Bio Facility Upgrade
Kenton, Ohio
Project: Bio Facility Upgrade
Features: Control System Upgrade
Summary of Scope of Service
ATSI provided engineering services to evaluate and upgrade the Waste Water Bio Facility operations. The goal of this project was to improve current operations by improving system information, and eliminate the need for weekend operators. The control system consisted of a Modicon 984 PLC with WonderWare Intouch used for the operator interface.
The Modicon 984 PLC was replaced with a Quantum PLC to allow Ethernet communications, and a Modicon Momentum PLC system was added with wireless Ethernet communications for the monitoring of remote storage tanks. Control system improvements were made in the areas of sand filter operation, polymer addition, and turbidity monitoring. WonderWare SCADAlarm was also added to the HMI system for remote alarm notification during unattended operation.
Services Provided
- Evaluated existing control system
- Revised existing P&I Diagrams
- Prepared all control wiring drawings
- Supplied equipment specifications for all new instrumentation
- Revised PLC and HMI programming
- Provided start-up assistance
