Thermal efficiency: -15% energy consumption and plant protection

The company needed to eliminate limescale formation in the feed water supplying the steam boilers, which are essential for pasteurization and sterilization, while ensuring 24/7 operational continuity.

The technical challenges

High Water Hardness

High concentrations of calcium and magnesium were causing continuous scale build-up in the steam lines.

Reduced Energy Efficiency

Limescale deposits acted as thermal insulation, significantly increasing boiler energy consumption.

Frequent Downtime

Continuous extraordinary maintenance was required on heat exchangers and clogged piping.

Steam Quality

High-quality steam was essential for milk pasteurization processes and CIP (Clean-In-Place) cleaning.

The solution: tailor-made engineering

We installed an advanced water softening system to ensure a continuous supply of high-quality process water:

PRX-SOFT 30000 DUPLEX Water Softener

Dual-column system with a flow rate of 30 m³/h, designed for continuous alternating operation.

High-Capacity Cation Exchange Resins

For complete hardness removal and full protection of the boilers.

Volumetric Automation


Valves controlled by an industrial PLC for precise regeneration cycles based on actual water consumption.

Brine Optimization

Intelligent regeneration system designed to minimize salt consumption and rinse water usage.

Technology

Duplex ion-exchange water softening

Mains Water

Hard water, rich in calcium and magnesium, is conveyed to the treatment system.

Ion Exchange

The cation exchange resins remove hardness-causing minerals, delivering softened water to the boiler plant.

Automatic Regeneration
While one column is in operation, the other is automatically regenerated with brine, ensuring a continuous steam supply.

Clean Steam

The softened water feeds the boilers without causing scale deposits, optimizing heat transfer.

Results and economic impact

-15% energy consumption

Achieved by restoring maximum heat exchange efficiency in the boilers.

-30% maintenance costs

Elimination of chemical descaling operations and piping replacement.

24/7 reliability

Full continuity of pasteurization and cheese production cycles without technical downtime.

Asset protection

Significant increase in the service life of the boilers and the entire steam distribution network.
