Biofilm developing in water systems, process lines and CIP systems can affect microbiological stability, taste, aroma and the shelf life of the final product.
At EHT, we provide professional sanitisation of water and process installations for the beverage and brewing industry, reducing biofilm, microorganisms and the risk of secondary process contamination.
Simply rinsing
with water
Only removes loose deposits from the installation, but does not solve the problem of biofilm, which can remain in pipelines, tanks and hard-to-reach places.
Sanitisation
EHT
Breaks down the biofilm structure, reduces environmental bacteria, wild yeasts and secondary contamination, supporting stable microbiology in the production process.
Every industry has different challenges. We tailor the solution
Production and process installations
Stable microbiology of lines, pipelines and process systems
Processing lines, pipelines, tanks and process fluid distribution systems require consistent microbiological control to reduce the risk of biofilm and secondary contamination.
CIP systems
More effective cleaning and hygiene control of installations
The process improves the effectiveness of CIP cleaning, reduces biofilm in hard-to-reach places and helps maintain the hygienic stability of the systems.
Beverage production
Microbiological safety and product shelf life
Controlling biofilm and environmental bacteria reduces the risk of changes in the taste, aroma and quality of beverages during production.
Brewing
Fermentation stability and consistent quality
Sanitisation helps control wild yeasts, Lactobacillus and other microorganisms that can affect fermentation and the shelf life of beer.
Vessels and process tanks
Reduced secondary contamination at key points of the installation
The process supports the elimination of biofilm, environmental bacteria and sources of infection in vessels, tanks and liquid distribution systems.
Production of ice and process water
Cleaner water systems used in production
Sanitisation supports microbiological control of process water, cooling systems, ice production and auxiliary installations.
What do you gain from our sanitisation?
Reduced biofilm in systems: sanitisation helps to remove biofilm from processing lines, pipelines, tanks and process fluid distribution systems.
More stable process microbiology: microbiological control of the systems reduces the risk of environmental bacteria, wild yeasts and process contamination developing.
Support for final product quality: microbiologically clean systems help to maintain consistent taste, aroma, shelf life and safety of beverages and brewing products.
More effective CIP systems: sanitisation supports cleaning processes, reduces biofilm in hard-to-reach places and helps to maintain the hygienic stability of the system.
Lower risk of secondary contamination: eliminating sources of contamination in the systems reduces the risk of microbiological problems recurring at later stages of production.
Fewer stoppages and complaints: more stable hygiene conditions help to reduce the risk of quality problems, production losses and unplanned plant downtime.
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.”
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

- 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

FAQ
Frequently asked questions
Why is system sanitisation important in beverage and beer production?
Biofilm can develop in water systems, process lines and CIP systems, promoting secondary contamination and affecting the microbiological stability of the process. In the beverage and brewing industry, this can affect the taste, aroma, shelf life and consistency of the product.
Is standard cleaning of the installation enough to remove biofilm?
Not always. Standard flushing or cleaning can remove loose deposits, but biofilm often persists inside pipelines, tanks, CIP systems and hard-to-reach parts of the installation. EHT sanitisation helps eliminate it and reduces the risk of recurring contamination.
Which parts of the installation can be sanitised?
The process can cover process lines, pipelines, vessels, process tanks, CIP systems, process water installations, cooling systems and systems used in ice production, among others.
What are the typical microbiological hazards in this industry?
The most common threats include process biofilm, wild yeasts, environmental bacteria, Lactobacillus, Pseudomonas and secondary contamination of installations.
What does the plant gain from EHT sanitisation?
Sanitisation supports more stable process microbiology, reduces biofilm, lowers the risk of secondary contamination, improves product safety, and helps maintain production consistency.
