LifePure W, PES membrane cartridge for beer and wine by Exova

Description

The LifePure W is a polyethersulfone (PES) membrane filter cartridge in a single-layer configuration. It was developed for the food and beverage industry, especially for the filtration of beer and sparkling wines.

It is offered in a single rating, 0.65 µm, which retains more than 10⁷ Saccharomyces cerevisiae per cm². It is used as a final filter before bottling or as an integrity-testable prefilter, and has 8,000 cm² of filtration area per 10″.

The membrane is chemically resistant and stable across the pH range of 1 to 14. The cartridge withstands repeated sanitization cycles with hot water at 80 °C and with chemical cleaning and disinfection agents, as well as multiple steam sterilizations, so it can be reused.

0.65 µm rating

Retains more than 10⁷ Saccharomyces cerevisiae per cm²: particles and yeasts stay in the filter before bottling.

Single-layer PES membrane

Designed for beer, wine, and sparkling wine, with 8,000 cm² of filtration area per 10″.

Stable from pH 1 to 14

The PES membrane is chemically resistant across the entire pH range of 1 to 14.

Integrity-testable prefilter

Serves as a final filter before bottling or as a prefilter with integrity testing. Integrity is tested at the plant.

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 %.
