Colour in Water & Wastewater I Water Quality Monitoring I Real Tech Water

WHY IS IT IMPORTANT?

For drinking water, colour is an important measurement for aesthetic purposes affecting the appearance and taste of the water. Colour in drinking water may result from coloured organic substances or natural metallic ions such as iron, manganese and copper. Colour causing organic substances are of particular concern due to their potential for disinfection by-product formation when they are combined with chlorine.

For industrial manufacturing, largely pulp and paper and textile industries, it is often measured in the wastewater for removal purposes and effluent monitoring. Dyes and coloured organic substances are used extensively to add colours to various different substrates in the manufacturing process. The wastewater stream from these processes can contain a high level of colors which, if discharged untreated, can cause environmental problems, problems for downstream drinking water facilities, or wastewater treatment issues for wastes discharged to the sewer system.

HOW WE MEASURE

Real Tech’s innovative multiple wavelength sensors utilize patent-pending and proprietary technology for superior measurement performance across multiple wavelengths of light using LEDs. Many compounds absorb light in the UV-VIS spectrum including color. Real Tech offers both bypass (CL series and MCL series) and probe (CA-X series and MCA-X series) Colour (ISO 6271-2016:05) and Multi-Colour (ISO 7887:2011 Method B) sensor options to allow the right selection for our clients needs. Multiple path length options are also available to ensure our clients have the detection range that meets their monitoring demands.

Real Tech has the solutions to help our clients get the information they need, when they need it. Discover our real-time monitoring solutions here.
