Product catalog summary

Overview of Rotation Filtration with Ceramic Filter Discs
Rotation Filtration, also known as Dynamic Cross Flow Filtration, is a technique that utilizes ceramic filter discs to achieve maximum filter efficiency. This method is characterized by extreme cross flow velocity, which ensures efficient cleaning of the filter surface with very low energy consumption compared to conventional techniques. The cross flow effect is generated by the rotation of the filter discs rather than by pumping large volumes, enhancing process safety.

Advantages of Ceramic Filter Discs
Ceramic filter discs are available in sizes of 374 mm, 312 mm, and 152 mm, suitable for microfiltration and ultrafiltration. They offer resistance to chemical and thermal stresses, high filtration flux, and long service life. These discs can be regenerated through backflushing or hot steam sterilization and are designed for optimal integration into plant engineering.

Test Filtration Plants for Engineering
Kerafol provides parameters for the installation of ceramic filter discs in filtration units, making them an excellent choice for project planning of large filtration units. The company offers rental options for dynamic cross flow filtration modules with a membrane surface of 35 m².

Technical Specifications
The ceramic filter discs have specific dimensions and membrane surfaces, with the largest being 374 mm in diameter and offering a membrane surface of 0.20 m². They are designed to filter from outside to inside, supported by a pore size of 2.0 µm, and coated with layers for micro and ultrafiltration.

Applications
Kerafol ceramic membranes are used across various industries, including wastewater treatment, food technology, pharmaceuticals, biotechnology, chemical industry, digester effluents, and oil and gas. They are suitable for all areas of solid/liquid filtration.

Contact Information
For inquiries, Kerafol can be contacted at their headquarters in Eschenbach, Germany, via phone or email. They offer a broad range of products with diverse application possibilities.

Rotation Filtration with Ceramic Filter Discs Why Rotation Filtration? ▪ Extreme cross flow velocity (High efficient cleaning of the filter surface) ▪ Very low energy consumption (Compared to conventional cross flow techniques) Maximum filter efficiency Rotation Filtration (Dynamic Cross Flow Filtration) ▪ The cross flow effect (tangentially flow cleaning of the filter surface ) is generated by the rotating of the filter discs and not by pumping of large volumes. Why Ceramic Filter Discs? ▪ Resistance to chemical and thermal stresses ▪ High filtration flux and very long service life ▪ Regeneration...

Dynamic Cross Flow Filtration Diagramm of a Rotation Filtration Plant Rotating Ceramic Filter Discs are assembled in a pressurised housing. The design of the discs shows drainage channels in the inside. The filtrate is transported from the outside to the inside of the discs. The rotation of the discs generates shear forces on the membrane surface. With this technique an increase of a filter cake is avoided resulting in a high filtration flux. Ceramic Filter Disc Main Parameters ▪ Rotation Speed (rotating Ceramic Filter Discs) ▪ Transmembrane Pressure TMP (pressurised housing) ▪ Solid Content...
