The Hydroflux HyBAND® is a high efficiency, centre flow band screen used in the headworks of a sewage treatment plant.
High efficiency fine screening from a sewage treatment plant’s inlet significantly reduces maintenance costs from blockages due to screenings accumulation within the aeration and sludge processing plants.
- High efficiency screening – 80% Capture Ratio
- Reduced maintenance costs on downstream processes
- A compact design
- Self-tensioning band with no chains or submerged sprockets
- 20 years of sizing and design expertise specifically for Australian applications
HyBAND® Centre Flow Band Screen uses a continuous band of interlinked perforated panels that provide high efficiency two dimensional screening. Rags, fine screenings, plastics, bags and other foreign objects are captured on the panel face and removed from the sewage flow. The band also includes a series of serrated wipers to remove larger objects such as cans and small plastic bottles.
Hydroflux Epco provides complete inlet works systems, including screening removal and handling, grit removal and handling, as well as any associated conveying systems. We provide comprehensive technical analysis for hydraulics, headloss, screen control and solids conveying systems providing with a packaged solution to meet their needs.
A HyBAND Center Flow band Screen comprises the following features within one packaged plant:
- Highest screenings efficiency – double the efficiency of bar and step type screens
- A high flow capacity due to centre flow profile
- Fully automatic operation
- Self-tensioning band – increases the service life of the interlinked panels
- No chains as an interlinked panel system are used
- Panels are available in plastic or stainless steel and in a range of apertures
- No submerged sprockets or bearings
- Automatic bypass
- A standard size range to suit new and existing installations
Hy-Band® is a centre flow band screen used in the headworks of a municipal sewage treatment plant. The centre flow profile means a large surface area is presented to the influent, resulting in a higher flow capacity and lower headloss when compared to other screen types.
Hy-Band® provides a high level of screenings capture by using two dimensional panels, resulting in double the screenings captured compared to slotted or wedgewire type screens.
The band is a series of interlinked perforated panels (screens) driven by a head shaft and geared motor. The panels are fitted with end rollers which rotate within a track, eliminating the need for chain and submerged sprockets and bearings.
Head Shaft + Auto Tension Mechanism
The headshaft carries two driving sprockets and is supported by pillow block bearings on each end. A spring-loaded tensioning mechanism self-adjusts accommodating band stretch and to maintain the required driving tension.
The perforated panels are reverse cleaned via a spray bar system. The screenings are washed into a central launder and then discharged via a sluice to the downstream screenings handling system. The launder and sluice can be substituted with a spiral conveying system or compaction system to suit.
HyBAND® is available in four different inlet widths and with variable panel lengths to accommodate a wide range of flow rates, channel configurations and water levels. Capacities range from 50 through to 2500 L/s in a single screen.
HyBAND® is selected to ensure a velocity profile through the centre feed section, perforated panels and discharge result in a headloss between 200 and 500mm.
