In recent years, with the acceleration of global climate change and urbanization, the problem of eutrophication in water bodies has become increasingly serious, and the proliferation of algae has led to the pollution of odorants (such as geosmin, 2-methylisoborneol, etc.) and algal toxins in drinking water sources and aquaculture. These odorants not only affect the sensory characteristics of drinking water and pose a threat to fishery products, but may also pose a potential threat to human health. Therefore, researching and applying advanced odor detection and prevention technologies has become an important issue in ensuring the safety of drinking water. In order to fully discuss the source, detection method, removal technology, prevention and control strategies and other core issues of odor substances, the "2025 Seminar on Accurate Detection and Comprehensive Prevention and Control of Odor in Urban Water Supply System" and "2025 International Water Association (IWA) Seminar on Odor and Algotoxins in Drinking Water Sources and Aquaculture", jointly sponsored by the Ecological Environment Research Center of the Chinese Academy of Sciences, Shanghai National Engineering Center for Urban Water Resources Development and Utilization, Xi'an University of Architecture and Technology, Zhejiang University, and organized by Shanghai Water Purification Technology Magazine, are scheduled to be held from August 28 to September 1, 2025.

Instrument exhibited this time: Electronic Nose Odor Detector

As a pioneer in the commercial application of electronic noses worldwide, AIRSENSE, a German company, has developed the PEN3.5 portable odor analyzer. Through biomimetic olfactory sensing technology, it can simulate the human olfactory system to accurately perceive, analyze, and judge odors. This device combines the advantages of small size, portability, fast response, and high-precision detection, and is equipped with powerful intelligent analysis software. It can not only display odor concentration (OU value) in real time, but also achieve pollution traceability analysis and identification of odor key factors. PEN3.5 electronic nose provides efficient technical means for water quality safety warning and pollution control with these technological advantages, especially suitable for odor monitoring needs in scenarios such as drinking water sources and sewage treatment plants.
Instrument for this exhibition: Water body odor detector

The WOD-1 water odor detector is an instrument independently developed by our company specifically for rapid detection of water odor. The instrument adopts mainstream metal oxide sensor array electronic nose technology, with a built-in sample pretreatment device, which can quickly analyze the odor intensity level and odor concentration OU value of water samples with one click, or qualitatively judge and analyze the type of water.

Welcome to the conference venue to discuss with us:
1. Detection scheme for different odorants in water sources;
2. Research plan for odor fingerprint method in water;
3. Detection plan for odor levels in drinking water bodies;
4. Monitoring plan for sulfides and odors in sewage treatment plants;
