CATOX Technology for Air Treatment

A grey veolia box with CATOX technology

Challenge:

Environmental and industrial projects require reliable, cost-effective air treatment systems that can handle varying contaminant concentrations while minimizing operational costs and environmental impact. Soil remediation sites need efficient vapor treatment during extraction operations. Industrial facilities must control VOC emissions from manufacturing processes. Landfill operations require management of contaminated gas streams. Traditional thermal oxidation systems consume excessive energy at temperatures exceeding 800°C, while biofilters struggle with high concentrations and activated carbon systems generate significant disposal costs. Sites with limited space face additional challenges in accommodating bulky treatment equipment, particularly in urban environments or existing industrial facilities.

Solutions:

CATOX is an advanced catalytic oxidation system designed for treating contaminated air streams in soil vapor extraction, remediation projects, industrial emissions control, and landfill gas management. As the market leader in Europe for this specialized technology, CATOX delivers superior performance with exceptional energy efficiency and a compact footprint. The system employs catalytic oxidation at operating temperatures of just 300-450°C—significantly lower than conventional thermal oxidation systems. Our proprietary heat exchanger design maximizes energy recovery, achieving 50-70% lower fuel consumption while maintaining destruction efficiencies exceeding 99% for volatile organic compounds (VOCs), BTEX (benzene, toluene, ethylbenzene, xylene), and chlorinated hydrocarbons. The ultra-compact design fits spaces as confined as a garage, making it ideal for sites with limited footprint availability. Standard units handle flow rates from 100 to 2,500 m³/h, with custom solutions available for unique project requirements. Automated PLC control with remote monitoring ensures reliable operation with minimal on-site supervision, while automatic dilution protection manages high concentration events safely. Our flexible delivery models—Build-Own-Operate (BOO), Build-Operate-Transfer (BOT), and Engineering-Procurement-Construction (EPC)—ensure the right solution for every project's financial and operational requirements.
