The increased surface area boosts the filtration efficiency and results in a high throughput. For pharma/biotech applications, plastic components in contact with the process medium can be pre-sterilised, this making CIP/SIP redundant.
The filter bag is installed in a pressure vessel during filtration. This design opens up the possibility to compress the filter bag by applying an external pressure at the end of the batch, thus also allowing the filtration of the liquid heel. The unique design allows either a once through or a multi-cycle filtration, where the cake can be back-flushed and accumulated on the bottom of the bag. Finally the compressed bag containing the solid waste is removed and safely disposed of in a very compacted form.
