Craft Brewery: What Type Of Filter Should I Use For Best Results?
What is Filtration?
Filtration generally refers to beer clarification through several stages to produce a crystal-clear end product, and when it comes to finding that ideal taste and colour for your beer, it is important to note the type of filter being used in the filtration process. Now how do you get the best results for your beer? Well, the purpose is to remove suspended non biological materials and residual yeast, which would otherwise cause the beer to be hazy.
Let’s Talk Filters
Filters are used not only to clarify beer but to clarify wort, recover wort from separated trub, and recover beer from tank bottoms. The best practice being used today in craft breweries is membrane filtration. A membrane is a thin layer of semi-permeable material that separates substances when a driving force is applied across the membrane. Membrane processes are increasingly used for removal of bacteria, microorganisms, particulates, and natural organic material, which can impart colour, tastes, and odours to water and react with disinfectants to form disinfection byproducts. Industry applicable filters such as, 4040 ro membrane filters and the PES pleated cartridge filters are heavily used in breweries, wineries, and water treatment facilities to ensure beverage-purpose water meet safety regulations.
Advantages of Membrane Filtration
In industrial applications where reliability, consistency, and operating costs are critical for success. Membrane filtration offers a significant advantage in these desired areas.
Reduces operating costs for ro systems
The process can function effectively at low temperatures
Energy requirements are low
Membranes can be manufactured in a highly precise manner
No phase changes involved, both feed and product streams remain in liquid form
