Utilizing the ADAM-3600 Edge Sensing Device-to-Cloud Solution to Build an Wastewater Monitoring System with Multi-Point Station Data Transmission
Advantech has built an edge computing IoT system from the ADAM-3600 intelligent remote terminal unit, which has WISE-PaaS/EdgeLink built in and is compatible with Azure Cloud Services. It accomplishes data collection, preprocessing, and transmission in one unit and integrates a cloud management platform that enables the installation of many continuous monitor systems with widespread measuring points and high-volume data management, thus allowing real-time the monitoring of discharged wastewater and ensuring compliance with public standards.
To prevent environmental pollution from industrial and domestic sewage, environmental conservation agencies of many national governments have established laws aimed at preventing water pollution in order to enforce control over wastewater discharge. As an example, for many years in Taiwan, factories and industrial parks have been required to install automated wastewater monitoring equipment once their daily wastewater discharge volume reaches a threshold, as per the Environmental Protection Administration (EPA), which is the country’s authority governing water pollution management. However, monitoring data might be subject to manipulation and fraud, and regular audits have proven insufficient for eliminating such wrongdoings. Moreover, with rising public awareness on environmental conservation, the EPA has further requested industrial and domestic sewage effluent water quality data to be linked online and posted in real time on the EPA’s public platform in order to protect the environment and ensure corporate responsibility. In addition, some governments at the county and city level have established defensive monitoring systems in local rivers to monitor water quality and thereby prevent malicious wastewater discharge from entering the river systems.
A Taiwanese system integrator who provides environment wastewater monitoring solutions was recently awarded an automated wastewater monitoring contract with a local government in northern Taiwan. The tender stated plans to monitor water quality in rivers and factory waste water effluents under jurisdiction, and this included volume, temperature, pH, conductivity, chemical oxygen demand, and suspended solids. According to the EPA’s requirements, data were to be transferred to the local environmental conservation authority’s monitoring center at specific intervals (chemical oxygen demand and suspended solids data were to be transferred once every hour, while the other monitor data were to be transferred every five minutes). The system also had to be linked to the EPA’s public platform in order to provide real-time data on water quality.
With only the ADAM-3600 intelligent RTU, which comes with WISE-PaaS/EdgeLink intelligent IoT technology built in, Advantech was able to meet the system requirements for continuous automated monitoring and cloud management. Water quality data are collected from various sensor brands at different measuring points and linked by the ADAM-3600, and then summarized, averaged, resized, or otherwise preprocessed through WISE-PaaS/EdgeLink. Finally, the processed key data are transmitted together via MQTT to the Azure cloud platform at the designated interval.
- ADAM-3600: Wireless intelligent RTU with 8 analog inputs, 8 digital inputs, 4 digital outputs, and 4-slot expansion
- WISE-PaaS/EdgeLink: Smart protocol conversion software
Advantech’s ADAM-3600 with WISE-PaaS/EdgeLink is a leading device in the field of environmental conservation and can satisfy the needs of environmental monitoring. System integrators may achieve device-to-cloud connectivity with simple settings on this compact RTU and shorten program development times. The RTU also handles many configurations of hardware products and thus simplifies maintenance work while the transfer resume feature ensures data accuracy and completeness. Multiple interface and modularization designs provide users with expansion options according to the intended application.
Further demonstrating the reliability of the ADAM-3600, but water utility companies in China have also adopted the same system structure as the one used this project to build domestic wastewater discharge monitor systems in villages in suburban Beijing, thus confirming the suitability of this unity in the field of environmental conservation monitoring.
