Wastewater treatment plants for breweries

The industrial wastewater from breweries usually comes from the cleaning of production facilities and can contain coarse materials such as
cullet, labels, spent grains and crown corks.

Strong fluctuations in wastewater volumes and loads as well as pH values can occur over the course of a week.
In principle, the water is considered to be readily biodegradable due to its favorable COD/BOD ratio, although the inflow concentrations are higher than for domestic wastewater (BOD5 values of up to 4,000 mg/l).
