LifePure, PES membrane cartridge by Exova

Description

The LifePure is an asymmetric polyethersulfone (PES) membrane filter cartridge for controlling microorganisms and removing particles in industrial processes. The catalog specifies it for the final filtration of bottled water, wine, and unpasteurized alcoholic beverages, and as a prefilter ahead of final filters.

The membrane has open pores on the outer face that narrow down to the final pore of the filter: it allows high flow rates with low pressure drop and has a high contaminant retention capacity. There are six ratings, from 0.1 to 1.2 µm, with 6,000 cm² of filtration area per 10″. The 0.1 µm rating also retains Acholeplasma laidlawii.

It withstands repeated sanitization cycles with hot water at 80 °C and with chemical cleaning and disinfection agents, as well as multiple steam sterilizations in-line or in an autoclave. This resistance allows the cartridge to be reused.

Six ratings, from 0.1 to 1.2 µm

0.1 · 0.2 · 0.45 · 0.65 · 0.8 and 1.2 µm, in lengths from 10″ to 40″ and with 6,000 cm² of filtration area per 10″.

Sterilizing retention at 0.1 and 0.2 µm

More than 10⁷ Brevundimonas diminuta per cm², according to the FDA definition of sterilizing-grade filters.

Acholeplasma laidlawii retention

The 0.1 µm rating retains more than 10⁴ Acholeplasma laidlawii per cm².

Steam, hot water, and chemicals

Cycles of 30 to 60 minutes with steam at 121 °C, water at 80 °C, peracetic acid, or sodium hydroxide at 1 %.

Frequently asked questions

Which rating retains Acholeplasma laidlawii?

The 0.1 µm rating, with more than 10⁴ Acholeplasma laidlawii per cm². The 0.1 and 0.2 µm ratings also retain more than 10⁷ Brevundimonas diminuta per cm², according to the FDA definition of sterilizing-grade filters.

What applications is it used for?

The catalog specifies it for the final filtration of bottled water, wine, and unpasteurized alcoholic beverages, and as a prefilter ahead of final filters.

Can it be steam-sterilized and reused?

Yes. It withstands multiple cycles of 30 to 60 minutes with steam at 121 °C, in-line or in an autoclave, and of sanitization with water at 80 °C. The catalog recommends them for single-open-end cartridges (configurations B to E).

What differential pressure does it withstand?

Up to 5.5 bar (80 psi) at 25 °C in the forward direction and 0.69 bar (10 psi) at 25 °C in reverse flow. The maximum differential pressure for cartridge change-out is 2 bar.
