Application
Flow Sieve DF BV/DV is a device used for separation of biological reactor suspended bed blocks. Solid, faultless structure and simple maintenance make this device almost self-operating.

Functioning
The wastewater flows perpendicularly to the semi-round sieve, which holds the suspended bed blocks. The filtered fluid flows to further stage of biological treatment and blocks remain in the reactor chamber. The perforated surface is constantly cleaned preserving the device hydraulic capacity. The controlled cleaning system is driven with motoreducer secured against weather conditions. Guides system enables easy and quick disassembly of the sweeper. The device is assembled on reactor wall in manner stopping the blocks from getting outside the tank.

Equipment
- Perforated filtering part of clearance adjusted to the suspended bed blocks
- Automatic cleaning-sweeping system.
- Supporting structure equipped with guides enabling  easy and quick disassembly of the sweeper. Motoreducer secured against weather conditions.
- Ex version [option].
- Winter package enabling outdoor installation of the device, system operated through signals from two autonomic thermostats (as an option).
- Material: stainless steel. Other materials may be used on demand.

Product features
- Biological reactor suspended bed blocks separation system
- Adjustable cleaning-sweeping system
- Low investment and maintenance costs.
