PFAS mineralization

PFAS degradation in landfill leachate

PFAS (Poly- and Per-Fluoro Alkyl Substances) represent a class of synthetic chemical compounds categorized as Emerging Contaminants (ECs). These substances are widely used across various industrial sectors, but despite their exceptional waterproofing and flame-retardant properties, PFAS have drawn the attention of the scientific community due to their negative impact on the environment and human health.

The widespread presence of PFAS in drinking and wastewater demands advanced removal solutions. Traditional treatment methods face challenges in breaking the C-F bond due to fluorine's high electronegativity, rendering them ineffective.

K-INN Tech has developed a flame reactor, creating a groundbreaking laboratory-scale system with a capacity of 20 kW (patent No. 102024000021816, dated 02/10/2024). This system can treat concentrated leachate contaminated with PFAS, delivering extraordinary results. The technology ensures intimate contact between fluorinated molecules and flame radicals, achieving their mineralization to HF.

Tests conducted on synthetic contaminated solutions achieved fluorinated molecule mineralization rates of up to 95%, with flame residence times of less than one second.

Our goal is to enhance the understanding of PFAS stabilization processes, study degradation mechanisms, and identify key elements for designing industrial-scale systems.

K-INN Tech is redefining the future of PFAS thermal treatment.
