Application case of FSEC 3800 CL2 analyzer in medical wastewater monitoring
—— Water quality monitoring project of the Second Affiliated Hospital of Guangdong Medical University
1、 project context
As a tertiary hospital, the Second Affiliated Hospital of Guangdong Medical University generates approximately 200 tons of medical wastewater daily. According to the 'Emission Standard for Water Pollutants from Medical Institutions' (GB 18466-2005), medical wastewater must undergo strict disinfection to ensure that the residual chlorine concentration is maintained within the range of 0.5-5.0 mg/L, which helps prevent the spread of pathogens and minimize environmental harm. Traditional manual testing methods suffer from issues such as poor timeliness, discontinuous data, and complex operations, making it urgent to adopt high-precision automated monitoring equipment.
2、Equipment selection: FSEC3800 CL2 analyzer
The FESKS FSEC 3800 CL2 analyzer is based on the constant voltage method and has the following technical advantages:
1. High precision measurement: resolution 0.001 mg/L, error less than ±2%, meet the requirements of national standards.
2. Strong anti-interference: built-in multi-wavelength compensation algorithm, effectively eliminate water turbidity, chromaticity and organic matter interference.
3. Fully automatic operation: 24-hour continuous monitoring is supported, data is refreshed every 10 seconds, and abnormal values are automatically alarmed.
4. Remote monitoring compatibility: equipped with RS485/4-20mA output interface, networked with hospital environmental protection platform and local regulatory authorities.
5. Low maintenance design: no membrane head, no reagent, easy to clean, reducing the cost of manual maintenance.
3.Application scheme
1. Installation and deployment
Monitoring point: the discharge outlet at the end of the hospital wastewater treatment station.
• Supporting equipment: constant current sampling system is installed to adapt to the complex composition of medical wastewater.
2. Data management
• Real-time display of residual chlorine concentration curve, generate daily/monthly/year report.
• The data exceeding the standard will automatically trigger the sound and light alarm, and be pushed to the hospital logistics management platform simultaneously.
3. Linked control
• Linked with the PLC of the wastewater treatment system to realize dynamic adjustment of disinfectant dosage and ensure that the residual chlorine is stable and up to standard.
4. Implementation effect
1. Improve monitoring efficiency
• Realize the second-level monitoring of residual chlorine concentration in wastewater, which improves the efficiency by 90% compared with traditional laboratory testing.
• Operation data in 2024 show that the effective operation rate of the equipment is 99.3% and the false alarm rate is less than 0.5%.
2. Emission compliance rate
• The stability of residual chlorine control is improved, and the annual discharge data are 100% in line with GB 18466-2005 standard.
3. Economic benefits
• The annual labor testing cost is saved about 120,000 yuan, and the consumption of disinfectant is reduced by 15% after optimization.
4. Social benefits
• Provide reliable data support for Guangzhou Municipal Bureau of Ecology and Environment, and help hospitals pass environmental supervision and acceptance.
5. User evaluation
The head of the environmental protection department of the Second Affiliated Hospital of Guangzhou Medical University said:
"FSEC 3800 more chlorine analyzer solves the pain point of medical wastewater monitoring, the data is accurate and reliable, greatly reducing the operation and maintenance pressure
Power. Its remote management function is seamlessly connected with the hospital's intelligent logistics system, providing technical support for the construction of green hospitals."
Vi. Industry promotion value
This case verifies the applicability of FSEC 3800 in medical wastewater scenarios, which can be replicated to high-risk wastewater treatment scenarios such as infectious disease hospitals and CDCs, and promotes the intelligent transformation of water quality monitoring in the medical industry.
