The increased surface area boosts the filtration efficiency and results in high throughput. For pharma/biotech applications, plastic components in contact with the process medium can be pre-sterilised, 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 filtration of the liquid heel.
The unique FUNDABAC® SU 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 compact form.
The unique CONTIBAC® SU design builds up on the FUNDABAC® SU with the same features. However, it additionally incorporates a discharge opening to allow accumulated solids to be back-flushed with water or any other liquid. After discharge the filter can be put back online. This significantly extends the life time of the filter bag and reduces operating cost.
