Biofilm developing in water installations, CIP systems, tanks, and processing lines can lead to secondary contamination, unstable microbiology, and reduced shelf-life of food products.
At W EHT, we provide professional sanitisation of water and technological installations for the food processing industry, reducing biofilm, environmental bacteria, and the risk of process contamination.
Simply rinsing
with water
It only removes loose contaminants from the installation but does not eliminate biofilm, which can remain in pipelines, CIP systems, tanks, and heat exchangers.
Sanitisation
EHT
It breaks down biofilm structure, limits microorganism growth, and supports stable hygiene in installations used in food production.
Every industry faces different challenges. We tailor our solutions accordingly.
Process water
Safer water used in production processes
Sanitisation supports the control of process water microbiology, reducing the risk of contamination and helping to maintain the stability of food production processes.
CIP Systems
More effective cleaning and a high level of installation hygiene
The process limits biofilm in CIP systems, supports washing efficiency and helps maintain the microbiological cleanliness of technological installations.
Ice production and brine
Microbiological control of cooling systems
Sanitation supports the hygiene of refrigeration, ice production and brine systems, reducing the risk of secondary contamination of food products.
Tanks and process installations
Reduced risk of contamination at key production points
The process helps to limit biofilm, environmental bacteria and microorganisms developing in tanks, pipelines and production facilities.
Meat processing plants and protein processing
Production safety and product durability support
The microbiological control of water installations reduces the risk of secondary contamination, which can affect food safety and the quality of protein products.
Dairies and dairy production
Stable hygiene of dairy installations
Sanitisation helps to limit biofilm and unstable microbiology, which can affect process safety, product quality, and production continuity.
What are the benefits of our sanitisation service?
Biofilm elimination in installations: Sanitisation helps remove biofilm from pipes, CIP systems, tanks, heat exchangers, and process equipment.
More stable plant microbiology: Inhibiting the growth of microorganisms helps maintain repeatable hygienic conditions in food production processes.
Reduced risk of secondary contamination: The elimination of contamination sources in installations limits the recurrence of microbiological problems and the risk of product contamination.
Food safety support: Microbiological control helps to limit threats such as Listeria, Salmonella, E. coli, Pseudomonas, and environmental bacteria.
Greater stability of production processes: Microbiologically cleaner installations support production continuity, limit the risk of stoppages and quality problems.
Longer product shelf life: Preventing secondary contamination and unstable microbiology helps to protect the quality and shelf-life of food products.
Reduced risk of complaints and losses: Stable plant hygiene reduces the risk of quality issues, which can lead to complaints, recalls, or production losses.
Modern Industrial Hygiene Control The EHT technology supports the maintenance of a high level of hygiene in water, CIP, cooling, and process installations.
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

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

„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
