The brewer of today has many challenges. Beer quality must be outstanding, all resources need to be maximally utilized and the output of beer must be as high as possible. Besides, the consumer is requesting to have an extended choice of beers, produced in an environmental and safe way.

For over decades Pentair is market technology leader in Beer Membrane Filtration and many breweries all over the globe implemented the BMF systems in their operation to have the perfect beer against the lowest possible cost level.

We’ve gone one step further and developed our Smart Beer Membrane Filter, the BMF +Flux Smart S8 suitable for beer filter lines with a capacity from 7,000 hl/d up to 22,000 hl/d.



  • Low energy consumption because of no centrifuge
  • Solid waste stream is reduced by up to 50 %
  • Safe and hygienic work environment

  • Consistent beer quality
  • Better taste stability due to no iron pick-up
  • Permanent barrier to beer spoiling bacteria

  • Predictable output
  • Non-stop beer flow
  • Simple process provides easy operation
  • Easy to fully automate
  • Less labor—No DE-handling

  • Beer loss down to 0.1 %, with no pre- and after- run tank
  • Fixed cost for membranes per hectoliter - predictable and simple
  • Low OPEX due to small system volume and integrated inline cleaning
  • No downtime


The BMF +Flux Smart S8 consists out of a master controller and multiple membrane units. The core of the design is that the membrane units are able to filter and clean independently of each other, making it a self-foreseeing beer filter. Even when the quality of resources has fluctuations, the smart steering controller makes sure the system runs as efficient as possible. Furthermore the smart steering controller decides which unit has to run, at which flow rate, and which unit can do a cleaning. This implies a reduction of downtime to zero and a non-stop beer flow!

A BMF makes use of proprietary membrane technology owned by Pentair. Pentair’s membrane fiber technology has several advantages compared to the use of diatomaceous earth filters: beer ageing is strongly reduced and beer quality is consistent. Besides the use of membranes is sustainable and environmental friendly.


A BMF makes use of proprietary membrane technology. A membrane is a thin polymer layer with pores working like a sieve in the shape of a fiber. Turbidities like yeast and proteins are retained while beer flows through the pores. The membrane is used for many filter run-cycles, which is possible because of an optimized cleaning protocol. The membrane is made from polyethersulfone (PES) which is known for its great compatibility with food and beverages and can withstand cleaning agents and high temperatures. Thousands of membrane fibers form a module, and 4-18 modules are packed into a membrane unit.

Typically, Pentair’s BMF system consists of an unfiltered beer tank, the membrane filter system, and a filtered beer tank, along with a designated cleaning agent cabinet. In existing breweries, reuse of the current tanks in the filter line is possible, which helps minimize capital expenditures.

BMF systems offer unique features with the PES membranes, the optimized filtration process, and the inline cleaning method. The optimized filtration process withstands large amounts of yeast, and yeast even has a positive effect on the run volumes. Because of this, pre-clarification of beer with a centrifuge is not necessary. These features help breweries save on capital expenditures and energy use, plus help avoid expensive maintenance costs. As a result, the brewery benefits in the areas of sustainability, quality, operation, and expenditures.

Pentair’s BMF provides flexible installation and integration. The preassembled filter units are stand-alone solutions on a stainless steel frame. The compact modular design of the skids fits even challenging space requirements and since no DE handling/ kitchen/ storage is required, valuable space can be saved. 

To install the BMF in an existing brewery all that is needed are incoming and outgoing beer connections, water, power, compressed air, and carbon dioxide.
