LIFEA™ is the first cellulose triacetate membrane developed by Degremont Technologies - Aquasource. Triacetate material is naturally hydrophilic and therefore offers limited clogging. This membrane is available in a wide range sizes: from 1 to 125 m² of filtration area per module.
MEMBRANE TECHNOLOGY: LIFEA™
LIFEA™ is a Degrémont Technologies – Aquasource ultrafiltration
membrane with one of the lowest cut off value of the market
Ultrafiltration is simply a physical process where clarification and filtration stages are both carried out simultaneously. Ultrafiltration is a low pressure process.
Ultrafiltration is a barrier to all particles larger than 0.01 micron: pollen, algae, parasites, bacteria, viruses, germ and large organic molecules. The result is a perfectly pure water, with a balance of mineral salts maintained a turbidity lower than 0.1 NFU.
HOW IT WORKS
LIFEA™ is a hollow fibre membrane filtering from the inside to the
outside. The fibres are assembled in bundles and then placed
inside a composite tube.
The bundles are held together using resin, providing perfect and permanent sealing of the module, thus achieving very high efficiency rates with respect to virus retention.
The retained particles accumulate on the surface of the skin and are therefore easily removed when cleaning in reverse flow.
