Carlsberg brewery wants to reduce its #waterfootprint by 50% and eliminate wastewater discharge by 2030. In its production facility in Fredericia, Denmark, it has developed – with consultants, universities and technology providers like Grundfos – a Total Water Management (TWM) treatment plant for #waterreuse. Onsite, the facility treats its used process water from mainly cleaning purposes, purifies it to drinking water quality, then sends it back to the brewery to be reused as process water. The plant recovers and reuses 90% of its process water daily. “This has been a dream for us,” says the company’s brewing director.
The TWM plant produces 1800 cubic meters of pure water a day from the 2000 cubic meters of used process water it receives. The plant also produces biogas, which Carlsberg uses to heat its facilities.
Pantarein Water – a turnkey wastewater treatment plant provider based in Belgium – was tasked with providing the full treatment system. Grundfos was chosen to supply pumps and systems to move water and ensure precision dosing in the plant.
“Grundfos has a lot of know-how in pumps, of course,” says Pantarein’s project manager. “They helped us a lot during the offer phase to choose the right products for all the solutions we needed to offer. We did a lot of talking to get the most durable and efficient solutions – in consideration to both the energy consumption and sustainability. So that made a big difference for us.”
Carlsberg’s engineering consultancy partner NIRAS says Grundfos was chosen because “when it came to pumping and dosing, we wanted to make sure we got very reliable solutions. Because if one of these components is failing, the whole operation will fail. Secondly, we wanted to get solutions that allowed us to monitor and control the system, so we can constantly see how we are doing within the expected benchmarks. A lot of people learned that it’s not just a pump – there’s actually an intelligence in the pump.”
Carlsberg plans to roll out the learnings from its first TWM plant to build similar in its breweries in water-scarce areas.
