SF-DISC deep-bed filter modules
The SF-DISC module for deep-bed filters is made of filter cells, which in turn consist of two filter sheets. Two filter sheet blanks and a plastic drainage disc are joined together to form a filter cell. The edge of the filter cell is sealed by edge molding. Several filter cells are then assembled to form a filter module. The drainage is located on the clear side of the two filter sheets, which means that the direction of flow is from the outside to the inside. The outer edge of the filter is given an injection-molded polypropylene frame, creating a closed filtration system.
The individual filter cells are stacked on top of each other with plastic intermediate rings until a certain height is reached. The filtrate runs off through this inner core. Adapters (O-ring or flat gasket) are then attached to the inner core of the filtration system to stabilize the filter cells and connect them to the filtrate line. The entire assembly forms a 12″ or 16″ diameter filter module with 16 filter cells.

Sheet types for SF-DISC
The actual filtration takes place through the filter layers, which are available with different filtration properties. The different layer types of the SF-DISC modules for deep-bed filters cover all areas from coarse particle filtration, clarifying filtration, and sterile filtration to the separation of microorganisms.
