The essential
Water-saving process
Maximum safety for operators
Taking up and eliminating the most PFAS-concentrated liquids
In situ treatment of cleaning effluents
Chemical cleaning
Transition to PFAS-free firefighting foams
Most of the foam additives used in fire-fighting systems contain PFASs, whose use will be phased out by 2035. Our Solarca subsidiary empties your tanks, cleans your installations and treats all your fluorinated waste.
Get in touch with an expert
Are you looking to decontaminate your fixed installations that have contained fluorinated emulsifiers, as part of the regulatory transition to PFAS-free emulsifiers?
A comprehensive service
For these delicate operations, our teams accompany you from project engineering and the design of the intervention to the supply of equipment (pumps, temporary piping, retention material, PPE...) and the disposal of waste to approved treatment channels.
An effective partnership
For the decontamination work itself, we work in partnership with the company Cornelsen, a key player on the German market. Cornelsen has carried out over 300 interventions in recent years to decontaminate the fixed and mobile tanks of fire brigades, thanks to its 2019 patented technology: PerfluorAd®. This liquid reagent allows precipitation and removal of PFAS compounds, guaranteeing optimized decontamination.
A supervised intervention
No surprises: in advance of the intervention we provide you with all the documents
- technical
intervention work procedures, operational planning - regulatory
Prevention plan, risk analysis, Safety Data Sheets (SDS) for chemicals used.
And, of course, a detailed report at the end of the intervention.
Transitioning your emulsifiers, step by step
1. Engineering
From your documents and technical site visits we design the successive phases of the Decontamination Operating Procedure:
- work procedures (assembly/disassembly, filling, circulation, rinsing and effluent storage).
- equipment plans and their prior preparation (removal of clappers, proportioners that cannot be rinsed, etc.
- cleaning sequences: pipes, cannons, tanks, pumps etc.
- energy, water, air requirements, temporary storage (IBC), storage area etc.
- Safety Data Sheets (SDS) and quantities of chemicals required.
- analytical control procedures for cleaning phases.
- layout plan for temporary equipment on site.
- pre- and post-work inspection procedures.
We also draw up the risk analysis corresponding to the various phases of work.

2. Draining fluorinated emulsifiers
The emulsifiers are pumped into IBC-type containers for storage and then transported to an authorized treatment facility.

3. Cleaning fluorinated emulsifier residues
The removal of concentrated foam residues is carried out using rotary heads and/or medium-pressure jets from the tank manholes.
A method that limits interventions inside the tanks.
The feed and return lines are also "flushed". These first rinse waters are also stored in IBCs for disposal in one of our external treatment centers

4. Chemical decontamination of tanks and networks
Once the emulsifier residues have been removed, the tanks and all feed and return lines are partially filled with a decontaminant solution. This solution is recirculated, reheated and drained. One or more rinses are then performed with water.
These sequences of circulating the decontamination solution and then rinsing with water can be repeated until the analyses provide satisfactory results.

5. Rinse water management
All rinsing water is pumped, treated by batch and transferred to temporary tanks until an approved laboratory certifies that the treated water complies with discharge criteria.

6. Decontamination validation
After analysis of the last rinsing water, decontamination is validated by an external laboratory.
7. Off-site disposal of solid and liquid waste
All fluorinated emulsifiers stored in IBCs, as well as highly concentrated rinse water, are then collected and transported to the Group's approved treatment centers. The same procedure is followed for all soiled solid waste (PPE, rags, absorbents, etc.).
