by jurisdiction and receiving water body. Typical limits range from 0.1 to 2.0 mg/L for most contaminants, with stricter limits for drinking water sources. Check local environmental regulations (EPA, EU, CPCB, or equivalent) for specific requirements.
Q9: How do I choose the right chemical for brewery water removal?
To choose the right chemical for brewery water removal: (1) Analyze water quality (pH, TSS, initial concentration), (2) Conduct jar tests with 2-3 coagulants at various doses, (3) Measure removal efficiency and settleability, (4) Calculate cost per m3, (5) Consider sludge production and disposal.
