From August 28th to September 1st, 2025, the "2025 Urban Water Supply System Odor Precision Detection and Comprehensive Prevention and Control Technology Seminar" and the "2025 International Water Association (IWA) Odor and Algal Toxins Seminar in Drinking Water Sources and Aquaculture" were successfully concluded at the Dahua Jinxiu Huangguan Holiday Hotel in Shanghai. As an innovative enterprise in the field of environmental monitoring, Tianjin Runze Instrument Co., Ltd. showcased two core water odor detection instruments at this grand event that gathers global industry wisdom. With advanced technology, professional solutions, and in-depth exchanges, Tianjin Runze Instrument Co., Ltd. injected new vitality into the field of water odor prevention and control and water safety assurance, and gained widespread attention and recognition from the industry.

Part1
Double convergence of wisdom, discussing core issues of water safety together

● Exhibition site
The two concurrent events focused on the pain points of odor substances (such as geosmin and 2-methylisoborneol) and algal toxin pollution caused by global eutrophication of water bodies, and conducted in-depth discussions on core themes such as "protection of drinking water sources, prevention and control of harmful algae, odor detection technology, water plant removal processes, and improvement of aquaculture water quality". Participants from domestic research institutions, water supply companies, environmental protection units, and the aquatic industry shared their latest research results and practical experience through thematic reports, technical exchanges, on-site seminars, and other forms, jointly exploring effective solutions to address water odor and algal toxin pollution. This is not only a "smart collision" for the industry to address environmental challenges, but also a key bridge for the practical application of detection technology.
Tianjin Runze Instrument, as a representative of participating companies, fully participated in the conference discussions and deeply grasped the industry's needs: from precise traceability of odor substances in drinking water sources, to monitoring of odor levels in water treatment plants, and to monitoring of odor emissions in sewage treatment plants, every link urgently needs efficient, convenient, and high-precision detection tools. This further strengthens our direction of responding to industry pain points through technological innovation, laying a practical foundation for the instrument display and scheme exchange at this exhibition.

Part2
Hardcore instruments debut, showcasing the strength of detection technology

At the exhibition site, Tianjin Runze Instrument showcased two core devices for water odor detection. With their technological advantages of "precision, speed, and portability", they became the focus of the venue and attracted many participants to stop and consult, exchange experiences.

01
PEN3.5 Electronic Nose Odor Detector
As a partner of AIRSENSE, a pioneer in the commercial application of electronic noses, Tianjin Runze Instrument has introduced the PEN3.5 electronic nose odor detector, which relies on biomimetic olfactory sensing technology and simulates the human olfactory system. It can perceive, analyze, and judge odors in water and the environment in real time. Its advantages directly hit the pain points of the industry:
Portable and efficient: The device is compact and lightweight, and can be flexibly applied to on-site scenarios such as drinking water sources and sewage treatment plants, without the need for complex laboratory operations, achieving "instant testing";
Accurate and comprehensive: Not only can it display odor concentration (OU value) in real time, but it can also complete pollution traceability and odor key factor identification through intelligent analysis software, providing accurate data support for pollution control;
Quick response: Shorten the detection cycle, avoid the problems of time-consuming and complicated traditional detection methods, and help enterprises and environmental protection departments improve emergency monitoring efficiency.

02
WOD-1 water odor detector
The WOD-1 water odor detector, independently developed by Tianjin Runze Instrument, is a customized tool designed specifically for domestic water odor detection scenarios. This instrument adopts mainstream metal oxide sensor array electronic nose technology and is equipped with an integrated sample pretreatment device, which balances ease of operation and detection accuracy
One click operation: Without the need for complex training by professional personnel, one click can complete the analysis of odor intensity level and odor concentration (OU value) of water samples, as well as qualitative judgment of water types;
Local adaptation: Based on the actual pollution characteristics of domestic drinking water sources and aquaculture water bodies, optimize detection parameters to better meet the application needs of domestic industries.

Part3
Dialogue industry, jointly drawing a new blueprint for technological applications

During the exhibition, the technical team of Tianjin Runze Instrument had multidimensional and in-depth exchanges with the attending guests, focusing on the four core application scenarios, deeply integrating instrument technology with actual needs, and providing customized solutions for the industry:
Full cycle monitoring of drinking water sources: Provide innovative technical solutions to address the changes in odor substances in different seasons and regions of water sources, and assist in early warning of pollution risks;
Construction of odor fingerprint map: Assist scientific research institutions in collecting odor detection data from different water bodies, construct regional and seasonal odor fingerprint maps for water bodies, and provide data support for pollution tracing and cause analysis;
Process optimization for water supply enterprises: providing a full process odor monitoring tool for water supply enterprises from source water, sedimentation tank water, filtered water to pipeline water, helping enterprises accurately locate odor exceeding links and optimize treatment processes;
Aquaculture water quality control: In response to the problems of increased mortality and quality decline of fish and shrimp caused by water odor in aquaculture, portable detection instruments are provided to help farmers monitor water quality in real time and adjust the breeding environment in a timely manner.

● Meeting Summary/SUMMRY
This exhibition is not only a window for Tianjin Runze Instrument to showcase its technological achievements to the industry, but also an opportunity to listen to demand and optimize products. In the future, we will continue to deeply cultivate the field of environmental monitoring, focusing on core directions such as water odor detection and algal toxin analysis, and continuously providing technical solutions to contribute more "moisturizing power" to ensuring drinking water safety, promoting healthy development of aquaculture, and ecological environment governance.
