Phenol analysis for water

Online phenol analysis to support treatment investigations and industrial effluent monitoring.

Watch for changing phenol levels in industrial wastewater

Industrial wastewater can vary with the process that produces it. A 3S phenol analyser provides repeated measurements at a selected sample point, giving the team a trend to compare with production conditions and reference samples.

Discuss the compounds present, the reporting method and the expected range. The response of this method should not be assumed to identify or quantify every individual phenolic compound.

Where the measurement is useful

Industrial effluent

Follow concentration changes through the operating day and investigate unusual readings.

Treatment assessment

Compare inlet or outlet trends with laboratory analysis and treatment settings.

Variable process streams

Review peak concentrations and sample preparation, including whether a dilution option is appropriate.

How the measurement works

The colourimetric method uses a 4-aminoantipyrine reaction to produce a coloured complex. Its absorbance is measured against the calibration for the selected phenol method.

The 3S-CL runs batch analyses at a programmable frequency. Automatic calibration, validation and cleaning can be scheduled, and the analyser separates its wet section from the electronics.

Agree the required range, cycle time and plant outputs when specifying the instrument. The manufacturer documentation gives the options and installation requirements for the selected configuration.

Plan the installation around the sample

Send PMA the sample source, expected concentrations and available laboratory results. Include temperature, pressure, solids and any constituents that may affect the analysis.

We will review sample delivery, filtration or dilution where needed, drainage, reagent storage and service access. Include the required signals and alarm response so the measurement can be used by your operating team.

A question worth asking

Will it identify individual phenolic compounds?

This is a colourimetric measurement for the configured phenol method. It is not a compound-separation technique. If you need individual compound identification, discuss the required reference analysis alongside online monitoring.

Let’s talk about your application.

Speak to the PMA team about your instruments, reagents or service requirements. Tell us what you need, and we’ll help you find the right next step.

  • Advice for your application. Find the right instruments, sensors and chemical reagents for your process.
