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 variable speed 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 manometers 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, 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.
