Driving Green Innovation: 

Smart Monitoring in Wastewater Management

Water is a vital natural resource facing escalating pressure from population growth and industrialization. Wastewater, laden with pollutants such as oils, suspended solids, and heavy metals, threatens both the environment and public health. Efficient wastewater treatment processes not only ensure the sustainable use of water resources but also provide a critical foundation for protecting the ecological environment.

Challenges Faced by Wastewater Treatment

  1. Management Difficulties:
    With extensive site and equipment distribution, immediate response to abnormalities is challenging.
  2. Complex Permissions:
    The increasing number of devices complicates operator permission management.
  3. System Incompatibility:
    Inconsistencies in data formats between new and legacy systems create difficulties in data interpretation.

Weintek’s Solutions

To facilitate integration with various brands and models of PLCs, Weintek's HMI offers exceptional communication capabilities, serving as the primary operation interface on-site. It aggregates data collected from the field and displays it on a large external screen in the control room, enabling centralized monitoring of the entire facility.

  1. Data Visualization – Graphic Objects and Picture Libraries
    The HMI collects on-site data and aggregates it in the control room, displaying this information on large screens using dynamic objects, trend charts, and a high-quality picture library to accurately reflect on-site conditions and enhance monitoring efficiency.
  2. Authorization Management and System Security – User Security and Operation Log
    Dashboard features user authorization management and an operation log, ensuring full traceability of actions and operator safety.
  3. Real-time Notification and Remote Monitoring – EasyAccess 2.0
    EasyAccess 2.0 offers a remote connectivity service that sends push notifications to personnel about data anomalies. Pass-through functionality allows maintenance staff to connect remotely to the PLC from the HMI for tuning and troubleshooting.
  4. Data Output and Management – FTP Client/Server Two-way File Transfer
    In addition to external USB backups, the system supports bidirectional FTP access for reports and screenshots. HMI data is output in a universal format for easy retrieval and long-term storage.

Outcomes and Benefits
