The Computer Controlled Plate and Frame Filter Press, "AFPMC", has been designed to studythe filtration and clarification processes using a filter press in which the number of frames andthe type of filter cloths can change.

A suspension is prepared in a feed tank and is transferred through a computer controlledcentrifugal pump into the plate and frame press. This pump ensures that the solids remainsuspended and do not settle.

The filter plates are grooved and covered over with filter cloths. Filter cloth (or filter media)retains the solid particles of the suspension, which fills the frame plates, whilst the filtratepasses through the filter media or filter cloth. The filtrate flows through the collecting pipe andis collected in the filtrate tank. The solid material is separated off from the filter cloth, whereit forms a growing filter cake. The unit includes several types of filter cloths.

The suspension passes through three pressure sensors and one flow sensor on its way. Besides, the initial temperature of the suspensionand the final temperature of the filtrate can be recorded with two temperature sensors.

A turbidity meter allows the solid concentration of the filtrate to be determined.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + aControl Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, forcontrolling the process and all parameters involved in the process.
