H2S Online Monitoring System in a Sewage Treatment Plant

Release time:2026-01-17

Source:Skyeaglee

In the complex environment of sewage treatment plants, hydrogen sulfide (H₂S), a colorless, highly toxic, flammable, and explosive gas, poses a major risk to operational safety and facility stability. To address this industry challenge, our Skyeaglee factory leverages deep expertise in gas detection technology to offer customers an innovative, low-cost electrochemical online H₂S monitoring system. This solution provides accurate, reliable, and economical protection, building a robust safety barrier for sewage treatment operations. Below, we present this case study.
1. Accurate H₂S Monitoring​
Optimized for sewage treatment scenarios, the system offers a detection range of 0–100 ppm, enabling high-precision, high-resolution gas concentration measurements. Whether detecting daily low-concentration leaks or sudden high-concentration accumulations, the system responds in real time and issues timely alerts, providing reliable data to support safety decisions.
2. Patented Intermittent Sampling for Extended Lifespan​
Conventional continuous sampling exposes sensors to corrosive gases and humid environments for prolonged periods, leading to rapid poisoning, aging, and failure. Our system employs an intelligent intermittent sampling strategy, activating sampling and analysis only during set cycles while keeping the sensor protected in a clean environment during idle times. This design fundamentally prevents continuous sensor poisoning, extends the core component's service life severalfold, and significantly reduces long-term maintenance and replacement costs.
3. Advanced Electrochemical Principle for Excellent Cost Efficiency​
The system utilizes mature and stable electrochemical detection technology, ensuring monitoring accuracy and response speed while effectively controlling hardware costs. Leveraging proprietary core sensor technology and economies of scale, we offer a solution with far higher cost performance than comparable products on the market, making efficient and reliable safety monitoring an affordable investment.
 
Real-World Application Scenario
Why Choose Our Solution?​

  • Professional Customization:​ Tailored installation and configuration options address gas dispersion characteristics in different risk areas such as pump stations, inlet tanks, and sludge treatment zones.
  • Stability and Reliability:​ Industrial-grade design ensures strong anti-interference, dustproof, and waterproof performance, adapting to harsh plant conditions.
  • Smart Connectivity:​ Supports multiple signal outputs including 4–20 mA, RS485, and wireless transmission, enabling seamless integration with existing DCS, PLC systems, or cloud monitoring platforms for centralized monitoring and remote management.
  • Low Maintenance Requirements:​ The intermittent sampling design, combined with sensor self-diagnostic functions, significantly reduces on-site calibration and maintenance efforts, saving labor costs.
