Manure
Areas of intensive livestock farming generate liquid effluents known as manure (slurry) which, owing to their high pollution load, must be treated before final discharge. The various treatment processes produce gaseous emissions that must be scrubbed.
TECNIUM has solid references for the scrubbing of gases from manure-drying plants and for degassing facilities of the ammoniacal leachates produced in this type of plant.
Gaseous emissions and ammoniacal leachates in manure plants
Manure treatment generates polluting gaseous emissions and leachates with a high ammonia content that must be treated before discharge.
Gaseous emissions and dissolved NH₃
Intensive livestock operations generate large volumes of manure whose treatment produces gaseous emissions with a high content of ammonia (NH₃) and other compounds that must be scrubbed before being released to the atmosphere. In addition, anaerobic digestion processes generate leachates containing dissolved NH₃ which must be removed.
- Gas scrubbing in manure-drying plants
- Degassing of ammoniacal leachates
- Removal of dissolved NH₃ before discharge
- Treatment of anaerobic digestion emissions
- Compliance with environmental regulations
- Materials resistant to NH₃ corrosion
Two needs, two technologies
The manure sector presents two distinct needs: on the one hand, the scrubbing of contaminated gases from drying plants, where chemical absorption technology (TECNIUM-CHEM) is applied; on the other, the degassing of leachates with dissolved NH₃, where degassing technology (TECNIUM-DEGAS) is applied.
TECNIUM has both technologies and the experience required to size the optimal equipment for each application in manure treatment plants.
Applications in manure treatment plants
TECNIUM provides specific solutions for gas scrubbing and leachate degassing in the livestock sector.
Wet absorption of contaminated gases
Gas scrubbing systems based on wet absorption for the removal of the polluting gaseous emissions generated in manure-drying plants. Scrubbing towers and scrubbers designed to capture and neutralise NH₃ and other contaminants.

Leachates in manure treatment plants
Manure treatment plants based on anaerobic digestion for the production of biogas (methane) generate liquid residues (leachates) which usually carry dissolved NH₃ that must be degassed before these waters are discharged.

Our systems are engineered to treat the gaseous emissions and dissolved compounds generated in manure treatment.
Two technologies for manure treatment
TECNIUM has two complementary technologies to cover the needs of the sector: chemical absorption and degassing.
TECNIUM-CHEM
Under this technology TECNIUM supplies multiple systems for gas scrubbing and odour control through absorption with water or chemical reagents, using scrubbing towers, venturis and cyclones.

TECNIUM-DEGAS
Groundwater, well water, landfill leachates, manure and ultrafiltered water may contain dissolved gases that need to be removed before any further treatment or discharge. TECNIUM has the technology required for this duty.

Common questions about gas treatment in manure plants
TECNIUM offers two main solutions for the manure sector: gas scrubbing systems based on chemical absorption (TECNIUM-CHEM) for treating the gaseous emissions from manure-drying plants, and degassing systems (TECNIUM-DEGAS) for the removal of dissolved NH₃ from the leachates generated in anaerobic digestion plants.
Manure treatment plants based on anaerobic digestion produce biogas (methane) and generate liquid residues called leachates. These leachates usually contain dissolved NH₃ (ammonia) which must be removed before the water can be discharged. The TECNIUM-DEGAS technology is specifically designed for this degassing process.
Manure drying generates gaseous emissions with high concentrations of ammonia and other polluting compounds. TECNIUM-CHEM technology uses scrubbing towers with wet absorption (water or chemical reagents) to capture and neutralise these emissions, ensuring compliance with the emission limits set by the applicable regulations.
TECNIUM-CHEM is a chemical absorption technology for the treatment of contaminated gases: it uses scrubbing towers, venturis and cyclones to capture gaseous emissions. TECNIUM-DEGAS is a degassing technology for the removal of gases dissolved in liquids (such as NH₃ dissolved in leachates). Both are complementary and are applied at different stages of the manure treatment process.
Yes. TECNIUM systems are designed and sized to comply with the environmental regulations applicable to the livestock sector, both for gaseous emissions to atmosphere and for the quality of discharged waters. The TECNIUM engineering team sizes each installation to guarantee compliance with the established limits.
Yes. TECNIUM has a specialist engineering team that can advise on the selection of the most appropriate technology (CHEM, DEGAS or the combination of both) according to the specific characteristics of your manure treatment plant: type of process, flow rates, contaminant concentrations and applicable regulations.
