| Temperature | < 38°C | < 30°C | < 30°C | < 30°C | < 30°C |
| Nitrogen (Total) | < 50 mg/L | < 15 mg/L | < 18 mg/L | < 20 mg/L | < 8 mg/L |

Note: Limits vary by local authority, receiving water sensitivity, and treatment plant capacity. Always consult your local water authority for specific requirements. Trade waste agreements typically set stricter limits than general discharge standards.

Measures the amount of oxygen consumed by microorganisms decomposing organic matter. High BOD indicates high organic pollution.
Brewery sources: Milk solids, whey, lactose, proteins, fats
Measures the total oxygen demand of both biodegradable and non-biodegradable organic compounds. Higher than BOD for brewery waste.
Typical ratio: COD/BOD = 1.5-2.0 for brewery
Measures solid particles suspended in wastewater. Includes fats, proteins, and other insoluble materials from brewery processing.
Brewery sources: Curd particles, fat globules, protein aggregates
Measures lipid content that can cause blockages and interfere with advanced biological treatment. Critical parameter for brewery wastewater.
Brewery sources: Butterfat, cream, milk fat
Measures total nitrogen including organic nitrogen, ammonia, nitrite, and nitrate. Important for eutrophication control.
Brewery sources: Proteins, urea, cleaning chemicals
Measures phosphorus content which contributes to algal growth in receiving waters. Strictest limits in sensitive areas.
Brewery sources: Milk phosphates, cleaning agents
Brewery and beverage wastewater equipment compliance with AS 1210, AS/NZS 4020 and Australian state EPA requirements.
