2 Contract Details

2.1

Title

Supply & installation of a decanting centrifuge

2.2

Description of the goods or services required

The Wales Centre of Excellence for Anaerobic Digestion, based at the University of South Wales is seeking to procure a lab scale decanter centrifuge for continuous separation of solid and liquid phases in the output of a 100l scale bioreactor.

The decanter centrifuge will allow upgrading of our 100L scale anaerobic digesters to cope with high solids content wastes (Such as food waste, sewage, and crop residues) separating it into liquid and solids streams for advanced bioconversion into high value products. This will allow a greater applicability of USW research to 'real world' waste streams.

The unit must be able to fit in a 2m by 1m footprint, or as close as possible and must also be able to be controlled and ideally monitored via ananlog or simple TTL control signals sent and received by third party control hardware. The bioreactor contains materials with solids contents of at least 4%.

Must have a footprint of 2m x1m or as close as possible.

Must cope with a variety of feedstocks including wastewater sludges, food waste and some plant residues such as grass or straw.

Must be able to cope with incoming streams with at least 4% solids and preferably up to 12% solids or more.

Liquid and solid streams must be collectable on a continuous basis so they can be returned to the bioreactor automatically.

AC single phase power 240v power supply is preferred. Please detail any alternative power supply put forward.

Accessories

All accessories strictly necessary for correct installation and operation of the centrifuge should be supplied and included in the tender submission cost.
