Gas scrubbing systems for every application
From odour biofiltration to regenerative thermal oxidation, our range covers every need for the treatment of gaseous emissions. Select a technology to see the details.

Biofiltration: TECNIUM-BIO
Gas scrubbing and odour removal systems using organic and inorganic biofilters. An environmentally clean technology that has driven research in gas purification over recent decades, offering high capacity and low operating cost.

Biotrickling: TECNIUM BIO-TR
High-efficiency biotrickling that allows existing installations to be converted by removing the chemical route, eliminating reagent consumption and therefore the storage of chemical products and APQ periodic inspections.

TECNIUM-CHEM Absorption
Multiple systems for gas scrubbing and odour control by absorption with water or chemical reagents, using scrubbing towers, venturis and cyclones adapted to each industrial application with maximum removal efficiency.

TECNIUM-K High-End Adsorption
Gas scrubbing and odour removal processes using high-end filter media. Includes adsorption with impregnated activated aluminas combined with various types of activated carbon and zeolites for highly selective pollutant capture.

TECNIUM-CARB Activated Carbon
Gas scrubbing and odour removal processes using porous filter media. Includes impregnated or non-impregnated activated carbons, catalytic, water-regenerable and thermally activated grades for a wide range of pollutants.

TECNIUM-DEGAS Stripping
Systems for groundwater, well water, landfill leachates, manure and ultrafiltered water that may contain dissolved gases that need to be removed before further treatment or discharge.

TECNIUM-RTO Thermal Oxidation
Regenerative thermal oxidation (RTO) for the removal of polluting emissions through high-efficiency incineration. Thermal destruction process for complex organic compounds and VOCs with destruction efficiencies above 99%.
Gases and compounds our systems remove
Our technologies are proven against a wide range of atmospheric pollutants present in industry.
Common questions about TECNIUM gas scrubbing technologies
The choice of technology depends on the type of pollutant, its concentration, the airflow to be treated, applicable regulations and site conditions. Biofiltration (TECNIUM-BIO) is ideal for odours and biodegradable compounds; chemical absorption (TECNIUM-CHEM) for acid gases such as HCl, HF or SO₂; activated carbon adsorption (TECNIUM-CARB) for VOCs; and thermal oxidation (TECNIUM-RTO) for complex organic compounds. Our engineering team carries out free emission characterisation studies to recommend the optimal solution.
TECNIUM gas treatment systems can treat flows in excess of 500,000 m³/h. For very high flows, modular configurations are designed with multiple stages in parallel. Every project is custom-sized according to the specific process conditions of the installation.
Biofiltration (TECNIUM-BIO and BIO-TR) is an environmentally clean technology that does not require storage or consumption of chemical reagents, eliminating APQ periodic inspections and significantly reducing operating costs. It is particularly effective for odours and biodegradable compounds. Chemical absorption (TECNIUM-CHEM) offers greater efficiency for concentrated acid gases but requires the handling of chemicals.
TECNIUM technologies are applied in a wide variety of sectors: chemical and pharmaceutical industry, wastewater treatment plants (WWTP), mechanical-biological waste treatment plants (MBT), landfills, fertiliser industry, surface treatment, mining, food industry and petrochemicals, among others. Each sector presents specific challenges for which TECNIUM selects the most appropriate technology or combination of technologies.
All TECNIUM gas treatment systems are designed to comply with applicable environmental regulations, both European and local. Sizing takes into account the emission limits set by current legislation and the Best Available Techniques (BAT). TECNIUM has extensive experience in projects requiring strict regulatory compliance in more than 20 countries.
