Cleaning pipes, tanks and vehicles
We remove PFAS from pipes, tanks and vehicles
Professional cleaning
Fluorine-containing fire-fighting foam has been used extensively at airports, fire brigades, industrial companies, logistics companies and Defence. The fire-resistant foam is stored in tanks. Through testing and use of the fire-fighting systems, fire-fighting foam has also entered pipes.
When using and testing fire extinguishing systems, PFAS residues may remain in:
-
tanks
-
pipes
-
pump and mixing systems
-
appendages and connections
-
other components containing fluorinated foam concentrate
PFAS are known to penetrate deep into cracks and voids of materials, making them difficult to remove. The ability of our cleaning method to infiltrate deep into porous surfaces ensures that it can effectively target and eliminate PFAS, even in hard-to-reach areas.
Effective cleaning of fire protection systems prevents
PFAS residues end up in the environment via the new foam.

year warranty
We offer a one-year guarantee on “rebound”. This means that after cleaning, we determine the PFAS level by means of an analysis by an accredited laboratory. After one year, the PFAS level must still be below the legal standard.
The cleaning process
The main points
The cleaning process to remove PFAS (per- and polyfluoroalkyl substances) from pipes involves several steps and techniques. This process can vary depending on the specific situation, the level of PFAS contamination and the technologies used. It is important to work together with the customer and the experts in water management and environmental legislation to create an effective cleaning plan.
1. Identification and monitoring
-
Detection: before the cleaning process begins, it is essential to identify the PFAS value that is present. This can be done by means of laboratory analyses.
-
Monitoring: continuous monitoring of PFAS levels in the system and water during the cleaning process is necessary to assess the effectiveness of the cleaning.
2. Preparation
-
Shutting down the system: the thing to be cleaned (tank, pipework or vehicle) must be temporarily shut down to allow the cleaning to be carried out safely.
-
Safety precautions: personnel must wear protective equipment and measures must be taken to prevent contamination.
3. Cleaning techniques
-
Pre-program: the system is filled and flushed with a liquid that ensures that the foam does not foam too much.
-
Cleaning: the system is filled with Sani A. This cleans the system deep into the pores.
-
Rinsing: Sani A is rinsed out of the system and collected. The system is then rinsed and cleaned with hot water under high pressure.
4. Waste disposal
-
Waste management: waste generated during the cleaning process (e.g. saturated filters or chemical by-products) must be disposed of safely in accordance with applicable legislation.
5. Aftercare and monitoring
-
Repeat testing: after cleaning, re-testing must be performed to confirm that PFAS levels are below regulatory standards.
-
Long-term monitoring: it is important to set up a monitoring program to prevent any future PFAS contamination.
6. Documentation and reporting
-
Reporting: document the entire process, including techniques used, test results, and any problems encountered.
-
Communication: inform stakeholders and the public about the results and actions taken.
Important points to note
Collaboration with client, competent authority and water manager to determine permits and limit values
Determining what needs to be cleaned
Preliminary performance of a Health and Safety Risk Assessment (HSRA) and Task Risk Analysis (TRA)
Take a sample in advance and take three samples at different times after cleaning
Correctly dispose of and process waste materials
