The Börger Bioselect stands for efficient separation technology.

Using a purely mechanical process, liquid parts are separated

from solid parts in the medium.

PERFECT SEPARATION RESULT

BÖRGER BIOSELECT

OPERATING PRINCIPLE

The media to be separated find their way through the inlet opening (1) into the vessel-like

Bioselect. The outer cylinder is separated from the auger (3) by a roundly sealed wire-

wound screen (2) pipe. The auger has a frictional connection to the drive. The imported

liquid flows into the screen area next to the drive. The liquid flows through the wedge wire

screen (2) into the outer vessel area. The liquid drains through the liquid outlet (4).

The solid contents remain on the screen surface. They are conveyed into the press channel

(5) by the rotating auger (3). Powerful subsequent dewatering takes place in the press

channel (5). The rotating auger has a Multi Disc (6) (sealing disk), which can be shifted in

axial direction, at the non-drive end. The adjusting unit (7) presses the Multi Disc against

the auger and the compressed thick matter plug. When the thrust force of the plug is

greater than the spring force of the Easy Shift unit (7), a slot for discharging is created by

axial movement. A scraper edge is used to loosen and expel the solids.

MULTI DISC

Liquid penetration is impossible due to the Multi Disc techno-

logy (6). The Multi Disc (6) seals the press channel (5) as long

as the required drying stage of the thick matter plug is achieved.

This is when the slot for discharging opens and the solid phase

is loosened and expelled – penetration-proof technology.

EASY SHIFT TECHNOLOGY

The DS content can be varied continuously by

means of the Easy Shift (7) unit. Alternatively,

the DS content can be adapted fully automatically

(pneumatically) by means of a control unit.

AUGER WITH PROFILE GROOVE

Fibers are caught in the profile groove of the auger (3). The fibers

function as a sealing brush. Metallic rubbing between the auger

and the wedge wire screen (2) is avoided by the brush. This

unique technology increases the service life of the wedge wire

screen (2) and auger many times over. In addition, the brushing

surface cleans the wedge wire screen very thoroughly. Additional

cleaning by the operator is not necessary.

UNIQUE EASE OF MAINTENANCE

The Bioselect is maintained at the installation site without the

need to remove piping and the drive system. The auger (3)

can be removed from the drive shaft through the maintenance

opening (8) after a few screws have been loosened. This way,

the auger can be removed from the discharge side with mini-

mum space requirements. The operator themselves can main-

tain the Bioselect. Easily and quickly.

CONNECTION OPTIONS

The Bioselect can be operated very easily by means of the

control unit. The control unit coordinates the operation of the

feed pump and Bioselect perfectly. This way, the separator

is always operated at optimal capacity and achieves the best

possible results.

Alternatively, a liquid phase pump can convey the liquid phase

to where it is used next. An intermediate container is not required.

The Bioselect can also be fed by means of gravity feed from a

container. The control unit regulates the optimum load of the

separator by means of the liquid phase pump.

INSTALLATION OPTIONS

The installation options of the Bioselect are as versatile as their require-

ments. Whether attached to a simple wall bracket, installed on a movable

frame with an upstream macerator or as a mobile version with a conveyor

belt – the application options of the Bioselect are unique. Several separators

can be installed next to each other – also as mobile versions – for very high

separation quantities.

EXCELLENCE  MADE TO LAST

Thanks to its patented technology, the

sophisticated Bioselect is up to 25 %

more efficient than common separators

– energy-saving and low-maintenance.
