Waste not, want not: In a bid to further discussions about the potential of reusing wastewater to address water shortages across the globe, global water technology company Xylem (Rye Brook, New York) recently showcased a beer made from treated wastewater.

Xlyem partnered with Berlin water utility Berliner Wasserbetriebe and the Kompetenzzentrum Wasser Berlin (the Berlin Centre of Competence for Water) to make what is being called “Reuse Brew.” The drink was showcased at the International Water Association International Conference on Water Reclamation and Reuse in Berlin.

According to Water World, over 2 billion people live in countries with significant water stress, and 4 billion people experience water scarcity at least one month out of the year.

Waste not, want not: In a bid to further discussions about the potential of reusing wastewater to address water shortages across the globe, global water technology company Xylem (Rye Brook, New York) recently showcased a beer made from treated wastewater.

When it comes to sewage treatment in Germany, there are often three steps involved, sometimes four. The fourth step sees the removal of micro pollutants such as medical residues and other materials. To help with this step, Xylem uses ozone and activated carbon, known as the Oxelia process, to eliminate materials oxidized by the ozone and removed by microorganisms. The water is then of high enough quality to be reintroduced to local bodies of water.

To achieve drinking quality, however, another step beyond the Oxelia process must be implemented: An activated carbon filter is used to further filter the water. Reverse osmosis is also used to further amend water quality. The final stage, known as the Advanced Oxidation Process, uses the Xylem MiPRO process with ultraviolet light and hydrogen peroxide.

Previously, Xylem worked with Manchester City and Heineken Manchester to develop “Raining Champions,” a beer made with purified rainwater collected from Etihad Stadium’s rooftop.
