TFUC Unité de Filtration Continue et Discontinue, Contrôlée par Ordinateur (PC)

This filtration unit has been designed to study the filtration process with two different types of filters. On one hand, there is a vertical plate filter consisting of nylon plates with a diameter of 5 microns, used to filter a known concentration CaCO3 suspension. On the other hand, there is a cartridge filter, more suitable for continuous filtration of larger size materials. It will be used to filter and "clean" a water sample with small pieces of paper.

To carry out the experiments, the mixture will be taken from a tank by a computer controlled centrifugal pump and send to one of the filters depending on the position of the valves. A motor driven stirrer will make the sample inside the tank more homogeneous.

Along its way, the mixture goes through two pressure sensors and a flow sensor, which will help us to determine the flow through the circuit. The initial temperature of the sample can be controlled by a heating element and a temperature sensor (PID Control), which will provide the temperature value at any time.

There are two operation modes with the unit: the filtered product can be sent to the initial tank to be filtered again or to a "product tank" to be analyzed after passing through the filters only once. Besides, the unit can work at constant flow and at constant temperature.

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.
