Benefits of the PrimeFilter D
- Superior throughput – production increase per disc area of up to 20%
- Superior operation
- Less energy, less water needed
- Improved maintenance
With over 600 units in operation, the vacuum-assisted ANDRITZ DiscFilter is regarded as key equipment when it comes to handling most demanding thickening applications. A series of technical innovations have been incorporated into the new ANDRITZ PrimeFilter D to deliver superior throughput and operation with reduced energy costs:
The RotoWash is used for both, for deashing pulp and recovering fibers from filtrates and sludges. It also can be utilized as a protection filter for shower nozzles and alike. The machine design is based upon well-proven pressure screen technology.
The pulp filtrate of sludge suspension flows over a perforated plate with 100-300 µm holes with a high open area. The combination of basket and parabolic rotor creates optimum flow conditions. The fine basket perforations ensure superior fiber retention and boost filtrate quality.
