Wastewater sampler for effluent monitoring
Akzo Nobel Decorative Coatings are using an Aquamatic wastewater sampler to show they have reduced suspended solids and COD levels in treatment plant effluent from their site in Darwen, near Blackburn
Akzo Nobel Decorative Coatings, a leader in the development and manufacture of high performance coating systems, are using an Aquamatic wastewater sampler to help show that they have reduced suspended solids and COD levels at their site in Darwen, near Blackburn. The stationary sampler from Aquamatic, which has a proven, seven-year track record at Akzo Nobel, is used daily to take 24-hour composite wastewater samples from the recently upgraded site effluent treatment plant that handles wastewater from 22 emulsion paint tanks. Steve Lawrenson, Manufacturing Support Manager at Akzo Nobel, commented: ‘The Aquamatic sampler has proved very reliable and robust, helping us reduce our effluent charges as part of our overall water usage and environmental programme’.
He added: ‘We’ve never had any problems with the sampler, but have the peace of mind through an Aquamatic maintenance service contract that we are sampling to a very high standard and meeting the local discharge consent demanded by our water company’.
Situated outdoors at Akzo Nobel, the floor-mounted Aquamatic sampler incorporates a heater to provide frost protection for stored samples.

Sampler Removes bubbles for process analysers
The new ATM is an important accessory for any analytical instrumentation for on-line process analysis: it removes bubbles and enhances the accuracy and precision of process measurements
The new ATM is an important accessory for any analytical instrumentation that optically and/or chemically analyse liquids on-line in a process. It removes bubbles and enhances the accuracy and precision of process measurements. ATM enhances and increases the accuracy and precision of automatic measurements of turbidity, spectrophotometry, fluorescence spectroscopy and conductivity.
It works by sampling the process stream and temporarily isolating the sample in a separate chamber.
One of the key features of ATM is the removal of bubbles in the isolated liquid sample, this is critical to many on-line measurement processes since many measuring techniques are not able to distinguish between bubbles and particles.
Fluorescence and UV-Vis spectroscopy techniques for example rely on the integrity of a light beam passing through the sample, however bubbles can significantly effect this and give false readings by scattering the radiation.
Instruments developed specifically for analysis of on-line turbidity, spectrophotometry, fluorescence spectroscopy and conductivity, are only generally capable of generating accurate data from samples that are bubble free and immobile.
In addition, when using these techniques in coloured, foaming liquids, the results have often been an unknown combination of fouling on the sensor, colour of the liquid, turbidity and the scattered radiation caused by bubbles.
The ATM completely overcomes these very severe limitations.
Other important features of the ATM are.
* Elimination of false turbidity, spectrophotometry, fluorescence spectroscopy and conductivity measurements by removing all bubbles in the liquid before measuring: The sample is then reintegrated back into the process.
* Capability to make up to 200 measurements per hour.
* Full automation.
* Extremely reproducible measuring process each and every time, no risk of human errors.
* Full documentation of all measurements.
* ‘In process control’, therefore automatic control of pumps ,valves etc.
* Dramatic improvement in analytical operational margins.
* Heating and cooling of the sample is also possible if required.
