Chemical - free measurement: COD, NO3 and NO2 THE WTW SPECTRAL SENSOR

Innovative spectral measurement technique ... The optical method of the sensors enables a continuous measurement of carbon- and nitrogen-parameters directly in the medium. For simultaneous measurement of several parameters the information of the whole spectrum is evaluated during the process. At the same time cross-sensitivities of single parameters and interferences such as turbidity are eliminated. Easy handling • No sample taking and preparation • No reaction times • Minimal cleaning effort Minimal operational costs • No routine service necessary • No use of reagents • No spare parts...

... with the unique WTW ultrasonic cleaning system The integrated ultrasonic source induces oscillation of the measurement windows. The resulting movement of the surface prevents the attachment of dirt and fouling right from the start. This guarantees comparable and reliable measuring results during continuous operation. Cleaning effect of the WTW ultrasonic cleaning technology ... extremely resistant Robust materials such as Titanium and Peek down to the last screw Integrated shock protection Usage even in corrosive media High measuring accuracy • Continuous measurement directly in the...

• Influent measurement • Detection of influent peaks • Control/regulation of recirculation • Process optimization of the aeration • Effluent control *With the IQ Sensor Net several additional parameters can be measured -visit our website www.WTW.com/en/iqsn (For convenience use our QR code). UV-VIS sensors (200-720 nm) With these sensors C-parameters, Nitrate and optional TSS can be measured. • Nitrate • COD/TOC/DOC/BOD/SAC/UVT • TSS UV-sensors (200-390 nm) To distinguish between Nitrate and Nitrite these sensors with a higher resolution are required. • Nitrate • Nitrite •...

The spectral sensors at a glance: CarboVis: for Systems 2020 and 282/284 Measuring parameters: COD/TOC/DOC/ BOD/SAC/UVT, optional TSS Measuring parameters: Nitrate, Nitrite Measuring parameters: Nitrate, COD/ TOC/DOC/BOD/SAC/UVT, optional TSS Measuring parameters: Nitrate, Nitrite, COD/TOC/DOC/BOD/SAC/UVT 3 Effluent: Nitrate, Nitrite, COD/TOC/ DOC/BOD/SAC/UVT, TSS 2 Aeration: Nitrate, Nitrite, COD/DOC/SAC/UVT Influent: Nitrate, Nitrite, COD/TOC/ DOC/BOD/SAC/UVT, TSS In wastewater treatment plants increased Nitrite values can be a sign for an optimization demand of the biological processes....

* The quoted measuring ranges are theoretically possible. In practice, real measuring ranges exist that are given by the limits of photometric determination. The limits are significantly influenced by the light scattering due to solids and the absorption of accompanying substances (sample matrix).
