Xylem unveils new treatment system for potable reuse
09 June 2015, News release from Desalination & Water Reuse
Water technology company, Xylem, has unveiled a system for potable water reuse that harnesses chemical oxidation and biological treatment.
Xylem's Leopold Oxelia is a multi-barrier system that deploys ozone oxidation to break down organic carbon into material that can be digested by naturally occurring microbes that are attached to a fixed-bed filter. The aerobic biological treatment of the partially oxidized organic carbon leads to "complete destruction of total organic carbon, trace contaminants, and oxidation by-products" to produce "safe and reliable biologically-stable, treated water with no taste or odour issues," according to Xylem.
Oxelia incudes a centralized control system which "optimizes the biofilter operation based on ozone dosage and effluent water quality, optimizing the backwash sequencing and biological activity in real time" said the manufacturer.
Xylem showcased Oxelia at the American Water Works Association annual conference and exposition, ACE 15, held at tAnaheim, California, 7-10 June.
"Water reuse is a proven approach that can help meet growing water demands, producing high-quality water at a lower life-cycle cost than developing a new water supply. Water reuse delivers a resilient, drought-resistant water source with valuable economic and environmental benefits," the company said in a release.
Xylem was recognized recently by the WateReuse Research Foundation for its commitment to water reuse research and developing innovative water reuse solutions.
