Question
Application Note: Precipitant savings through optimised phosphate elimination with integrated predictive diagnostics
Summary
A wastewater treatment plant was last modernised in 2007 and has the task of continuing to maintain the good condition of a river that was once significantly contaminated. The plant processes the wastewater of four connected communities.
Dosing of the precipitant was adjusted manually based on the laboratory measurement value of the daily composite sample and so was unable to respond to possible peaks.
 
Solution
A two-channel phosphate analyser with two sample preparation modules and the RTC-P control module for two dosing points was installed. The Prognosys predictive diagnosis system was then switched on to monitor measurement values.
 
Answer
Advantages
• Constant effluent values
• Optimised and lower precipitant consumption
• Monitoring of PO4-P values in the system
• Tool for checking the measuring instruments and the quality of the measurement values
