Biocides for Industrial Water Circuits: Effective Control of Microbial Growth

Even low levels of microbial contamination can affect process reliability in industrial water circuits. Bacteria, fungi and algae can multiply rapidly in stagnant or recirculating media. Without suitable control measures, this can contribute to quality issues, increased maintenance requirements and equipment problems. Potential consequences include:

  • Unpleasant odors and reduced performance of the process fluid
  • Biofilm formation and phase separation
  • The release of potentially harmful metabolic by-products or the presence of Legionella

Biocides are active substances used to control or eliminate harmful organisms in technical water systems. For more than 30 years, RHOBA-Chemie has been developing chemical solutions for industrial applications. Our biocidal products are designed for the specific requirements of technical water circuits. They help control microbial growth, support the protection of equipment components and help operators meet applicable regulatory requirements during operation.

Broad-Spectrum Biocides for Cooling Water and Process Systems

Whether in open cooling towers, closed cooling circuits or water-mixed metalworking fluids, broad-spectrum biocides can support microbiological stability across a wide range of process media. Depending on the active substance and application, they act against bacteria, fungi and algae and can help control microbial growth at an early stage, reducing the conditions that contribute to persistent biofilm formation.

Applications of Our Biocides

Cooling Water Hygiene

Biocides help control the growth of algae, bacteria, yeasts and fungi in cooling systems. This can help reduce deposits on heat exchangers and support consistent heat transfer.

Process and Rinse Water

In emulsions, rinse baths and process fluids, biocides can help maintain microbiological stability over extended service periods and reduce unwanted changes in the process media.

Industrial Parts Cleaning and Surface Treatment

In cleaning and final-rinse processes, biocides can help reduce the risk of microbial contamination being carried over and support consistent process conditions.

Challenges in Equipment Operation – Preventing Biofilms at an Early Stage

Biofilms form when microorganisms attach to pipes, tanks and other equipment components. As the biofilm layer increases, flow conditions and heat transfer can be affected. Over time, restrictions or even blockages may develop. This can result in more frequent maintenance, unplanned downtime and increased operating costs.

In addition to the technical requirements, companies must consider applicable regulatory requirements for the use and labeling of biocidal process media. Formulation and dosage should therefore be selected so that the required level of protection is achieved while applicable labeling and regulatory requirements are taken into account.

Safe Handling of Biocides: Responsible Use in Industry

Because biocides are specifically designed to control or inhibit biological processes, their use requires appropriate expertise and precise dosing. Unnecessarily high doses can increase environmental exposure and may affect non-target organisms.

Together with you, we develop a dosing concept that supports the required level of protection while taking environmental and regulatory requirements into account. At our training center, we provide your employees with practical training on the safe, compliant and responsible handling of our biocides.

System Hygiene with a Structured Approach: From Laboratory Analysis to Optimized Dosing

Stable water quality starts with a sound analysis. Our experts can therefore support you from the initial water sample through to long-term monitoring of your systems.

Measurement and Sampling

We take water samples directly from your circuits and carry out laboratory analyses to determine the level of microbial contamination and other relevant process parameters.

Individual Consulting

Based on the laboratory results, we recommend a suitable biocidal product and develop a dosing concept tailored to your processes, including dosing quantities and application intervals.

Monitoring and Fluid Management

If required, we can continuously monitor your process media as part of our fluid management services. This helps detect changes at an early stage and allows appropriate measures to be initiated in good time.
