Jul 04, 2010 · After pretreatment in a tumbling reactor, solid biomass is separated from the liquid in a screening device (Separation 1). A portion of fine solid particles is lost with the liquid stream. After Separation 1, biomass is washed in the same screening device to remove fermentation inhibitors remaining in the solid phase (Separation 2).

The method and systems efficiently extract recyclable materials from a mixed solid waste stream. The methods and systems use sizing, density and dimensional separation to produce intermediate waste streams that are enriched in particular recyclable materials. The recyclable materials can then be efficiently sorted from the individual intermediate streams using mechanized sorting equipment.

On solid bowl screen centrifuges used up until now the screening section is connected to the small diameter of the solid bowl cone and is dimensionally identical. This design arrangement has the disadvantage of offering a small volume and so a high solids capacity with reduced centrifugal force in precisely the dewatering section of the centrifuge.

On standard solid bowl screen centrifuges the screening section is connected to the small diameter of the solid bowl cone and the diameter of the screen is identical. This design has the disadvantage of a low volume in the dewatering section of the centrifuge. This leads to a high solids load and the lowest centrifugal force at the solid outlet.
