At Dafo Fomtec in Helsingborg, all wash water from firefighting foam production was previously sent for incineration — a costly and environmentally demanding process. Helios Innovations installed an on-site treatment plant that enables water reuse directly in production and reduces waste volume by 90%.
Helsingborg, Sweden
Chemical & Pharmaceutical Wash water from foam production contained hazardous chemicals that could not be handled with conventional methods and required destruction. Dafo Fomtec needed a safe and efficient solution that minimises environmental impact.
An on-site treatment plant installed during spring and summer 2025, using low-temperature evaporation at atmospheric pressure to purify the water. Automated systems and continuous monitoring ensure stable purification performance and high operational reliability.

CO₂ saved annually (Scope 3)
Only 10% of the wash water now requires destruction, compared to 100% previously — a tenfold reduction in hazardous waste sent for incineration.
Water recirculation saves approximately 135,000 litres of freshwater annually and reduces CO₂ emissions by around 16 tonnes in Scope 3.
Automated alarm systems and continuous monitoring ensure stability and minimal maintenance throughout operation.
The installation demonstrates how firefighting foam manufacturers can combine sustainability with resource efficiency — an important step towards more sustainable handling of contaminated wash water from foam production.
The plant serves as a model for similar industries across Europe to adopt the same purification technology, reducing both costs and environmental impact.
