Wastewater Odour Control Systems and Equipment

Wastewater comes from domestic, commercial, and industrial use, due to the nature, wastewater and sewage can be odorous and unpleasant. Wastewater contains microorganisms and inorganic compounds, which can be harmful, smelly and are often needed to be removed from the water at a waste treatment plant. 

Sewage systems surround us underground, meaning that if not properly maintained and odour is not controlled it can become a noticeable odour nuisance within the community. Not to mention, water treatment stations also not being well maintained can cause odours to become an unpleasant nuisance.

Sewage treatment plants are used to remove microorganisms, and other pollutants from wastewater. Sewage treatment plant odour control will help to reduce the smells in the plants and reduce complaints, making a more pleasant environment for workers. Odour control systems can help with reducing air pollution permitted from sewage treatment plants. Odour suppression misting systems, such as a pacific nozzle-line systems could be implemented as a boundary system, to remove odour within the environment. 

Sewage odour control systems can be implemented to reduce odour on-site and reduce complaints, overall creating a more pleasant environment. As odour nuisance is considered a contribution to air pollution, it also means that controlling odour can be sustainable and beneficial to the environment. There is such things as odour abatement notices which can be issued by the Environmental Agency to businesses emitting bad odours, these have to be solved or will result in a fine being issued or potentially further consequences.

Considering having odour control in wastewater treatment can be beneficial prior to being contacted by the environmental agency as a focus on sustainability and employee wellbeing. Often odour nuisances are known, and many will prioritise reducing and removing odour pollution. Having systems in place to monitor odour within waste treatment plants is beneficial to keep on top of odour control.

Air Spectrum can provide odour control systems to the wastewater industry in the form of misting and fogging equipment. With a wide range of systems to suit individual needs, we can suit a range of issue sizes using our equipment. We have a consultancy and laboratory which can support with odour monitoring. Within our laboratory, odour samples can be taken regularly to assess the impact of odours, ensuring they are low enough to pass Environmental Agency Regulations. 

Once recorded and assessed, if odour emissions are too high odour management plans can be implemented to bring odorous levels down. 

Introducing an all-in-one site monitoring and laboratory analysis service, can provide the wastewater industry with accredited odour emissions data that can assist with, demonstrating compliance with environmental permit and odour efficiency assessments and performance appraisals of biofilter and carbon filter abatement systems.

Effective odour management plans can evaluate the scale and nature of any site odour sources and select the most appropriate control measures that company the the best available technique for the specific industry sector. 

Air Spectrum can offer expert advice from our air quality and laboratory consultants, not only providing assessments and data, but providing management plans to help improve issues on-site and in line with Environmental Agency Regulations. Our odour laboratory is UKAS Accredited and provides objective odour assessment data in accordance with leading international test standards: BS EN 13725. UKAS lab No # 8283. The laboratory operates within an accredited quality management system in line with ISO 17025.
