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. On the discharge

side, a counter bearing stabilizes the smooth run of the auger. This way, the longest

possible service life can be achieved with extremely low wear. 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. 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) directly and until

the required dry content 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.

DURABLE TWO-FILTER SYSTEM

The filter system of the Bioselect is divided into two areas. In

drainage area 1, drainage takes place without pressure. Here,

a wedge wire screen with a high screening capacity is used (9).

In drainage area 2 (press channel), high pressure is produced.

In this area, a special wedge wire screen with 15 mm filter bars

is used (5).

The two-filter system ensures maximum efficiency and the

l ongest possible service life.

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 minimum space re-

quirements. The operator themselves can maintain the Bioselect.

Easily and quickly.

THE CONTROL TECHNOLOGY

Upon request, our in-house electrical engineering department

produces and programs a control technology which is perfectly

matched to your requirements.

• Ideal coordination of the operation of all components

(e.g. feed pump, macerator, liquid phase pump, Bioselect)

• Perfect utilization of the Bioselect, even with changing com-

position of the medium being fed, by a control that ensures

optimal loading (metered feeding); the results are a high

energy efficiency and wear reduction

• Production data acquisition (operating hours, flow rate, etc.)

• Protection of the entire system (pressure monitoring, dry run

protection, function monitoring, etc.)

• Integration e.g. to a biogas central computer via bus system

(Profinet, Profi- or Modbus, etc.)

• External control by operator possible via mobile communi-

cation, WLAN, DSL (remote support by Börger is also possible)

• Simple coupling with a PV system, effective use of own electricity

• Further functions tailored to the customer and project are

possible

+ Large capacities, low

energy consumption

+ Solid phase infinitely variable up to

a solid content of 38 %

+ No rubbing wear between the auger and

screen, extremely long service life

+ No risk of penetration − the rotating Multi

Disc is always leakproof due to its design

+ Four sizes with capacities of up to 150 m³/h

for each unit

+ «Everything from a single source»

− separator, pump, control unit

and service

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.

INSTALLATION OPTIONS

The installation options of the Bioselect are as versatile as their requirements.

Whether attached to a simple wall bracket, installed on a movable frame with

an upstream macerator or as a mobile raised hydraulically version or with a

conveyor belt – the application options of the Bioselect are unique.
