Various steps in the brewing process consume water, not only as an ingredient but also for cleaning and rinsing.
De Leite brewery did not have a clear view of the water use and its efficiency.
BOSAQ performed a detailed water audit, in which our experts measure and analyze the water use throughout the entire production process.
This audit revealed that the water-beer ratio varied between brewing batches (Figure 1). Bigger batches of beer showed a lower water-beer ratio, which indicates that there was a big share of fixed water use linked to cleaning.
It was also found that inefficient use of cooling water amounted to a substantial share of the total water use.
BOSAQ proposed several implementations to reduce water use at De Leite.
In the end, the proposed actions were digested in an implementation plan to unburden the client.
