IOT News

With industrial development and social progress, environmental protection has drawn increasing attention. As an essential part of industrial operations, wastewater treatment in coal preparation plants has also come into sharper focus. To better achieve environmental goals, improve treatment efficiency, and prevent accidents and losses caused by equipment failures, the adoption of IoT systems has become an industry-wide consensus.

Typically, wastewater from coal preparation plants undergoes multiple treatment stages—including grille screening, sedimentation tanks, and aeration tanks—before it meets discharge standards and is released. Throughout this process, the operating status and parameters of each piece of equipment must be strictly monitored—for example, the rotational speed of the grille machine, the dissolved oxygen concentration in the aeration tank, and the water level in the sedimentation tank. As such, data acquisition has become a critical component.

By connecting to water treatment equipment PLCs, sensors, cameras, and other devices, WideIOT industrial smart gateways collect and transmit data to enterprise IoT platforms (with support for 5G/4G wireless networks). This enables remote monitoring of parameters such as pressure, water level, flow rate, and water quality. Through the IoT platform, operators can gain intuitive visibility into on-site conditions and adjust equipment operating parameters in response to real-time conditions—thereby improving overall wastewater treatment performance.

System Functions
