Benefits
The S2 Agitated Nutsche Filter (ANF) is engineered to offer exceptional performance and flexibility in filtration processes. Its unique agitator design, which operates through movements both parallel and perpendicular to the shaft, sets it apart from conventional systems. Here are the key benefits of the S2 ANF solution:
- Enhanced Fluidisation: The agitator ensures that slurry contents remain fluidised, allowing for efficient filtration of the mother liquor. This dynamic agitation helps to maintain optimal flow and processing conditions throughout the operation.
- Automated Cake Washing: The ANF features an integrated automated production cycle that allows for washing of the cake within the vessel. By reslurrying the cake after filtration, the system ensures thorough washing and efficient removal of impurities. The mother liquor can be refiltered post-washing to maximise recovery.
- Efficient Cake Discharge: The agitator can be lowered and rotated to direct the cake towards the discharge port, minimising waste and optimizing the discharge process. This innovative design reduces the amount of residual cake, enhancing overall process efficiency.
- Versatility and Automation: The S2 ANF excels in versatility, offering comprehensive solutions for filtration, washing, and reslurring with complete automation. This automation not only streamlines operations but also reduces manual intervention, improving process consistency and reliability.
- Improved Maintenance: The optional detachable portable filter unit facilitates easier access for maintenance and replacement. This design feature simplifies upkeep and ensures that the filter system remains in peak operating condition.
- Optimal Chemical Compatibility: The use of FEP elastomer sealing ensures excellent chemical compatibility, making the S2 ANF ideal for handling a wide range of solvents and potent substances in plant batch operations.
The S2 ANF solution delivers robust performance and flexibility, making it a valuable addition to any filtration process, particularly in environments where operator safety and process efficiency are top priorities.
