Nova Water Technologies

Nova Water Technologies LLC, based in Tampa, Florida, specializes in dynamic disk filter technology for tertiary wastewater treatment. Founded in 2006, the company developed the Nova Quantum Disk Filter, which employs a rotating AISI 316L stainless steel micronic screen with nominal 20-micron openings (effective down to 10 microns) to capture particles through progressive buildup at sub-90-degree approach angles. This tangential filtration mechanism eliminates the roller chains, sprockets, internal bushings, and bearings found in conventional designs, and the company reports a 75 percent reduction in gear drive power and 30 percent reduction in wash water volume and power compared to competing technologies. Backwash is triggered automatically when water level reaches a pre-set maximum, with solids conveyed by gravity to a reject trough — no external pumping required. The Quantum Disk Filter services flows up to 16 MGD and is suited for traveling bridge retrofits and concrete channel installations. In November 2009, the filter received conditional acceptance from the California Division of Drinking Water for Title 22 compliance, with loading rates not to exceed 6 gpm per sq ft at 4-log disinfection or 16 gpm per sq ft at 5-log disinfection. As of 2015, Xylem Treatment became the sole authorized supplier of the technology, now branded as the Leopold Ultrascreen Disk Filter. Nova Water Technologies reports over 50 Dynamic Disk Filter installations across the US and Canada.
