The BMF Compact offers a turnkey filtration solution for breweries with an annual output of up to 1,500,000 hectoliters and a capacity 1,500–6,000 hl/d.


The Pentair Beer Membrane Filtration System (BMF) enables a sustainable brewing process and a working environment free of health and safety risks that were present in the Diatomaceous Earth (DE) era of filtration. Pentair delivers beer membrane filtration systems, their components and related services from small to large scale solutions. With our BMF system, you save on waste disposal and product loss, and also benefit from measurable improvements in beer taste and stability - resulting in pure consistency.

The BMF Compact System offers a turnkey filtration solution for breweries with an annual output of up to 1,500,000 hectoliters and a capacity of 1,500–6,000 hl/d.

The BMF Compact is premounted as a stand-alone, containerized unit and can be quickly put into operation with the first filtered beer available in just two weeks after start-up. Operating in batch processing, the BMF Compact requires limited manual labor as the main process steps are fully automated.

The Pentair BMF filters more beer in a smaller footprint than any other available technology. BMF is also designed to be a future-proof system. It enables breweries to invest in only what they need now and expand at the pace brewing demands. Modularly designed skids can be added to the filter line as needed, which limits upfront investments for extra capacity.

Next to optimum flexibility, the scalability of the BMF Compact skids also offers breweries an easy option to neutralize the quality fluctuations of raw materials. With BMF Compact, brewers can be confident in both the quantity and quality of their beer output. In addition, the process flexibility is increased due to the system’s unique start-stop-procedure.

Functional Description

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.

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.
