Modular Cross Flow Filtration

The system uses a high-pressure piston-recirculation pump to circulate product through the filter module of choice.

The triple-piston design combined with high-pressure flexibles minimises pressure pulsation. The operator can use their own feed vessel or this can be specified. The speed of the recirculation pump can be adjusted to suit the particular filtration module and the product. The retentate back-pressure valve enables pressures up to 50 bar to be achieved. Accidental system over-pressure is avoided by a bursting disc downstream of the recirculation pump.

Features:

1. Capable of microfiltration, ultrafiltration, nanofiltration and revese osmosis operations
2. Maximum filtration pressure of 50 bar
3. Clean-in-place capability
4. Backpulsing option (suitable for certain modules)
5. Variable retentate flow rate in order to change filtration cross-flow velocity
6. Retentate electronic flowmeter measurement
7. Retentate and permeate back pressure valves
8. Pressure sensors on the retentate inlet and outlet of the filtration module and on the permeate line
9. Mass balance option for permeate flow rate measurement
10. All parameters are data logged
