Microfiltration is a technique used to physically separate elements. It uses filtering membranes with pore diameters between 0.1 and 10 micrometers.
Microfiltration therefore eliminates suspended matter, micro-algae and bacteria present in a liquid.
In addition, some viral proteins are also eliminated, not because they are caught by the pores, but by fixation on the bacterial biofilm that grows on the membrane.
Applications of microfiltration
Microfiltration is used for water pretreatment and water treatment , elimination of bacteria and solid particles from food liquids (milk, oil) and decontamination of effluents.
