CASE: Ultra-pure water with significant cost savings

The food industry places high demands on the quality of process water. At a large slaughterhouse in Jutland, Guldager has installed a series of“UniSoft® Hydrus”water softening systems to ensure clean, lime-free process water.

Soft water is essential for achieving optimal cleaning during the slaughtering process with minimal consumption. At the same time, it prevents limescale deposits on tiles and equipment, making daily cleaning easier.

The consumption of rinse water at the slaughterhouse was high, making it crucial that Guldager's high-efficiency Hydrus systems could reduce salt and regeneration water consumption compared to traditional softening systems.
