Liquid-Solid Separator
The Bioselect from Boerger is a closed loop, leak-proof screw press machine used for thickening or solid-liquid separation. When coupled with a Boerger Rotary Lobe Pump, material can flow into the Bioselect unit easily and without clogging.

Bioselect BS – Thickening Technology
The Bioselect BS is a combination of a separator unit with two rotary lobe pumps. Between these components, the feed pump conveys sufficient flow to the separator, while the discharge pump determines the level of thickening.
Advantages:
- Totally odorless operation
- Thickening rate is easily adjusted
- Feed pump discharges the separated liquid
- Turnkey, compact machine
- Closed-loop system allows for one machine to feed multiple tanks
- Wide range of flow and solid concentration

Bioselect RC – Dewatering Technology
The Bioselect RC unit, with Multi-Disc discharge, is available as a stand alone screw press separator. It is also available as a completely automated system with feed pump and control panel. The dewatering rate is controlled by adjusting the screw of the Multi-Disc spring assembly.
Advantages:
- Pumping of the separated liquid in a closed system is possible
- Rotating, spring loaded Multi-Disc ensures consistent, granular dewatered material
- Simple installation and cost-effective operation
- Rotary lobe pump can be connected to either the inlet flange or the liquid outlet flange
- Wide range of flow and solid concentration
