Characteristics
FIBRAFIX® depth filter sheets represent an approved and established filtration technology for solid liquid separation. The three dimensional medium assures superior retention capacity for solid particles at a high flow rate.
The pore sizes can be fine enough to retain bacteria and thus produce a sterile liquid (logarithmic retention of bacteria up to LRV 8). The dirt holding capacity of a FibraFix® depth filter sheet can be up to 4 kg per m². In the filtration process, solid particles are slowed down and eventually retained by the tortuous path inside the filter sheet and by electrokinetical interactions («zeta potential»). Through this unique mechanism, a high capacity (long lifetime of filter until plugging) can be achieved.
All materials are food grade and FDA approved.
Applications
The broad variety of available porosities allow for their use in a wide range of applications. Porosity grades are available from coarse over fine to germ reducing and germ removing filtration («sterile filtration»). Examples of industries:
