Biofilm developing in water installations, technological systems, and auxiliary units can encourage secondary contamination, the growth of environmental bacteria, and microbiological instability of processes.
At W EHT, we provide professional sanitisation of water systems for the medical and pharmaceutical industries, supporting microbiology control, biofilm reduction, and the hygienic stability of installations.
Simply rinsing
with water
It only removes loose contaminants, but does not eliminate biofilm, which can persist in pipelines, tanks, process circuits, and utility installations.
Sanitisation

Biofilm limitation in key installation components
The process helps to limit the development of biofilm, Legionella, Pseudomonas, and environmental bacteria at points susceptible to secondary contamination.
Environments with high hygiene requirements
Modern control of microbiology in water processes
EHT technology supports installations requiring particular hygienic stability, constant microbiological control, and reduced contamination risk.
What are the benefits of our sanitisation service?
Biofilm limitation in installations: Sanitisation helps to limit biofilm in pipelines, tanks, process circuits, and utility and process water installations.
Better microbiology control for water systems: The process supports the maintenance of stable water microbiological quality and limits the growth of environmental bacteria.
Reduced risk of secondary contamination: Eliminating sources of contamination in installations helps to reduce the recurrence of microbiological problems in utility and process systems.
Greater hygienic stability of the installation: Biofilm control supports the maintenance of high hygiene levels in medical, pharmaceutical, and technical environments.
Infrastructure security support Sanitisation of water installations helps to limit risks associated with environmental bacteria, Legionella, Pseudomonas, and unstable microbiology.
More stable technological processes: More microbiologically clean water systems support process safety, quality compliance and the reduction of technological contamination risks.
Modern microbiological control EHT technology allows for more effective management of water system hygiene in facilities with high sanitary and quality requirements.
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 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.
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

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
- Greater predictability of farm staff work
Customer feedback
„The collaboration is being carried out in a reliable and professional manner, and ongoing technical supervision will help to stabilise the operation of the water system and improve production safety.”
Farm
Pig production in a closed-cycle system — 100 sows, approx. 1,100 fattening pigs per year.
Challenge
The watering system needed improving — the presence of biofilm and unsatisfactory microbiological parameters of the water were leading to health problems in the animals: gastrointestinal disorders, weight loss during fattening and prolonged fattening periods.
Implementation
EHT Poland conducted a water quality assessment and drinking installation check, and subsequently implemented continuous sanitisation using ProOxine® technology (chlorine dioxide). The process involved multiple service visits with concentration measurements, system performance evaluation, and microbiological water testing.
Effects
- Biofilm elimination throughout the drinking water installation
- Improvement in the microbiological parameters of water — confirmed by tests
- Increase in feed intake - first in sows, then in fattening pigs
- Significant reduction in the fattening period
- Reduction in falls caused by gastrointestinal problems
- Easier, more stable control of the drinking system's cleanliness
Customer feedback
„The greatest value was the improved control over water hygiene and practical technical support. The solution was implemented in real production conditions, taking into account the specific characteristics of the farm and the production cycle.”
Farm
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
- No clogging of the nipple drinkers
- Stabilising the production process during the cycle
- No need to clean and disinfect the watering lines thanks to the system’s constant hygiene standards
- Improving the working comfort of farm staff
