As a global leader in the water and waste management sectors, we have been operating for over 160 years all over the world. We provide essential services to protect the resource and improve quality of life wherever we operate.
Odour Diagnosis
A comprehensive assessment of emissions allows us to identify the most relevant sources and design an action plan to minimise the impact of the facilities. Usually, these studies must be approached through different strategies to accurately diagnose the problem: Olfactometry studies (based on UNE-EN-13725, UNE-EN-16841 standards), chemical speciation of VOCs through active and passive samplers, on-line detection through nano sensors, greenhouse gas emissions, detection of fugitive emissions through infra-red detectors, among others.
AirAdvanced® Study
Odour pollution has become one of the most significant environmental issues in cities and urban areas. Dynamic olfactometry, a methodology widely accepted by the scientific community in Europe and other countries worldwide, is used to evaluate odour nuisance and develop solutions.
We provide odour diagnosis and control, conducting olfactometric studies based on emission measurements following the UNE-EN 13.725 standard, for which it is accredited by ENAC.
Odour Treatment
Odours can have a significant impact on people's quality of life. Our emission treatment solutions (for H2S and VOC removal, among others), AirAdvanced® Treatment, can enhance your reputation and foster good community relations by addressing unpleasant odours. Our company is proud to offer the Best Available Technology (BAT) on the market, which includes Advanced Biofiltration solutions that meet the most stringent emission limits (500-1000 uoE/m3).
ActiLayer
Innovative solution for the treatment of odorous compounds from surface sources, such as H2S and VOCs as well as greenhouse gases such as N2O.
-
Main benefits: low-maintenance technology that removes a wide range of pollutants with efficiencies up to 80% and consumes no energy. A cost-effective and sustainable option.
-
Business sector addressed: Waste and Water facilities, Food & Beverage, etc.
Advanced Biofilter
Considered the Best Available Technology (BAT) for treating odorous emissions, where final odour concentrations of less than 500 uoE/m3-1.000 uoE/m3 can typically be achieved, which ensures compliance with the strictest odour emission limits.
Thanks to the inoculation of specific microorganisms in the advanced biomedia, it has the capacity to simultaneously purify nitrogen compounds, sulphur compounds and VOCs.
- Main benefits:
• Very high deodorization efficiency from the first day of operation
• Very high mechanical resistance and consequently the useful life of the biomedia is up to 8-10 years compared to the usual 2-3 years in conventional biofilters.
• Operational availability greater than 99%
• Lower pressure drop, as it is a very porous material, which means that the energy costs for ventilation are almost half that of other biofilters.
- Business sector addressed: Waste and Water facilities, Food & Beverage, rendering, etc...
- Time to implement : 20 weeks
Biocassette
A plug-and-play solution based on Advanced Biofiltration which treats odour and H2S (small/medium flowrates).
- Main benefits:
• Requires minimal and simple installation,
• Effectively treats odour and H2S emissions
• Operates with very low water and electricity consumption, making it an energy-efficient and eco-friendly solution
• Excellent purification with a cost-effective solution for treating odorous emissions.
- Business sector addressed: Wastewater pumping stations, biogas plants, Wastewater Treatment Plants.
- Time to implement : 2-3 months
Biotrickling
Highly efficient system in treating emissions with a high presence of hydrogen sulfide (H2S) and odours (small/medium flowrates). It can also purify other Volatile Organic Compounds (VOCs) and it does not produce harmful byproducts, making it a more environmentally friendly option
- Main benefits:
• Able to treat with high-efficiency streams with H2S concentrations between 10 and 500 ppm
• Reduced electricity consumption
• Fast installation and start-up (plug & play), reaching maximum operating efficiency in two weeks.
o 95% H2S removal efficiency
• < 1.500 uoE/m3 Odour concentration at system outlet
• Allows the purification of other odorous compounds besides H2S, resulting in higher deodorization efficiency.
- Business sector addressed: Wastewater Treatment Plants and pumping stations, other industrial facilities (pulp & paper
- Time to implement : 3-6 months
Odour Cover Solution
Covering technology that uses hexagonal-shaped floating pieces, providing a robust, economical, sustainable and long-lasting solution, without the need for additional treatment.
- Main benefits:
• Technology highly durable and reliable,
• Cost-effective as it requires minimal maintenance
• Simple and quick to install
- Business sector addressed: Waste facilities, Wastewater Treatment Plants
- Time to implement : 5-6 months
Regenerative Thermal Oxidation (RTO)
A system that efficiently purifies gases contaminated with Volatile Organic Compounds (VOCs) and other odorous substances.
- Main benefits:
• Purification efficiency of over 99.5% for emissions contaminated with VOCs or odours.
• It can elevate the temperature of the gases to be treated to around 750-850ºC, and up to 950ºC if required, making it versatile for different applications.
• The high efficiency of the system can potentially lead to cost savings in the long run
• Straightforward to operate, requiring minimal manual intervention.
- Business sector addressed: Wastewater Treatment Plants and pumping stations, other industrial facilities (pulp & paper)
- Time to implement : 12-16 months
Hydrocyclone scrubber (Aireco)
Treatment unit for VOCs, odours, noxious and corrosive gases.
- Main benefits:
• Self-cleaning,
• Low-pressure drop
• Small footprint
• Energy recovery
• >85% odour removal efficiency (inlet flux < 25 000 x 103 UOE/h)
• >90% H2S removal efficiency (inlet flux < 1.000 g/h)
• >80% VOC removal efficiency (inlet flux < 1 000 g/h)
- Business sector addressed: Industrial facilities (food, cosmetic, metallurgical, printing, cement manufacturing, petrochemical plant…)
Odour Monitoring
Our monitoring systems, AirAdvanced®, are adaptable and can be tailored to your needs. We can provide real-time monitoring and predictive models, combining emissions, orography, air quality and meteorological modelling to develop studies of dispersion, air quality plans and strategies. We also work to optimize traffic flows to reduce emissions in cities, helping smart city governments to predict areas of poor air quality and reduce air pollution.
Sentinel
- A software solution for monitoring and modelling of odour emissions from your facilities into the environment.
With connected sensors, you can continuously measure pollutants and odour nuisances using software modelling, effectively managing air quality and minimizing your environmental impact.
Other software solutions such as Aria Regional, F-Air, Aria Risk or AriaView have been integrated in AirAdvanced® Sentinel.

Advanced biofiltration at the Galindo Water Treatment Plant (Bilbao)
The Galindo WWTP is managed by the Bilbao Bizkaia Water Consortium, with a treatment volume of 350,000 m3/day, being the largest in the Basque Country. The scope of the project was the supply of the advanced biofilter for the deodorization of the emissions from the sludge line.
Advanced Biofiltration in the Environmental Technologies Park of Mallorca
At the WWTP and RSU sludge biomethanisation plant, in the Parque de Tecnologías Ambientales de Mallorca (TIRME) was carried out the design, supply and commissioning of an odour elimination system including ventilation, ducts, and an advanced biofilter.
