NK Engineering’s automated wastewater monitoring solution complies with Circular 10/2021/TT-BTNMT and Decree 08/2022/ND-CP, providing continuous real-time monitoring of pH, COD, TSS, Ammonia, and flow rate parameters to ensure environmental compliance.
Overview of the Wastewater Monitoring Solution
In the context of increasingly stringent environmental protection regulations, manufacturing enterprises with large wastewater discharge volumes are required to implement automated and continuous wastewater monitoring systems.
According to Decree 08/2022/ND-CP, facilities with high discharge volumes or classified as high-risk must install automated monitoring stations that transmit data directly to environmental management authorities. Simultaneously, Circular 10/2021/TT-BTNMT sets technical standards for wastewater monitoring, mandating key parameters such as pH, TSS, COD, ammonia, and flow rate, along with strict data storage and transmission requirements.
Understanding this urgent need, NK Engineering has developed an Automated and Continuous Wastewater Monitoring Solution based on advanced technology from Endress+Hauser, enabling real-time control of discharge quality while ensuring data transmission compliance with the Ministry of Natural Resources and Environment standards.
Outstanding Values and Benefits:
Regulatory Compliance: The system is designed to meet the requirements of Circular 10/2021/TT-BTNMT and Decree 08/2022/ND-CP, helping enterprises fulfill legal obligations for environmental monitoring.
Continuous Real-Time Monitoring: Monitoring data is recorded automatically 24/7, enabling early detection of anomalies and timely alerts for environmental standard violations.
Data Transparency & Reporting: Monitoring data is transmitted directly to the Department of Natural Resources and Environment and to NK Engineering’s internal monitoring software, facilitating easy historical data access, report generation, and remote supervision.
Easy Maintenance: Devices utilize Memosens technology allowing quick calibration, ensuring high accuracy and minimizing operating costs.
Flexible Parameter Expansion: The system can be easily upgraded and expanded to measure additional parameters as required.
Automated Wastewater Monitoring System
Core Components of the Monitoring System:
NK Engineering’s automated wastewater monitoring solution is a fully integrated system comprising four main components:
1. Wastewater Monitoring Station
Flexible design: containerized, stainless steel cabinet, or fixed station tailored to each plant’s requirements.
Fully equipped with operational infrastructure: air conditioning, fire and smoke alarms, surveillance cameras, lighting, and safety systems.
Ensures stable environmental conditions for analytical equipment to operate accurately and reliably.
2. Automated Measurement and Analysis System
The primary measurement devices used in the monitoring system are highly reliable instruments supplied by Endress+Hauser.
pH sensor – Memosens CPF81E (with integrated temperature sensor)
Turbidity sensor – Turbimax CUS51D
COD sensor – Viomax CAS51D
Ammonium sensor – ISEmax CAS40D
Multi-channel signal transmitter – Liquiline CM44x
Depending on specific requirements, the system can be further integrated with:
Total Nitrogen analyzer – CA80TN Analyzer
Total Phosphorus analyzer – CA80TP Analyzer
Other parameters as requested
For real-time monitoring of discharge flow rate:
Electromagnetic flowmeter Promag W 400: measures influent wastewater flow through pipelines
Ultrasonic flowmeters Prosonic FMU90 & FDU90: measure effluent wastewater flow in open channels
Automatic sampling system Liquistation CSF48: Upon detection of any parameter exceeding thresholds, the sampler automatically collects samples into containers and maintains them at 4°C as per regulations.
Automated Monitoring and Measurement Instruments
3. Control and Data Transmission System
Central PLC Control Cabinet: Coordinates all operations of the monitoring station.
Beckhoff Data Logger: Collects, stores, and transmits data directly to the Department of Natural Resources and Environment’s portal in compliance with regulations.
Central Monitoring Software: NK Engineering deploys internal monitoring software with a web server interface. Monitoring data is visualized in real-time charts, providing timely alerts for any parameter violations.
