The Computer Controlled Filterability Index Unit, "PEIFC", uses 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 "PEIFC" 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 of a pipe.
The filter lower part is communicated with the flow sensor. A regulation valve located at the flow sensor 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 pressure sensor.
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.
This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
