LANGENLONSHEIM, GERMANY … The Filtration Division of power management company Eaton provides innovative filtration solutions for the global food and beverage industry. Eaton recently expanded its range of BECO® pre- and membrane filter cartridges. BECO PROTECT PG™ and BECO PROTECT FS FineStream™pre-filter cartridges and the new BECO MEMBRAN PS Beer™ membrane filter cartridge offer the perfect combination of pre-filtration and final filtration for stable and bright beer.
For beer filtration, a two-stage pre-filtration system effectively protects downstream membranes. In the first stage, a pre-filter from the BECO PROTECT PG range with a retention rating (ß ratio ≥ 5000) of 5 or 10 µm is used as a particle filter. In the second stage, a fine filter from the BECO PROTECT FS FineStream range with a retention rating of 0.3 or 0.5 µm helps ensure optimal preparation of the beer for the next step, membrane filtration, by reducing the colloids, proteins and tannins that can result in premature membrane blockage. For sterile filtration before bottling, the BECO MEMBRAN PS Beer membrane filter cartridge, which can be tested for integrity and has an absolute retention rating of 0.45 or 0.65 µm, can be used as a downstream “police filter” to reduce or remove yeast and bacteria.
The polypropylene fleece of the BECO PROTECT PG pre-filter cartridge are produced individually and are wrapped around the inner core from the outside in at a ratio of 10:1, creating a stable, increasingly tight funnel with a high particle retention capacity. Wrapping in layers from coarse to fine also improves mechanical stability and enables effective backwashing at up to 2 bar and 80 degrees Celsius.
The innovative and unique special pleating of the fine polypropylene fleece in the
BECO PROTECT FS FineStream pre-filter cartridge provides outstanding results; increasing the filter area in the filter cartridge while keeping the pressure difference at a low level. The service life of the pre-filter cartridge is significantly longer than wrapped standard filter cartridges. The looped pleating around the inner core ensures the individual loops hold each other in place and maximize mechanical stability. This special design also helps prevent deformation of the pleating during backwashing at up to 2 bar and 80 degrees Celsius.
The BECO MEMBRAN PS Beer membrane filter cartridge, which is specifically designed for beer filtration, is optimally tailored to the requirements and long service life of final filtration. The filter material consists of pleated polyethersulfone and, with an LRV (Log Reduction Value) greater than 7 per cm², provides high microbiological retention. The membrane’s asymmetrical pore size distribution minimizes blockages and increases service life. With 0.78 m² per 10-inch element, the filter area is designed for high flow rates and a long service life. The fully welded design with additional polypropylene support fleece increases mechanical stability, withstands a differential pressure of 5 bar in and 2 bar against the direction of flow at 20 degrees Celsius, as well as more than 100 steam cycles. Another advantage is the wide chemical compatibility (pH 1 to 14), enabling various detergents to be used in the regeneration cycle.
