Wastewater treatment plants are treating more wastewater than ever, and processing volumes are growing each year. As processing volumes grow, treatment works get upgraded or extended, and odour controls should follow suit. However, it is common for a gap to form between wastewater treatment and odour control, creating inefficiencies in the odour removal process.  If your odour control process is not […]

Refineries have their work cut out to control odours and reduce noxious, unpleasant emissions, but with good strategy and advice from experts, it’s possible to abate odours while minimising waste and energy usage.  The following odour management guidance for refineries provides an introduction to odour management. For personalised advice, please contact us. Legislation In the […]

Odour control is an ongoing requirement for industrial oil refineries. Unavoidably, oil refineries produce strong nuisance odours from handling, storing and processing oils, as well as manufacturing fuels, greases and lubricants. Refining crude oil down into its various components releases sulphides, mercaptans and hydrocarbon compounds. Oil refineries also have to contend with odours from combustion, […]

An odour impact assessment is a survey assessment that provides a qualitative analysis of the impacts of odours within a local vicinity.   Odour impact assessments are a critical part of odour control policy because they provide unique information on the impact of industrial and commercial activities, enabling operators to take action by resolving identified […]

Odour control system performance testing involves physical and automated tests of odour control systems to find problems and assure performance.  Performance tests are conducted following the installation, upgrade and repair of odour control systems to certify performance, design and capabilities. Periodic tests can also be performed to track system degradation.   The importance of performance […]

With organic waste levels increasing in line with a growing population, organic waste facilities have their work cut out to meet capacity. Investment in in-vessel composting facilities, including containers, silos, agitated bays and enclosed halls has soared. Still, an often unspoken aspect of organic waste treatment – odour control – has seen soaring investment too. […]

When not controlled adequately, industrial emissions cause significant air pollution, and odorous compounds in these emissions can lead to community complaints and abatement notices from your local council. This makes odour control a key consideration for industrial emission treatment, no matter the scale of the operation. The following odorous compounds are common in industrial emissions: […]

Organic waste facilities produce a variety of foul odours, with gaseous ammonia (NH3) and hydrogen sulphide (H2S) being the biggest culprits. Potential sources of odour in organic waste facilities include: Composting activities Foul surface water Residual wastes for landfill Storage prior to processing Odour management for organic waste facilities involves reducing odorous gases that are […]

If your industrial operation generates noxious/toxic organic gases, passive filters are the simplest way to filter vent gases on storm, sludge, sewage and waste holding tanks, fume exhaust cupboards and pump sumps under positive pressure. We typically specify passive filters when there is a need to vent otherwise noxious and unpleasant gases out into the […]

Odour monitoring in biogas projects is an essential stage of odour management. It is necessary to ensure that biogas production does not impact the local population. It can also help us locate and identify inefficiencies in equipment. Biogas and odours Because modern biogas production takes place in a hermetic environment, biogas plants shouldn’t produce unpleasant […]

Wastewater treatment plants produce significant volumes of odour that must be treated before contaminated air can be exhausted outdoors.   Most odours produced during wastewater treatment result from anaerobic decomposition of organic matter. Sulphur, nitrogen and methane are released during this process, as are H2S and ammonia. The result is a potent mix of gaseous […]

We might be pointing out the obvious, but the best odour control system is the one that works. Different odours call for different solutions and the type of work you do, including the equipment you use, will determine the design of your system. Design and Build We offer a complete design and build service to […]

Food factories generate significant volumes of odour the most offensive of which is hydrogen sulphide gasses (H2S). This smells like rotting eggs and is intolerable. Food processing also generate VOCs, aldehydes, ketones, alcohols, acids, ammonia, amines and mercaptans which can be equally offensive. Add fats, greases, sludges, slurries and high temperatures to the mix, and […]

Odours are a by-product of many industrial processes, including wastewater treatment, incineration, crude oil refinement, chemical processing and food production. These odours become a problem when they cause a nuisance. This can lead to complaints and attract attention from councils who can serve an abatement notice. There are several technologies we can use to control […]

When industrial odours aren’t controlled they pollute the local environment. This is unpleasant for members of the public and other local businesses. It can also create poor working conditions that affect employee health and morale. From an environmental perspective, air pollution is bad news because it affects the quality of the air we breathe. While […]

Problem odours are a by-product of many industrial processes such as wastewater treatment, incineration and chemical processing. These odours must be controlled to minimise their impact on the environment. The common problems in odour control include: How to define and characterise what odours are being produced Selecting and sizing the correct odour control system Creating […]
