About the Project
At the Porto de Sergipe thermoelectric power plant, Reditech developed the control software and commissioned the seawater intake system, which is responsible for desalinating and demineralising water by reverse osmosis for supply to the recovery boilers. The system consists of a set of seawater intake pumps, coagulation, flocculation and clarification tanks, mixed bed multimedia filters and a reverse osmosis unit.
Challenge
The project required a control system capable of:
- processing seawater continuously and safely
- managing all stages of coagulation, flocculation and clarification
- precisely controlling filtration and reverse osmosis
- ensuring reliable production of demineralised water for the boilers
- being fully tested, validated and commissioned
Our Contribution:
Control & Automation Software:
- Development of process logic for collection, coagulation, flocculation and clarification
- Automatic activation of pumps, valves and multimedia filters
- Complete control of the reverse osmosis unit
- Integration of all stages into a single reliable platform
Chemical Conditioning:
- Coagulant dosing logic
- Automatic flocculant dosing
- Clarification management with dynamic process control
Monitoring & Data Processing:
- Continuous monitoring of permeate, reject and clarified water flows
- Recording of quality and operating parameters
- Operational safety with alarms and interlocks
Commissioning & Startup:
- Testing and validation of the entire control system
- Adjustments to chemical dosages, filtration and reverse osmosis cycle
- System start-up and handover to plant operators
Results for the Port of Sergipe:
- Reliable production of demineralised water for boilers
- Optimised water treatment with stable quality
- Precise control of filtration, clarification and reverse osmosis stages
- Safe, validated and fully operational system
