Nova Water Technologies provides Dynamic Disk Filters which provide advanced dynamic tangential filtration for tertiary treatment of secondary effluent. The Nova Quantum Disk Filter can service up to 16 MGD for travelling bridge retrofits or concrete channel applications. The rotating SST mesh is affixed to a slowly rotating disk that provides dynamic filtration because particles approach at less than 90-degree angles. This allows for particles that are less than the size of the mesh openings to be captured and retained by the mesh. The progressive capture/ retention of suspended solids increases the water level in the filter until it hits a pre-set maximum fill set point. At this time, the backwash is automatically triggered and solids are washed away from the mesh into reject trough via gravity flow.
