HRSD Optimizes Wastewater Purification With Unisense Environment N2O Sensor

HRSD, the regional wastewater treatment utility that serves southeast Virginia, works in cooperation with a number of utilities to test new purification processes in pilot and full scale wastewater treatment plants. One focus is on application of the deammonification process which includes monitoring dissolved N2O online with a sensor from Unisense Environment.

“HRSD is a frontrunner in new ways to purify wastewater. They have been using our equipment for research but have recently implemented the N2O Wastewater System into their pilot scale production,” Mikkel Holmen Andersen, PhD and Director of Wastewater Business at Unisense Environment, says. He continues:

“Monitoring N2O levels with our sensor system provides HRSD with new information on top of levels of oxygen, ammonium and nitrite – a parameter that was not available to them previously.”

Deammonification Control
Deammonification is central to wastewater purification. The system from Unisense Environment, which is the first in the world, provides data used for optimizing the purification process to make it more efficient and environmentally friendly.

“When working with deammonification, you control the flow of air and the amount of nitrite, which are two key parameters in the purification process. By monitoring N2O, you get results that show the coupling with both oxygen and nitrite levels, and this opens possibilities to control them better,” Mikkel Holmen Andersen says.

Unisense Environment will be exhibiting at WEFTEC in Chicago. Meet them at the Danish Pavilion Hall B, booth 2688.
