ABOUT THE CLIENT

CARLSBERG BREWERY IN DENMARK

DRIP’s (Danish Partnership for Resource and Water-Efficient Industrial Food Production) goal is to assist in optimizing water consumption across food production processes through the development and implementation of advanced technologies and solutions in Denmark. The collaboration closely involved the Danish Veterinary and Food Administration, the Danish Environmental Protection Agency, and the Danish Agency for Water and Nature Management to provide regulatory guidelines and ensure that they are met. Innovation Fund Denmark was a critical part in terms of providing the necessary funding for the initiative.

WHAT THE CLIENT NEEDED

FUTURE OF BEER BREWERY

ULTRAAQUA UV is proud to celebrate a successful collaboration with Carlsberg’s Fredericia brewery, Niras, and Pantarein Water Bvba on the “Total Water Recycling Plant” project which was initiated by the nationwide public-private partnership DRIP. With the new, advanced water treatment plant, Carlsberg will now be able to re-use 90% of its process water and save 10% more energy. This will help to cut the total water use in half – from 2.9 hl of water per hl of beer to 1.4 hl of water per hl of beer. The new initiative has made the brewery the first in the world to nearly eliminate water waste and has placed Carlsberg above its 2030 sustainability targets.

THE SOLUTION

Advanced Oxidation Process (AOP) and Carlsberg

AOP processes are becoming an increasingly favored solution due to its effectiveness in applications that require a high level of security and sanitation. However, this method is highly versatile, and to achieve the best security results, it requires experience and a tailored treatment approach. At Carlsberg’s brewery, AOP is the last treatment step of the entire treatment plant before being able to reuse the water. ULTRAAQUA UV’s Head of Research and Innovation, Morten Møller Klausen and his team have conducted comprehensive scalable laboratory experiments and process integrated CFD modeling of selected AOPs. The generated data was used to design a UV-based AOP reactor, stabilizing chemical and microbiological water quality and delay aftergrowth potential before storage and reuse.
