In-house water supply for dairy cooperative

Mlekpol Dairy Cooperative is one of the largest manufacturers of milk and dairy products in Europe. They have 13 modern and highly specialized processing plants located in Poland.

In the city of Mrągowo, in the northeastern part of Poland, the second largest of Mlekpol’s dairy production plants is placed. In 2022, their new water treatment solution with a capacity of 230 m³/h was put into operation. The existing water treatment plant was insufficient to supply the amount of process water needed for a new milk powder plant with a planned capacity of three million liters of milk and whey per day.

The water source is groundwater, containing several natural salts and organic substances, particles, and gasses. The water treatment steps are aeration and pressure filtration divided into two steps for iron removal and manganese removal. The treated water goes to two external storage tanks, each with a capacity of 400 m³. The water is then distributed to the different production zones by two booster systems based on Grundfos CR pumps.

The solution also includes a softening unit for the process water, which is used, among other things, for centrifugal pumps and as pre-treatment in the boiler room.
