The Fixed and Fluidised Bed Unit, "LFF", allows a full study about everything concerning the flow of a fluid through a particles bed, both fixed and fluidised.
The unit is composed of two transparent removable columns for the simultaneous study of the air and water flow through the bed.
In the Fixed and Fluidised Bed Unit, "LFF", each column is connected to a manometers panel, which indicates at all times the pressure drop caused by the bed.
Water is pumped from a tank, located at the back side of the unit, to the bottom of the first column, passing through a flow control valve and a flow meter.
Air is supplied to the second column through a compressor located at the back of the unit. The air flow is measured by a flow meter.
There are glass beads of two different sizes for the bed.
