Wastewater treatment plants for breweries - Food and Beverage - Beverage
Brewery wastewater is generally polluted with two different classes of pollutants. In the direct brewing process, biological substances such as yeasts, starch or sugar compounds are increasingly introduced into the wastewater. By cleaning brewery plants (boilers, pipelines, etc.) and washing empties, large quantities of chemical cleaning detergents are also discharged into the wastewater of breweries.
Some large breweries use special wastewater treatment processes to recycle substances such as diatomaceous earth and return them to the production process. Wastewater treatment plants that significantly reduce the environmental impact of discharging wastewater into municipal wastewater systems (indirect discharge) are also becoming important in this context. This is often required by the operator of the municipal wastewater treatment plant.
In addition, this method is often very cost-effective, as breweries with their own wastewater treatment plants often save on very high discharge fees. Important parameters for brewery wastewater are nitrogen and biochemical oxygen demand (BOD).
