Biofilm developing in industrial water systems, cooling circuits, pipelines and tanks can reduce installation efficiency, destabilise processes and increase operating costs.

At EHT, we provide professional sanitisation of industrial water and process systems, reducing biofilm, environmental bacteria and the risk of secondary contamination in installations.

Simply rinsing
with water

Only removes loose deposits from the installation, but does not eliminate biofilm, which can remain in pipelines, tanks, heat exchangers and cooling systems.

Sanitisation
EHT

Breaks down the biofilm structure, limits the growth of microorganisms and helps restore stable operating conditions in industrial water systems.

Every industry has different challenges. We tailor the solution

Water recovery and recirculation 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 transfer and storage systems

Sanitisation helps reduce biofilm, bacteria and secondary contamination in tanks, pipelines and process systems.

Process  water
Greater stability of industrial processes

Microbiological control of water helps maintain production safety, limit process contamination and improve the consistency of system operation.

Heat exchangers and installation components
Protecting key points against biological deposits

Reducing biofilm in hard-to-reach places supports installation efficiency and lowers the risk of deteriorating system performance.

High-risk industrial installations
Modern microbiological control in demanding environments

EHT technology supports the sanitisation of production systems, industrial infrastructure and installations requiring a high level of operational stability.

What do you gain from our sanitisation?

Reduced biofilm in systems: sanitisation helps to eliminate biofilm from pipelines, tanks, cooling systems, heat exchangers and process systems.

More stable microbiology of water systems: controlling the growth of microorganisms reduces the risk of microbiological instability in process, technological and recirculated water.

Supporting continuous system operation: reducing biofilm and contamination helps to lower the risk of deteriorating performance and unplanned maintenance shutdowns.

Higher efficiency of process systems: microbiologically cleaner systems support the stable operation of cooling systems, water circuits and industrial processes.

Lower risk of secondary contamination: eliminating sources of contamination in the systems reduces recurring microbiological problems and improves process safety.

Lower operating and maintenance costs: stable system microbiology helps to reduce failures, additional cleaning, downtime and system maintenance costs.

Modern industrial microbiological control: EHT technology helps to maintain high operational stability in systems that require continuous hygiene 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 take water samples and carry out tests to determine the scale of the problem and select the right process parameters.

Selection of process parameters

We select the concentration and application conditions for chlorine dioxide (ClO₂). We take into account the specific characteristics of the system, flow rates and process requirements.

Carrying out sanitisation

We carry out the biofilm elimination process in the installation. Sanitisation is performed under the supervision of engineers, without the need for long production shutdowns.

Verification of effectiveness

We confirm the results of the process with microbiological testing. We take swabs and carry out ATP tests to confirm the elimination of biofilm and the effectiveness of sanitisation.

CASE STUDY

Sanitisation in practice

Restoring the microbiological safety of a domestic hot water system
Water hygiene in laying hen production
Water hygiene on a pig farm
Water hygiene in pig fattening — large-scale commercial farm

Facility

Public primary school, Opole Voivodeship.

Challenge

A microbiological problem was identified in the domestic hot water system which, despite
previous remedial attempts, remained unresolved. The situation called for action that was
fast, precise and well controlled.

Scope of work

EHT Poland assessed the technical and microbiological condition of the installation, prepared and implemented a disinfection procedure, and introduced the disinfectant solution into the system, verifying that it reached all draw-off points, maintaining the correct contact time and finally flushing the installation.

Results

  • Effective elimination of the microbiological problem — confirmed by water testing after the service
  • Test result: no Legionella bacteria detected (0 CFU)
  • Solving a problem that previous methods had failed to resolve
  • Work carried out in an orderly, effective and safe manner for a public facility

Client testimonial

“The company demonstrated practical knowledge, responsibility and effectiveness in a situation requiring fast and well-controlled action.”

Head Teacher, Public Primary School, Strzelce Opolskie

Farm

Laying hen farm, Masovian Voivodeship. Cooperation since April 2025.

Challenge

Before implementation, the water system required frequent operational interventions and the microbiological condition of the water varied over the production cycle. Intestinal problems in the flock and unpredictable drinker performance reduced production stability.

Implementation

EHT Poland provides ongoing care of the farm’s water system. The cooperation includes regular monitoring of water quality, maintaining the hygiene of the drinking-water lines and ongoing technical support. Visits are carried out systematically, measurements are taken regularly, and recommendations are communicated to staff in a clear, practical way.

Results

  • Lasting removal of biofilm from the drinking-water system
  •  Stable water microbiology along the entire length of the line
  • Even drinker performance and no clogging
  • Fewer intestinal problems in the flock
  • More consistent production results
  • More predictable work for farm staff

Client testimonial

“The cooperation is conducted reliably and competently, and ongoing technical supervision has made it possible to stabilise the operation of the water system and improve production safety.”

Owner of a laying hen farm, Masovian Voivodeship

Farm

Pig production in a closed-cycle system — 100 sows, approx. 1,100 fattening pigs per year.

Challenge

The drinking-water system needed improvement — the presence of biofilm and unsatisfactory microbiological water parameters were causing health problems in the animals: gastrointestinal disorders, mortality during fattening and a longer fattening period.

Implementation

EHT Poland assessed water quality and inspected the drinking-water system, then implemented continuous sanitisation using ProOxine® technology (chlorine dioxide). The process included several service visits with concentration measurements, system performance assessments and microbiological water testing.

Results

  • Biofilm eliminated throughout the drinking-water system
  • Improved microbiological water parameters — confirmed by testing
  • Increased feed intake — first in sows, then in fatteners
  • Significantly shorter fattening period
  • No mortality caused by gastrointestinal problems
  • Easier, consistent control of drinking-water system cleanliness

Client testimonial

“The greatest value was the improved control over water hygiene and the practical technical support. The solution was implemented under real production conditions, taking into account the specifics of the farm and the production cycle.”

Challenge

The farm needed to improve its water hygiene standards and the quality control of its drinking-water system. The aim was to reduce mortality, eliminate biofilm and anaerobic bacteria, and stabilise production throughout the cycle.

Implementation

EHT Poland audited the water system, implemented a water hygiene system based on ProOxine® technology and provided ongoing supervision of water quality parameters and drinking-water line cleanliness throughout the production cycle.

Results

  • Lower mortality compared with the previous production cycle
  • Very good microbiological water test results — no abnormalities
  • No biofilm in the drinking-water lines — confirmed by a technical assessment of the installation
  • High and stable ORP level of the water throughout the cycle
  • Elimination of anaerobic bacteria in the water system
  • No clogging of nipple drinkers
  • Stable production throughout the cycle
  • No need to clean and disinfect the drinking-water lines thanks to continuous system hygiene

FAQ

Frequently asked questions

Where does biofilm most commonly form in industrial systems?

Biofilm can develop in pipelines, tanks, cooling circuits, heat exchangers, process systems, and water recovery and recirculation systems.

It can impair the installation’s operating parameters, reduce system efficiency, increase the risk of contamination and raise operating and maintenance costs.

Yes. Sanitisation helps reduce biofilm and microorganisms in cooling systems, which can improve operational stability and support heat transfer efficiency.

The most common are biofilm in the installation, environmental bacteria, Legionella, Pseudomonas, secondary contamination of installations and microbiological instability of water processes.

The process helps reduce biofilm, stabilise the microbiology of water systems, lower the risk of secondary contamination and support the continuous operation of the installation.
