Application Note: Water Intelligence System Reduces Phosphorus Levels and Improves Denitrification
A wastewater treatment plant in Hassen, Germany needed to improve its denitrification processes. At the same time, there was an opportunity to qualify for a fee reduction/ waiver from the government if phosphorus levels could be dropped by at least 20%.
A Hach® Real Time Control (RTC) system was installed, including a Phosphax sc unit, a Solitax sc unit, two LDO Model 2 oxygen sensors and two AN-ISE probes (for NH4 and NO3) as well as a Claros-Enabled RTC interface and Prognosys predictive diagnostics for instrument maintenance.
Immediate and major improvements were made in a variety of metrics, notably phosphorus outlet (-45% year-to-year), Ntot outlet (-64% year-to-year), and energy consumption (-66% year-to-year).The plant also qualified for the fee reduction/ waiver for lowering phosphorus.
