Microfiltration is a filtration process that uses filters with pore sizes from 0.1 to 10 micrometers to remove particles and bacteria from water or other liquids. It is commonly used in water treatment applications, pharmaceutical and food industries, among others. It is considered an intermediate form of filtration, between coarse filtration and ultrafiltration.
Its working process is quite simple. The liquid to be filtered is pumped through the filter, where particles and bacteria present in the liquid are trapped on the surface or within the pores of the filter. The filtered water or liquid is then released from the other side of the filter.
There are different types of microfiltration filters, such as membrane filters, which are composed of a thin layer of porous material such as polyester, cellulose or polypropylene, and ceramic filters, which are composed of tiny pores in a ceramic structure.
The filter should be cleaned periodically to remove accumulated particles to ensure process efficiency and extend filter life. This is usually done through washing processes such as compressed air washing, chemical washing or mechanical washing, depending on the type of filter and the liquid to be filtered.
Microfiltration is capable of removing particles and bacteria between 0.1 and 10 micrometers in size, which is useful for purifying water or other liquids.
Microfiltration can handle high flow rates, which makes it suitable for industrial and community applications.
Microfiltration is a simple and easy process to operate, and microfiltration filters are generally easy to clean and maintain.
Low operating costs:
Microfiltration can be used to remove pathogenic microorganisms from water and other liquids, which increases the microbiological safety of the treated liquid.
Microfiltration does not remove the minerals and nutrients present in the water, unlike other filtration processes.
