Background. Water usage during beer production is one of the highest in the food processing industry. The dynamically growing microbrewery market requires the implementation of water recycling systems. The research investigated and presented the technology for the recovery of rinse water from the brewing industry. A case study examined the usage of water during the brewing and cleaning process in a small brewery. Moreover, an analysis of brewery rinse water before and after purifying was conducted.
Results and conclusions. The purified water obtained had high technological values, including lower turbidity, reduced content of nitrates and over two-fold increased content of chlorides and met the requirements for drinking-grade water. The implementation of the analyzed system may both provide financial benefits and ensure compliance with sustainable development trends initiated by the largest breweries. The design and features of the analyzed purifying system make it possible to use it commercially in the microbrewing industry.
