Web based Diagnosis & Control System
- · We developed an We based package integrating modeling, diagnosis & control technologies. This system is able to operate a wastewater treatment plant as stable, economic, and optimized conditions for a long period of time. A demonstration was practised at a A2O pilot plant with 18 m3/d treatment capacity.
- · A statistical and mathematical model was developed and optimized for the subject plant. A control schedule for one hour intervals were made based on predetermined influent and effluent conditions. This schedule was applied for optimum operation following day and the effluent NH4-N concentration was obtained below 5 mg/L.
- · The process was controled based on effluent NH4-N cascade control and empirical NOX-N control. This practicse achieved 25% reduction of electricity cost and 50% reduction of external carbon cost.
- · A diagnosis system for process status was developed based on the PCA(Principle Component Analysis), the cluster analysis, and the discrimination analysis techniques.
- · A diagnosis system was developed to analyze the troubles of expensive equipments. Another diagnosis system was developed to analyze settling conditions of sludge in a settling tank using image analysis.
