Model SCF Flatbed Air Vacuum Filter
In numerous solution clarification applications involving moderate to high flowrates, the Filtertech Model SCF flatbed vacuum filter provides the desired clarity by removing even the finest particles using a wide range of filter medias. To achieve the very high flowrates through the filter, a vacuum producer is used to increase the filtration rate.
The Filtertech Model SCF flatbed vacuum filter is available in a variety of configurations and sizes to meet your specific requirements.

Mode of Operation
Dirty liquid is fed into the filter through a low velocity inlet distributor. As the air is evacuated beneath the filter bed, a pressure differential across the media is created. The contaminants are intercepted to form a cake which then becomes the filter media. As the cake becomes thicker and less permeable, a pool is formed in the bed of the filter. Over time, the level control float which energizes the conveyor drive system introduces a small section of fresh media at one end and discharges the contaminants and spent media at the other end of the filter. These contaminants are exposed to the drying action of the extraction chamber which shears the loose liquid from the cake, returning it to the system and minimizing makeup requirements. This also yields a drier contaminant for easier disposal. The clean liquid entering the vacuum chamber gravity flows through the clean outlet to a separate clean tank for delivery back to the process. During the incremental indexing of the media, flow from the filter is not interrupted.
