Hydroflux HyDAF-HDV Dissolved Air Flotation system

The Hydroflux HyDAF-HDV Dissolved Air Flotation (DAF) system has been specifically designed for applications where floatable suspended solids and FOG are combined with heavy solids or sand and grit which will rapidly fill and block a flat-bottomed DAF. It can also be used in applications where periodic emptying of the DAF to remove settled solids is impractical.

This V-bottomed DAF is designed with 60° sides and ends converging to a central screw conveyor mounted in the base where the heavier elements in the wastewater stream settle. The screw is designed to move the solids towards the drive end of the conveyor where either an actuated valve or pump is fitted to transfer the settled solids to the desired location.

The V series uses engineered external stuffing boxes to seal the bottom screw shaft which are tolerant of the potentially high grit application and simple to restuff without entry to the DAF tank.

The floatable FOG and light suspended solids are recovered in the DAF float which can be dewatered, composted or rendered subject to the application. The system can be operated with or without upstream chemical enhancement depending on the type of wastewater being treated and the performance required.
