TB221018S05 Filterability Index Vocational Training Equipment Fluids Engineering Experiment Equipment
The Filterability Index is an unit for demonstrating the filtering process through a porous media. It enables a water quality test to be made on a suspension to be filtered through sand or similar granular media.
This unit utilises a bed of granular material, normally sand, which can be chosen by the student to suit his own purposes.The measurements taken with this unit enable a filterability index to be calculated which has significance in deep bed filter performance.
The Filterability Index unit is a bench-top unit composed of a feeding tank, where the initial solution of water with solids in suspension is placed. During the normal operation, the tank is communicated with the sand filter upper part, through a pipe of 10 mm diameter. The filter lower part is
communicated with the flowmeter. A regulation valve located at the flowmeter allows to change the flow which passes through the filter. The fluid pressure is obtained by means of the gravity, because the feeding tank is placed in high. The pressure is measured by a manometer.
The filter cartridge is easily removable, so it allows to study the difference between different media, both in compositions and in mesh.
This unit, in addition to students teaching and training, also can be used in routine control at water purification works, or at water treatment works which employ tertiary filtration.
Bench top unit.
Feeding tank of 1 litre capacity.
Filtration unit, with porous bed filter, removable:
Height of the filter: 70 mm.

The filter unit can be dismounted to change the sand.
A regulation valve controls the flow, which is observed on a flow meter.
Water flow meter, range: 0-550 cc/min.
Differential manometer of 500 mm, to measure the head loss.
Corrosion-resistant materials are used.
The elements and tubing connections of this unit are transparent so that the operation can be observed and air bubbles avoided.
