Optimization of Cooling Water Systems in a Production Environment

• The increased hardness of the makeup water limited the maximum achievable concentration in the cooling towers.
• Excessive concentration in several cooling towers increased the risk of scale buildup.
• Widely varying operating conditions made it difficult to maintain consistent water quality.
• The first signs of microbiological activity were detected through shifts in the nitrogen balance.
• The concentration of corrosion inhibitors in the closed cooling circuit was below the desired level.

• The system needed to be continuously protected against corrosion, deposits, and microbiological contamination without affecting production.

In addition, the customer wanted to optimize water consumption while ensuring the reliable operation of the cooling systems.

• The optimizations implemented resulted in significant improvements in the cooling systems:
• Water quality remained under control in all sampled systems.
• Microbiological contamination was successfully reduced to acceptable levels.
• Metal concentrations remained stable, indicating effective corrosion control.

• The risk of new calcium deposits was significantly reduced.
• A uniform distribution of the treatment products was confirmed within the closed cooling circuits.
• Corrosion protection improved compared to previous measurements.
• The water treatment parameters evolved toward optimal operating conditions.
• A solid foundation was laid for further efficiency improvements and a longer service life for the facilities
