Xylem introduces ozone-enhanced filtration system for wastewater treatment

American water technology firm Xylem has introduced a new ozone-enhanced biologically active filtration system and multi-barrier solution for municipal wastewater treatment.

Xylem’s new Leopold Oxelia uses ozone, filtration and analytical instrumentation for treatment of wastewater, which can be reused and discharged into sensitive waters.

It claimed to have the ability to treat and remove personal care products, active pharmaceutical ingredients and endocrine disrupting compounds in a water stream.

The Leopold Oxelia can be used in municipal wastewater tertiary applications of more than one million gallons per day.

It requires lower capital costs when compared with reverse osmosis-based membrane solutions and does not produce another waste stream requiring further treatment.

Xylem product manager Anton Callery said: "Xylem’s Leopold Oxelia ozone-enhanced biologically active filtration system harnesses the power of ozone to break down organic carbon compounds and pathogens.

"Microbes in the filtration system biologically use these smaller, partly oxidised organics for food, resulting in complete biodegradation.

"Unlike other treatment systems, the compounds are not just concentrated in another waste stream; they are destroyed.

"Recently tightened regulations, such as in Switzerland, will require the implementation of advanced treatment systems to minimise the quantity of trace organic contaminants (TOrCs) entering the water system and to protect sensitive water bodies as drinking water resources.

"This solution from Xylem can be used to upgrade existing wastewater treatment plants to meet new regulations."
