Biofilm developing in water systems, CIP systems, tanks and processing lines can lead to secondary contamination, unstable microbiology and a shorter shelf life of food products.
At EHT, we provide professional sanitisation of water and process installations for food processing plants, reducing biofilm, environmental bacteria and the risk of process contamination.
Simply rinsing
with water
Only removes loose deposits from the installation, but does not eliminate biofilm, which can remain in pipelines, CIP systems, tanks and heat exchangers.
Sanitisation
EHT
Breaks down the biofilm structure, limits the growth of microorganisms and supports stable hygiene in installations used in food production.
Every industry has different challenges. We tailor the solution
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 reduces biofilm in CIP systems, improves cleaning effectiveness and helps maintain the microbiological cleanliness of process installations.
Ice and brine production
Microbiological control of cooling systems
Sanitisation supports the hygiene of refrigeration installations, 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 limit biofilm, environmental bacteria and microorganisms growing in tanks, pipelines and production installations.
Meat plants and protein processing
Supporting production safety and product shelf life
Microbiological control of water systems 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 reduce biofilm and unstable microbiology, which can affect process safety, product quality and production continuity.
What do you gain from our sanitisation?
Biofilm elimination in systems: sanitisation helps to remove biofilm from pipelines, CIP systems, tanks, heat exchangers and process installations.
More stable system microbiology: limiting the growth of microorganisms helps to maintain consistent hygiene conditions in food production processes.
Lower risk of secondary contamination: eliminating sources of contamination in the systems reduces recurring microbiological problems and the risk of product contamination.
Supporting food safety: microbiological control helps to reduce hazards such as Listeria, Salmonella, E. coli, Pseudomonas and environmental bacteria.
Greater stability of production processes: microbiologically cleaner systems support production continuity and reduce the risk of stoppages and quality problems.
Longer product shelf life: reducing secondary contamination and unstable microbiology helps to protect the quality and shelf life of food products.
Lower risk of complaints and losses: consistent system hygiene reduces the risk of quality problems that could lead to complaints, recalls or production losses.
Modern process hygiene control: EHT technology helps to maintain a high standard of hygiene in water, CIP, refrigeration and process systems.
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), taking into account the specifics of the installation, flow rates and technological 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
- 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
