— Wastewater & process water

Better process information from difficult water.

Spec-Imaging supports both continuous spectral process monitoring and portable colorimetric analysis in turbid wastewater and process-water streams. Choose the measurement approach based on what you need to know.

— Two measurement paths

Two ways to improve wastewater measurement.

Both IC-SPECTRO™ and IC-VIS™ use Spec-Imaging's scattering-aware optical approach to obtain useful measurements in samples where suspended particles interfere with conventional photometry. More on the technology →

Earlier visibility

See load and process changes between scheduled laboratory samples.

Treatment optimization

Use more frequent process information to support treatment decisions where validated.

Less dependence on grab sampling

Laboratory reference measurements can support calibration and validation instead of being the only source of process information.

— IC-VIS™ value

Colorimetric methods without letting turbidity dominate the result.

CONVENTIONALReagent creates color+Sample turbidity scatters lightMeasured absorbance can be biased
IC-VIS™Reagent creates color+Scattering information is measuredResult can be corrected for turbidity effects where validated

Instant Clarity™ reduces / compensates for scattering influence on the reading — it does not eliminate the need for a suitable method or matrix-appropriate validation.

What we can show today.

IC-SPECTRO™
ONGOING

Continuous monitoring at Castellet Bruk.

IC-SPECTRO™ is being installed for continuous full-spectrum UV-Vis monitoring of the wastewater process at Castellet Bruk — a real, ongoing project. Spec-Imaging is also developing wastewater-specific applications through a Vinnova-funded project with Lund University and NSVA.

IC-VIS™

Built on established reagent chemistry.

The IC-VIS™ Method Library already includes calibrated methods from established reagent-kit suppliers (Hach, Macherey-Nagel, Merck, Lovibond) covering wastewater-relevant parameters such as COD, nitrate, nitrite, ammonium, phosphate, chlorine and TOC — loaded onto the instrument by scanning a QR code.
