Sanitisation of water systems in livestock production
We restore the microbiological purity of water systems
We remove biofilm and restore the microbiological safety of installations — regardless of the sector or the scale of the system.

Biofilm developing on surfaces, processing lines and in hard-to-reach areas can lead to recurring contamination, quality problems and costly production losses.
At EHT, we carry out professional disinfection of production surfaces and spaces, effectively eliminating biofilm, reducing the risk of cross-contamination and helping maintain the highest standards of production hygiene.
Simply rinsing
with water
Removes loose deposits, leaves most of the biofilm in place and has only a short-term effect.
Sanitisation
EHT
Breaks down the biofilm structure, removes sources of contamination and restores stable operating conditions in the installation.
Every industry has different challenges. We tailor the solution
Drinking-water systems
Clean drinking-water lines and stable microbiological water quality
Sanitisation reduces biofilm in drinking-water systems, supporting the microbiological safety of the installation and a constant supply of cleaner water.
Water lines and process installations
Reduced risk of secondary contamination in the installation
The process helps keep water systems free-flowing, limits the growth of microorganisms and helps stabilise water-related technological processes.
Tanks and water storage
Microbiological control of standing water
Sanitisation helps limit the growth of biofilm, bacteria, fungi and other microorganisms that can multiply in tanks and water storage points.
Poultry farms
Support for biosecurity and flock health
Microbiological control of water reduces the risk of pathogen spread, supporting the hygiene of drinking systems and the stability of poultry production.
Pig farming
Stable microbiology of water systems
EHT technology helps reduce biofilm and secondary contamination in water systems, which can affect production safety and farming conditions.
Dairy and beef cattle
Safer drinking-water systems and infrastructure hygiene
Sanitisation supports microbiological water quality control, animal welfare and a cleaner water infrastructure in livestock facilities.
What do you gain from our sanitisation?
Faster and more effective sanitisation: the high reactivity of chlorine dioxide shortens the time needed to eliminate biofilm.
Longer system service life: eliminating biofilm reduces the risk of under-deposit corrosion and improves the system's operating conditions.
Microbiological safety and compliance with standards (ESG): we use chlorine dioxide (ClO₂)-based solutions that place no burden on the system or the environment.
Full control and reporting: you receive microbiological test results before and after the process, together with confirmation of its effectiveness.
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.”

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.”
Farm
Pig fattening farm – approx. 2,000 fattening pigs per 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
- Better working conditions for farm staff
