Danish Brewery Improves Wastewater Treatment By Optimizing Nutrient Dosing

Danish brewery, Harboes Bryggeri A/S, faced challenges with its wastewater treatment plant due to high variability in the Chemical Oxygen Demand (COD) load in the inlet. This variability made it difficult for the brewery to meet discharge limits, resulting in the need for external nitrogen dosing. To improve performance and compliance, Harboes Bryggeri A/S implemented measurement solutions from Hach.

One of the key solutions implemented was online Total Organic Carbon (TOC) measurement, which provided real-time data on the organic content of the wastewater. This allowed the brewery to optimize nutrient dosing and improve process stability. Additionally, ammonia and nitrate analyzers were installed to accurately measure these parameters in the wastewater. This data was then used to fine-tune the nutrient dosing, further improving compliance and reducing the risk of fines.
