A prominent player in the specialty chemicals industry, an existing customer of DESOTEC, faced a critical odour problem at their wastewater treatment plant. While DESOTEC had previously provided filtration solutions for chemical purification, the company now required odour treatment for their ventilated wastewater buffer tank.

VOC screening tests revealed significant concentrations of odorous compounds in the plant, particularly alcohols (757 µg/m³) and organic sulphur compounds (1,846 µg/m³). These volatile compounds, especially dimethyldisulphide and 2-ethyl-1-hexanol, had very low odour thresholds, leading to complaints from both employees and nearby residents, especially during summer months when temperature fluctuations exacerbated the issue. 

The company needed a rapid and effective solution to mitigate the odour and maintain its reputation.

The key benefits of DESOTEC’s filtration solution include:

• Plug & Play installation: Fast setup with minimal disruption to operations.
• No production downtime: Filter exchanges are performed without interrupting business activities.
• Waste management: DESOTEC handles all waste off-site, eliminating the need for customer involvement in waste disposal.
• Sustainability: The circular solution reactivates carbon, reducing the overall environmental footprint.
• Complete odour removal: Highly effective in eliminating odour complaints, ensuring regulatory compliance and maintaining community relations.

This successful collaboration highlights the trust the customer placed in DESOTEC’s expertise, reinforced by the proven performance and ease of implementation of the mobile filtration solution.
