Industrial Odour Control & Abatement Solutions
Donaldson Group provides industrial odour control and abatement solutions designed around the source of the emissions, the contaminants present and the operating conditions of the process.
From initial investigation and odour assessment through to system design, installation and ongoing support, we develop practical solutions for new and existing industrial facilities across the UK.
Understanding the Odour Comes First
Effective odour control starts with understanding the source of the emissions and the contaminants present.
Industrial odours can contain a complex mixture of compounds, and a treatment technology that performs well in one application may be completely unsuitable for another.
We consider the process itself alongside factors such as airflow, contaminant concentration, temperature, humidity and variations in operating conditions before recommending a treatment approach.
Typical contaminants include:
Hydrogen sulphide (H₂S) • Ammonia & amines • VOCs • Sulphur compounds • Organic process odours • Oil mist & aerosols • Particulates
Where required, Donaldson can assist with odour assessment, sampling and testing to establish the nature of the emissions before developing a treatment strategy.
Selecting the Right Treatment Technology
Donaldson Group is not tied to one manufacturer or one treatment technology. Our approach is to understand the application first and then select or combine technologies according to the contaminants, airflow and process conditions.
Activated Carbon & Specialist Media
Activated carbon and specialist adsorption media can provide highly effective treatment of industrial odours, VOCs, hydrogen sulphide and other gaseous contaminants. Correct media selection, contact time, airflow and bed design are critical to achieving effective treatment and reasonable media life.
Wet & Dry Scrubbing
Scrubbing systems can be used where contaminant concentrations or gas characteristics make chemical treatment appropriate, including applications involving acidic or alkaline gases, ammonia and sulphur compounds.
Biological Treatment & Biofiltration
Biological treatment can provide an effective solution for suitable biodegradable odour compounds, particularly where relatively large air volumes require treatment.
UV & Oxidation Technologies
UV and oxidation technologies can be incorporated where appropriate, either as a primary treatment stage or in combination with other technologies.
Multi-Stage Odour Control
Some applications cannot be treated effectively with a single technology. Donaldson can develop multi-stage systems combining technologies such as pre-filtration, scrubbing, oxidation and activated carbon to progressively remove contaminants before treated air is discharged.
Industrial Applications
Donaldson provides industrial odour control solutions across a wide range of processes and industries. Each application presents different contaminants, air volumes and operating conditions, so the treatment approach is developed around the individual process rather than a standard off-the-shelf solution.
Anaerobic Digestion & Biogas
Control of H₂S, ammonia and organic odours associated with feedstock reception, processing, digestate handling and associated operations.
Waste & Recycling
Odour control for waste reception, storage, processing, transfer stations and enclosed treatment areas.
Food Processing
Treatment of cooking, processing, organic, oil and other production-related odours from food manufacturing and processing facilities.
Wastewater & Sewage Treatment
Control of hydrogen sulphide and other odorous emissions from tanks, pumping stations, treatment processes and enclosed areas.
Manufacturing & Industrial Processes
Treatment of VOCs, solvent vapours, chemical emissions and process-specific odours from manufacturing and industrial operations.
New Systems & Existing Installations
Not every odour problem requires a completely new system. Donaldson can design new odour control installations as well as investigate existing systems where performance has deteriorated, operating conditions have changed or the original treatment process is no longer achieving the required results.
For existing installations, we can assess airflow and extraction performance, fan and ductwork design, filter condition, pressure drop, activated carbon and media selection, contact time and changes within the production process.
Where appropriate, an existing system can often be modified, reconfigured or upgraded with additional treatment stages rather than completely replaced.
Our approach is simple: understand why the existing system is not performing before recommending what needs to change.
Talk to Us About Your Odour Problem
If you are experiencing an industrial odour problem, planning a new facility or
looking to improve the performance of an existing odour control system, talk to Donaldson.
Every application is different. We can start with an initial discussion about your process, the nature of the emissions
and the problems you are experiencing before deciding whether further investigation, testing or a site visit is required.
From identifying the problem to developing the solution, we’re here to help.
