Heavy loaded and changing sample matrices make online measurements difficult. SEIBOLD Wasser developed a process to test online Measurements in tricky sample situations.
In many industrial waste water applications many different processes deliver it’s waste water to the treatment station.
- What makes online measurements complex:
- Heavy loaded sample matrix. Strong interfering ions.
- Solvents and oxidation/reduction agents.
- Fast changing sample matrix.
- Sample colour.
- Sample turbidity.
- Buffered extreme pH levels.
- Measurement principles.
- SEIBOLD COMPOSER online analyser measure with spectrophotometric technology.
- The measurement is light absorption at specific wave length introduced by a coloured complex.
- The couloured complex is build by a heavy metal and the reagents.
- The reagents are a buffer (pH-level adjustment, catalysts, surfactants, oxidizing agents and masking agents) and the dye for colour complex creation.
- All reagents are developed specific for online measurement purposes by SEIBOLD Wasser.
- These proprietary reagents can be adopted to specific needs for more accurate measurement results.
- Feasibility Study Procedure:
- We get a full sample analysis from the client. Based on our experiences we can estimate the difficulties of sample measurements.
- We get real samples and measure them before and after reagent adjustments.
- We install a test analyser at client site to measure the sample for 3 month.
- Every month we visit the site and discuss results and procedures to optimise the measurements.
- We produce a report about measurement quality, alternative operations and appropriate measurement technologies .
