Automation in ETA’s and ETE’s is the use of technologies and systems to automate processes and tasks in thermoelectric plants (ETA) and water treatment plants (ETE). Automation can include process control, real-time monitoring, data analysis and equipment management to increase efficiency, reduce errors and ensure safety.

Operating Process

The automation operating processes in ETA (Water Treatment Station) and ETE (Sewage Treatment Station) include:

  1. Collection and transport: water or sewage is collected in collection networks and transported to the station.
  2. Physical treatment: removes solid particles through processes such as flocculation, sedimentation and filtration.
  3. Chemical treatment: use of chemical reagents to remove substances dissolved in water or sewage.
  4. Biological treatment: use of microorganisms to degrade organic matter in water or sewage.
  5. Disinfection: use of processes such as chlorination to kill microorganisms present in treated water.
  6. Storage and Distribution: Treated water is stored and distributed for public consumption or treated sewage is safely disposed of.


The benefits of automation in ETA and ETE include:

  • Greater efficiency: automation allows you to continuously optimize and monitor the treatment process, improving efficiency and reducing waste of resources.
  • Greater accuracy: automation provides accurate and constant data to adjust and optimize treatment processes.
  • Increased security: Automation allows continuous monitoring and rapid response in the event of failures or security issues.
  • Cost savings: Automation can reduce operating costs over time by improving efficiency and reducing the need for manpower.
  • Quality improvement: automation makes it possible to control and guarantee the quality of treated water or treated sewage.
  • Regulatory Compliance: Automation allows you to track and meet evolving regulatory requirements.


ETA and ETE automation applications include:

  • Process Control: Automation of control operations such as dosing chemical reagents, monitoring water or sewage quality, and controlling pumps.
  • Supervision: Continuous monitoring of water or sewage quality, including alarm detection and data analysis.
  • Energy management: optimizing the use of electrical energy, such as adjusting the speed of pumps and other equipment.
  • SCADA systems (Supervisory Control and Data Acquisition): remote monitoring of processes and equipment, including visualization of graphs and reports.
  • Quality control: guarantee of the quality of treated water or treated sewage through automation of process control.
  • Asset management: management and preventive maintenance of ETA or ETE equipment, including fault detection and performance analysis.
