Carlsberg taps into process water reuse with onsite treatment
arrow_backTo the overview22 September 2022 | Grundfos
Carlsberg brewery wants to cut its water use by 50% by 2030. The initiative, Zero Water Waste, is part of Carlsberg’s Together Towards Zero program. In its production facility in Fredericia, Denmark, Carlsberg has developed a Total Water Management treatment plant with consultants, universities and technology providers like Grundfos. The onsite facility treats used process water from mainly cleaning purposes, purifies it to drinking water quality and sends it back to the brewery to be reused as process water. The plant recovers and reuses 90% of its process water.
REUSING 90% PROCESS WATER
The TWM plant has a daily capacity for 2,000 m3 of incoming process water, of which 90% – or 1,800 m3 – is recovered and recycled. Grundfos pumps and dosing systems cover 95% of the pumps on site, helping along every step of the process, says Andreas Kirketerp, Manager of the TWM plant. The brewery relies on the process water to operate, so pump and system reliability is vital.
Outcome:
90% of process water reused
after treatment – or 1,800 m3/day
Water savings 560,000 m3/year
Proven technology ready for
scale-up in water-scarce regions
