Polymeric Membranes

Polymeric Membranes is a technology of liquid separation that is industry leading in both performance and efficiency. These membranes are generally identified in four major categories, based on performance characteristics and specific separation attributes. The polymers used in the production of different membranes are specifically selected in order to get optimal performance in a selected fluid and process environment. Compatibility with the fluid(s), as well as with cleaning agents necessary to aid in hygienic and performance stability must be taken into consideration when selecting a specific membrane technology.

Membrane technology explained below uses materials with pour size in micrometers (µm), or MICRON.

MICROFILTRAION

Microfiltration (MF) technology explained. It refers to a category of membranes where separation range (pore size) is typically considered to be about 0.1 µm (micrometers or micron) and greater.

ULTRAFILTRATION

Ultrafiltration (UF) technology explained. It refers to a category of membranes separation range (pore size or molecular weight cut-off (MWCO)) is expressed in Daltons (Da) or kilo-Daltons (kD), and is in a range of 1,000 Da (1kD) to 100,000 Da (100kD). For drinking water, it is around 0.2 micron to filter out bacteria.

NANOFILTRATION

Nanofiltration (NF) technology explained.
