Biofilm developing in industrial water systems, cooling systems, pipelines, and tanks can reduce plant efficiency, destabilise processes, and increase operating costs.
At W EHT, we carry out professional sanitisation of industrial water and process systems, reducing biofilm, environmental bacteria, and the risk of secondary contamination in installations.
Simply rinsing
with water
It only removes loose contaminants from the installation, but does not eliminate biofilm, which can remain in pipelines, tanks, heat exchangers and cooling systems.
Sanitisation
EHT
It breaks down biofilm structure, limits microbial development and helps restore stable operating conditions for industrial water systems.
Every industry faces different challenges. We tailor our solutions accordingly.
Water recovery and recycling systems
Stable water microbiology after recovery processes
Sanitisation supports the microbiological control of water in closed systems, reducing the risk of secondary contamination and water quality instability.
Cooling systems and cooling towers
Biofilm reduction and improved heat exchange efficiency
The process helps to limit the growth of biofilm and environmental bacteria, which can affect the safety and efficiency of cooling systems.
Tanks and process pipelines
Microbiologically cleaner distribution and storage systems
Sanitisation helps to reduce biofilm, bacteria and secondary contamination in tanks, pipes and technological systems.
Process and technological water
Greater stability of industrial processes
Monitoring the microbiology of water helps to maintain production safety, minimise process contamination and improve the reliability of the systems.
Heat exchangers and installation components
Protection of key points from biological deposits
Reducing biofilm in hard-to-reach areas helps to maintain the efficiency of the installation and reduces the risk of a deterioration in the system’s performance.
High-risk industrial installations
Modern microbiology control in demanding environments
EHT technology supports the sanitisation of production systems, industrial infrastructure and installations requiring a high level of operational stability.
What are the benefits of our sanitisation service?
Biofilm limitation in installations: Sanitisation helps to eliminate biofilm from pipelines, tanks, cooling systems, heat exchangers, and processing systems.
More stable microbiology of aquatic systems Control of microbial development limits the risk of microbiological instability in process, technological, and recirculated water.
Business continuity support for installations Reducing biofilm and contamination helps to minimise the risk of a deterioration in operating performance and unplanned maintenance downtime.
Greater efficiency of technological systems Microbiologically cleaner systems help to ensure the stable operation of cooling systems, water circuits and industrial processes.
Reduced risk of secondary contamination: Eliminating sources of contamination in installations limits the recurrence of microbiological problems and improves process safety.
Lower operating and maintenance costs: Stable microbiology in installations helps to reduce failures, additional cleaning, downtime, and system maintenance costs.
Modern industrial microbiology control: EHT technology supports the maintenance of high operational stability in installations requiring constant hygienic supervision.
The sanitisation process, step by step
Analysis of the installation and contamination
We identify the presence of biofilm and the level of microbiological contamination. We collect water samples and carry out tests to determine the scale of the problem and select appropriate process parameters.
Selection of process parameters
We are selecting the concentration and application conditions for chlorine dioxide (ClO₂). We take into account the specifics of the installation, flow rates, and technological requirements.
Sanitisation implementation
We are carrying out a biofilm elimination process in the installation. Sanitisation is performed under the supervision of engineers, without the need for long production downtimes.
Effectiveness verification
We confirm the results of the process with microbiological testing. We perform swabs and ATP tests to confirm the elimination of biofilm and the effectiveness of sanitisation.
CASE STUDY
Sanitisation in practice
Restoring the microbiological safety of domestic hot water installations
Water sanitisation in laying hen production
Water hygiene in pig farming
Water sanitisation in pig fattening - large-scale farm
Object
State primary school, Opole Voivodeship.
Challenge
In the domestic hot water installation, a microbiological problem was identified, which despite
the earlier remedial attempts remained unresolved. The situation required action
quick, precise, and well-controlled.
Scope of work
EHT Poland conducted an assessment of the technical and microbiological status of the installation, prepared and implemented a disinfection procedure, introduced the disinfectant solution into the installation with control of the preparation's reach to all sampling points, maintained the correct contact time, and finally flushed the installation.
Effects
- Effective elimination of microbiological contamination – confirmed by post-service water testing
- Test result: no presence of Legionella bacteria (0 cfu)
- A solution to a problem that remained unsolved by previous methods.
- Work carried out in an organised, effective and safe manner for a public utility facility
Customer feedback
„The company demonstrated practical knowledge, responsibility, and effectiveness in a situation requiring swift and well-controlled actions.”
Headteacher, Public Primary School, Strzelce Opolskie
Farm
Laying hen farm, Masovian Voivodeship. Cooperation from April 2025.
Challenge
Before implementation, the water installation required frequent operational interventions, and the microbial quality of the water varied during the production cycle. Intestinal problems in the herd and unpredictable operation of the drinkers reduced production stability.
Implementation
EHT Poland provides ongoing care for the farm's water installation. The cooperation includes regular monitoring of water quality, maintaining the hygiene of the drinking lines, and ongoing technical support. Visits are carried out systematically, measurements are taken regularly, and recommendations are communicated in a clear and practical way for the staff.
Effects
- Permanent removal of biofilm from drinking water systems
- Stable water microbiology throughout the entire length of the line
- Uniform operation of drinkers and no clogging
- Reducing intestinal problems in the flock
- Improving the repeatability of production results

Pig fattening farm – approx. 2,000 fattening pigs per cycle.
Challenge
The farm required an improvement in water hygiene standards and quality control of the drinking-water installation. The aim was to reduce mortality, eliminate biofilm and anaerobic bacteria, and stabilise production throughout the cycle.
Implementation
EHT Poland conducted an audit of the water installation, implemented a water hygiene system based on ProOxine® technology, and provided constant supervision over water quality parameters and the cleanliness of the drinking lines throughout the entire production cycle.
Effects
- Decrease in falls compared to the previous production cycle
- Very good microbiological results for the water - no abnormalities
- Absence of biofilm in drinking lines – confirmed by technical installation assessment
- High and stable ORP level of the water throughout the cycle
- Elimination of anaerobic bacteria in the water system
