OPUS (aero) in biological waste water treatment

TriOS OPUS and OPUS (aero) are powerful spectral probes for the online measurement of Nitrate and Nitrite in aeration tanks.

Biological wastewater treatment serves to break down excess nutrients such as nitrogen, carbon and phosphorus with the help of micro- organisms (activated sludge), thereby protecting water bodies from pollution. The nitrogen contained in the wastewater is eliminated in a multi-stage process.
OPUS (aero) offers an easy-to- implement, reliable and purely optical online solution.
