A membrane filter comprises a membrane provided with pores with a pore size between 5 nm and 50 νm.
The invention further relates to a method for detecting membrane leakage in such membrane filter device.
The pre-filter (8) has a higher capacity than the membrane filter (9).
The present disclosure relates to a process and a device for testing a hollow fibre membrane filter comprising two compartments separated by a porous membrane.
Examine the membrane filter using a (stereo-)microscope or a trichinoscope.
There is described a membrane unit wherein at least two outer casing portions are sealed together around a membrane.
Positioned in the circuit is a container (2), the container (2) being pressurised.
Once the puzzle is assembled, it is adhered to the mounting sheet, so that it can be kept in an assembled state.
remove the filter holder and transfer the membrane filter to a slide or Petri dish
The water is flushed out from the inside of the membrane filter (300) through the flush regulating valve (310) while removing scales from the inside of the membrane filter (300) under flushing pressure thereof.
Means for performing reverse filtration in the membrane filter (52) are also included for maintaining a consistent level of filtration through the membrane filter (52).
