The IOA-PAG Conference brings together industry leaders to share the latest insights on the application and performance of ozone. The event will feature technical presentations from Xylem’s senior treatment engineers and product development specialists, as well as a showcase of Xylem’s advanced ozone technologies at Xylem’s booth #36.

Achim Ried, chief engineer with Xylem’s treatment business, will examine ‘Oxidation-enhanced biologically active filtration for drinking water’. Chemical and biological contamination in drinking water poses a significant public health risk and plant operators require a treatment system that allows them to produce a safe and reliable supply of clean water. Xylem’s Leopold Oxelia is a multi-barrier solution; an oxidation-enhanced, biologically active filtration system that enables the production of a safe and reliable supply of clear and biologically-stable, treated water with no taste or odor issues.

“Leopold Oxelia’s oxidation step can include ozone, ozone-based advanced oxidation processes (AOP) or ultraviolet (UV)-based AOP,” explained Ried. “The system offers the flexibility to efficiently and effectively address a wide range of treatment requirements, producing biologically stable and safe drinking water.”

Achim Ried will also present on Classic ozonation versus AOP for micropollutants in municipal wastewater for reuse applications’. This paper reviews several studies benchmarking the use of ozone, ozone with hydrogen peroxide (AOP) or UV-based AOPs for the treatment of secondary effluent to produce water that can be reused for irrigation purposes or in combination with membrane filtration for indirect or direct potable reuse. In addition to examining life-cycle costs and the treatment efficiency of these solutions, the presentation will also provide valuable insights on optimizing the efficiency of a reuse treatment train using ozone or AOP.

Xylem sales and application engineer for ozone, Wiebke Rand, will present a study entitled ‘A computational fluid dynamics (CFD) model for the estimation of ozone mass transfer in industrial scale reactors to support energy efficient reactor design’. The study aimed to develop a model capable of assessing the ozone mass transfer efficiency for drinking and wastewater applications in order to optimize the energy efficiency of ozone treatment processes.

Chemical and biological contamination in drinking water poses a significant public health risk and plant operators require a treatment system that allows them to produce a safe and reliable supply of clean water.

“Computational fluid dynamics is a state-of-the-art tool designed to monitor factors influencing mass transfer efficiency including: liquid and gas flow, ozone dose, water characteristics and water-specific ozone kinetics”, said Rand, “This presentation will review the results of CFD simulations carried out in pilot testing and detail how mass transfer performance can be predicted in order to inform the design and optimization of ozone contact tanks.”

Tony Zhang, product development with Xylem’s Leopold brand will present a paper entitled ‘Integrated ozone enhanced biofiltration system for municipal water reuse – Design & advanced system control considerations’. Wastewater reuse applications today look beyond non-potable usage treatment requirements to advanced treatment processes for direct and indirect potable reuse. The removal of micropollutants from wastewater using physical separation processes can be energy intensive however.

“This presentation will look at how an alternative treatment train incorporating ozone and biological activated filter (BAF) can significantly reduce capital and operating costs while effectively controlling effluent by-products,” explained Zhang.

A technical session exploring ozone and biofiltration applications will be moderated by Keel Robinson, North America water reuse leader at Xylem. The session will run from 2-5.15pm on Monday 29th August.
