CASE: Completely clean water with significant savings

The food industry has high demands on the quality of process water. At a major slaughterhouse in Jutland, Guldager has installed a series of "UniSoft® Hydrus" softeners to ensure clean and lime-free process water.

The soft water is essential to achieve optimal cleaning in the slaughtering process with the least possible consumption. At the same time, there is no build-up of lime on tiles and equipment, making daily cleaning easier.

The consumption of water for rinsing at the slaughterhouse was high, and it was therefore crucial that Guldager's highly efficient Hydrus system could reduce the consumption of salt and water for regeneration compared to traditional softening systems.
