Water-cleaning solution

Within the production process, water needs to be separated out from the milk. This residual ‘cow water’ as it is colloquially known, includes the nitrogenous compound urea, that some treatment plants struggle to deal with. At Arla, it needed to be sent off-site to be treated, which was an expensive process. Grundfos introduced Arla to its BioBooster, one of its next-generation solutions.

These stand-alone units clean wastewater in a biological process, that through its ultrafiltration membranes, eliminates bacteria at its source by removing organic and bacterial contamination. Treated water complies with strict discharge limits and achieves all necessary water reuse standards.  

The outcome has been that at this one Arla site alone, 450m3 of water can be cleaned daily. This can be reused in a suitable process or despatched into a local water course.

At the recent Global Water Summit this Arla/Grundfos project received the Industrial Water Project of the Year award.
