novoflow-SSDF: Single Shaft Disk Filter

The SSDF system is characterized by rotation of filter disks in the feed liquid and extraordinary low energy consumption of about 0,12W/1m² filter surface area.

Test plants are available in different sizes.

Deliverable plant sizes range from 1 m2 and 500 m2 filter area.

Optimal Applications:

• High concentration

• High levels of suspended solids.

• Viscous media

• Continuous concentration of recyclable fractions and active substances

• Emulsion separation

• Diafiltration (Washing solids out of liquids or vice versa)

Advantages and Special Properties:

• Energy savings of over 90 % vs. traditional cross-flow modules

• Compact and flexible modular design. Easy plant scalability, inspection and maintenance.

• Highly efficient overflow and cover layer prevention due to a special combination of centrifugal (rotation) and shear (turbulence created by baffles) forces.

• High rotation speeds of 500 r. p. m. and more with disk diameters of 312 – 500 mm.

• Trans membrane pressures are independent of over flow speeds and are equal over the entire filter area.

• Minimal foot print: max. 0,8 x 0,8 m2 per 1- 15 m2-plant

• Easy assembly and disassembly

• Automatic back-flushing

• CIP-compatible

Mode of Operation:

• A rotating membrane stack is mounted on a hollow shaft and placed inside the filter pressure vessel (module).

• Filtration is performed from the outside through the membranes to be collected inside the filter disks and eventually discharged via hollow shaft.
• The filter pressure vessel can be equipped with fixed or flexible baffles in order to create sufficient turbulences.
