3 variants of the WTW drinking water panel: With different numbers of flow cells and with or without turbidity analyzer
Smart signal processing – the sensor has a special pattern detection feature and can therefore distinguish between the sludge level and undesired signals.
Nitrogen elimination – transparent, process optimized, economical. Nitrate measurement directly in the medium – optimized for regulation purposes
Spectral UV-VIS sensor to measure color in wastewater, incl. integrated ultrasonic cleaning; available wavelengths (selectable): 340 nm, 350 nm, 390 nm, 410 nm, 445 nm, 455 nm, 465 nm; including turbidity compensation
