Description:
Upward flow of fluid through a bed of
particles is a naturally occuring phenomenon, for example the movement
of ground water. Industrial applications include ion-exchange,
extraction of soluble components from raw materials and other chemical
processes. The simutaneous study of air and water systems and the
phenomenon of ‘bubbling’ can be observed. The apparatus comprises three
clear acrylic columns mounted above a moulded ABS base. The base
contains a water reservoir with a variable speed submersible pump, which
pumps water through an electronic flow meter into the base of the left
hand column. This column features an overflow pipe, which returns the
water back into the sump. The two air columns are fed by variable
pressure regulators, which can be used to adjust the air flow rate
through the column. The air flow rate is measured using pressure sensors
at discharge orifices at the top of the columns. The integral micro
controller calculates the flow rates from the pressure readings and
displays these on the front panel
