FPI Ensures Water Quality and Provides Emergency Control Platform for Blue-Green Algae during Asian Games

To ensure the water safety of the Asian Games, FPI provide related products to prevent cyanobacteria invasion.

In accordance with the requirements of the 100-day countdown to the Asian Games, various government bodies in Zhejiang Province and Hangzhou City came together to organize a special event. On Wednesday afternoon, the 14th of June, the Water Management Office, the Department of Ecology and Environment, the Water Management Office of Hangzhou, and the Ecology and Environment Bureau of Hangzhou joined forces to host a rehearsal that simulated an infestation of cyanobacteria in the affected cities during the Asian Games using a combination of online and offline methods, from the dissemination of early warning responses to the development of response plans and the eventual lifting of the alarm. Environmental departments from Quzhou, Shaoxing, and Jinhua also participated in the exercise.

The technical support unit of the platform, FPI, was involved in the entirety of the exercise. In addition to various crucial responsibilities, the platform construction concepts primarily focused on safeguarding outdoor aquatic competition zones, preserving the water surrounding the stadium, ensuring the integrity of the drinking water source, preserving the marine ecosystem, and mitigating cyanobacterial blooms in the water. The platform facilitates the rapid acquisition of knowledge pertaining to outdoor water-related areas, their associated venues, sources of potable watToer, marine water ecosystems, water quality, monitoring data and trends, a comprehensive map illustrating the interconnections between water quality and algae status, identification of risk points for cyanobacteria-contaminated water, and provision of early detection and warning systems to ensure the successful execution of the Asian Games.

Algae in river water bodies tend to proliferate and breed in warm weather every summer, polluting water bodies and posing a significant risk to water sports and the drinking water supply.

By constructing a cyanobacterial emergency control platform, it is possible to provide comprehensive environmental status control, consultation on decision-making, control and scheduling, early warning, and closed-loop task management, among other tasks. The platform accomplishes the visualization of water quality and hydrological data, rapid problem detection, automatic warning, linkage disposal, closed-loop management, real-time monitoring, timely warning, and precise surveillance of cyanobacteria in water bodies. The following are particular cases:

1.Data support

Real-time monitoring of crucial pollutants is conducted to gain insights into various water bodies, including general water bodies, drinking water sources, and river outfalls. This monitoring also aims to identify key pollution sources and other control objects and risk sources associated with the pollution situation. The data collected through this monitoring process serves as a foundation for conducting risk research and making informed judgments.

2.Risk Alert

The platform facilitates enhanced comprehension of meteorological monitoring and forecasting outcomes, as well as the flow and water level of significant hydrological stations. It also investigates and evaluates the influence of water and rainfall on the water environment while concurrently generating early warnings by utilizing data collected from water quality and algae monitoring stations. This approach aims to optimize the promptness of problem resolution.

3.Process tracking

5.In instances where there is a potential for a cyanobacteria outbreak, a comprehensive monitoring process is undertaken, encompassing various stages such as the issuance of warnings, response to warnings, decomposition of tasks, tracking of implementation, and concluding with the assessment of warnings. These dimensions facilitate a prompt evaluation of the enforcement of control measures in cities that have been alerted, enabling the reporting of emergency monitoring data and reports.

4.Review and evaluation

In instances where there is a requirement for specialised investigation and assessment pertaining to algae, one may delve into the subject matter encompassing the status of algae blooms, the impact of upstream factors, the disposal of warnings, the dissemination of instructions, the provision of feedback on implementation, as well as the tracking and evaluation of related activities. In order to gain comprehension of the process of cyanobacteria control, it is advisable to undertake a thorough examination and analysis of past instances of risk control.

FPI Water Environment Cyanobacteria Emergency Control Platform

To safeguard the ecological water environment, FPI has autonomously established a cyanobacteria emergency control platform for the water environment. This platform has been integrated with a range of internally developed equipment for monitoring water quality pollution. The objective is to enable real-time monitoring of nutrients, Chlorophyll A, and the composition and concentration of algae in water bodies. This comprehensive monitoring system is designed to effectively address the requirements of algae monitoring and emergency control.

The BFA-3000, an in vivo fluorescence algae classifier, was designed and developed by FPI. This device utilizes fluorescence spectroscopy to measure various parameters related to algae, including the density and concentration of cyanobacteria, green algae, diatoms, methanogens, and cryptophytes. Additionally, it can determine the total Chlorophyll A content, overall algae density, and water depth. The utilization of multi-wavelength light excitation enables the differentiation of various algae classifications and facilitates the measurement of algae density. This approach proves beneficial in conducting vertical distribution analysis of diverse algae within a water body. The utilization of the integrated multi-light path background deduction algorithm allows for the deduction of the impact caused by fluorescent organic matter, colored substances, turbidity, and other factors. Consequently, the obtained results exhibit a higher degree of accuracy. Additionally, the shell possesses a robust structure that enables the measurement of algae at depths of up to 200 meters underwater. The integration of compatibility design can be applied to unmanned vessels, conventional water stations, and pontoon stations to effectively address the requirements of water flora monitoring in various aquatic environments such as rivers, lakes, oceans, and other types of water bodies.

The FPI-developed SUPERC 8020 full spectrum flow algae analyzer utilizes a fluorescence full spectrum system to capture real-time images of algal organisms as they traverse the system. This system records pulse spectra, assigns numerical identifiers, digitizes various characteristics (such as effective diameter, length, width, aspect ratio, chromaticity, etc.), and stores this data for algae identification. The flow full spectrum and high-speed imaging technology platforms are utilized to acquire multi-dimensional information, including images and fluorescence, of algae. These platforms employ spectral data processing and AI deep neural network image processing techniques to achieve precise detection outcomes for algae.

FPI possesses both the capability for independent research and development and the production of advanced analytical instruments such as chromatography, spectroscopy, and mass spectrometry. Additionally, FPI has demonstrated expertise in the construction, operation, and maintenance of intelligent integrated management platforms. The independently developed integrated management platform for the water environment has gained extensive utilization among environmental protection, water conservancy, housing, and construction departments across different provinces and municipalities. This platform has the potential to significantly enhance the standard of common management and protection of the water environment. It can promote harmonious coexistence between humans and water by employing precise monitoring and intelligent supervision of the water ecological environment.
