Micro-pollutant removal system for wastewater
Higher cyclone capacity within existing footprint
Xylem’s Leopold Oxelia ozoneenhanced biologically active filtration system is a multi-barrier solution to effectively eliminate micropollutants in secondary treated wastewater and to provide an efficient organics elimination step to enable Indirect Potable Reuse schemes in water scarce areas.
Weir Minerals reports that its new Cavex 700CVX hydrocyclone can achieve up to 50% higher throughput capacity in comparison with any other competitor cyclones in the 26 in diameter range due to its larger inlet and vortex finder configuration. The Cavex 700CVX hydrocyclone also provides a higher throughput than the Cavex 650CVX hydrocyclone, in a smaller body, making it suitable for new installations. It is also suited and sized to fit into existing cyclone clusters.
The solution consists of an ozone system followed by a biological active filtration system. The process steps are matched and controlled by a dedicated set of online

analysers using ultraviolet Vis Spectrometry that feed into an integrated control system to help optimise operations. The Oxelia system uses the power of ozone to break down non-biodegradable organic trace contaminants (TrOCs) such as pharmaceuticals and personal care products that can pass through conventional systems almost untreated. It also disinfects and eliminates tastes and odors. The biological active filter eliminates any organic byproducts and removes organics completely. The biofilter guarantees low suspended solids concentrations and polishes off remaining nutrient concentration without the generation of concentrates. www.xylem.com/treatment
Cavex hydrocyclones are designed to withstand severe abrasion caused by the rotational flow of solids and slurry. The shape of the range features a laminar spiral inlet geometry that allows the slurry to follow a natural path without encountering any shelves, edges or corners. This reduces turbulence inside the hydrocyclone which helps maximise separation efficiency,

hydraulic capacity and wear life, while minimising localised wear in the feed chamber and vortex finder. Other features include fabricated steel or cast ductile casing, replaceable elastomer liners up to 45mm thick, ceramic lower cones, rubber lined steel vortex finders, rubber or ceramic spigots, rubber lined steel overflow pipe or air core booster caps. www.weirminerals.com
