Tracer™

Removable compounds

The Tracer™ MBBR process removes harmful compounds

Industrial effluents can often be loaded with special and complex compounds. Some of these compounds are difficult to remove and can also be harmful to the environment and living organisms if left untreated.

AnoxKaldnes Tracer™ technology successfully removes compounds like glycols, cyanides, and selenium in several applications.

Glycols

Glycols are used in applications with a focus on antifreeze and de-icing agents and solvents. They are industrially produced in large amounts worldwide and they tend to reach wastewater treatment plants if captured in sewage or industrial wastewaters.

The biodegradability of these compounds depends on the types, their concentrations and loads, and the adaptability of the microorganisms in the treatment plant.

Cyanides

Although naturally present, cyanides can be toxic and affect all living organisms, including microorganisms in biological treatment processes.

Cyanides play a key role in different industrial processes and products. Cyanide-containing wastes are typically generated from industries that manufacture paints, polymers, organic compounds, and pharmaceuticals, or steel and coal production.

Selenium

Selenium is an essential nutrient for all living organisms; humans need approximately 10-50 ppb (µg/L) daily. Nevertheless, selenium compounds bioaccumulate in aquatic environments, and even at low concentrations can compromise the health of living organisms. Discharge into the environment is becoming an increasing concern.

Selenium-contaminated wastewaters are generated by industries in coal and mineral mining, coal-based power generation, oil extraction, and petrochemical refining, metallurgy, and agricultural irrigation. Effluents from the production of solar panels and lithium batteries also tend to be contaminated with selenium.
