J. Huesa - Microfiltration System
Filtration within a porosity zone between 0.1 µm – 10 µm, which allows the removal of suspended solids, fine particles, colloids, algae, and microorganisms, among other elements. The force that facilitates the passage of substances through the membrane comes from a pressure gradient.
In this case, the filter medium is a membrane whose characteristics vary in function according to its configuration. Most commonly, the membranes are configured as fibers (referred to as hollow fiber membranes). The materials used in the manufacture of membranes are very diverse, with polyamides, cellulose acetate, PVDF, and polysulfones being the most common.
The most widespread application of this technology is in sectors in which the water cannot contain micro-particles, which are of a size that is difficult to retain through conventional systems.
Some of the most widespread uses are:
- Reverse osmosis and nanofiltration pretreatment (using 5 to 10 micron cartridges)
- As a final refinement in a filtration process
- For potable and wastewater reuse
- Process water for the food and pharmaceutical industries
Some of the advantages of its application are:
- Low energy requirement
- Reduction in facility size
- Reduction of the use of chemicals
