Brewing's Water Challenge

Brewing excellent beer needs clean water, but environmentally conscious breweries aim to minimize water usage. The key lies in saving and reusing water for cleaning, and turning wastewater into a cost-efficient and sustainable resource.

Treating industrial wastewater not only preserves natural resources but also complies with regulations, offering economic benefits. By reusing water, breweries reduce waste, maintain water quality, and save costs.

Sustainable Wastewater Reuse

In the brewing process, water is vital for crafting beer, heating, equipment cleaning and washing bottles and kegs. The wastewater undergoes treatments like anaerobic and aerobic steps, enhanced with ultrafiltration and reverse osmosis.

This ensures water quality for reuse, minimizing discharge and promoting environmental sustainability.

water as a resource

With Pentair X-Flow Wastewater Membrane Technologies, we empower breweries to transform wastewater into a valuable resource, reclaiming up to 70% of water that would have been discarded. Making every drop count for a greener future.

Development of Beer-to-water ratio targets for large scale breweries

Moving from to a 1:10 Beer-to-water ratio in the 1980’s towards a 1:2 ratio for 2023 and beyond.

PENTAIR X-FLOW SOLUTIONS
