Requirement
The university in Hong Kong required a reliable and automated control infrastructure for its sewage treatment system. The objective was to manage multiple treatment stages—such as filtration, sedimentation, and other wastewater processes—through stable, centralized control while ensuring high compatibility, operational safety, and long‑term system reliability.
Solution
Geya provided a customized automation control cabinet solution to meet the facility’s process control needs:
- Component Integration: Each control cabinet is equipped with MCBs, fuses, timer relays, general relays, contactors, thermal relays, transformers, and other essential protection and control devices.
- Centralized PLC Control: All relays within the cabinets are managed by a unified PLC system, enabling precise coordination of different sewage treatment processes and ensuring smooth operation across filtration, sedimentation, and subsequent stages.
- Relay Compatibility: The relays supplied by Geya Electric feature standard GEYA models that are fully compatible with mainstream brands, ensuring seamless interoperability and reducing maintenance complexity.
