Diatomaceous Earth Filter for Beer Clarification

A diatomaceous earth filter uses a layer of diatomite (DE) powder as the filtration medium to remove yeast cells, protein haze, and fine suspended particles from beer. Because DE filtration achieves a much finer level of clarification than bag or coarse membrane filters, it is commonly installed as the final polishing stage immediately upstream of a keg filling machine — ensuring the packaged beer meets the desired visual clarity and stability standards. ZR BREW’s DE filter is built in SUS304 or SUS316 stainless steel for sanitary food-grade applications.

The three filtration systems serve different stages and precision levels in the brewery filtration workflow. A bag filter performs coarse pre-filtration, removing larger particles and sediment from the liquid stream. A three-stage membrane filter provides multi-stage precision filtration using membrane housings in series. A diatomaceous earth filter uses a diatomite cake to achieve deep clarification — removing fine yeast residue and protein haze that other filter types may pass. In many brewery filling lines, these three systems are used in sequence for progressive filtration from coarse to polished output.

Yes. ZR BREW supports full customization of the DE filter configuration, including filter area sizing, DE dosing setup, material grade (SUS304 or SUS316), inlet/outlet diameter, connection type (tri-clamp, threaded, or flanged), and pump specification. The system can be tailored for different beer styles (lager, ale, wheat beer, etc.), clarity targets, and production volumes. Please share your beer type, required filtration level, target flow rate, and filling line specifications when submitting an inquiry.

No external pump is required. The diatomaceous earth filter includes an integrated pump for active liquid drive and a built-in control panel for process management, allowing the unit to operate as a standalone filtration station. The pump supports 220V, 240V, 380V, and 415V power configurations, making it suitable for brewery facilities across Europe, North America, South America, Southeast Asia, and other international markets. Custom voltage configurations are available on request. Buyers should confirm their local power supply voltage and phase count before ordering.

Before placing an order, buyers should confirm: (1) beer type and target clarity level (visual or analytical standard); (2) required filtration flow rate and operating pressure; (3) inlet/outlet pipe diameter and preferred connection standard (tri-clamp, threaded, or flanged); (4) material grade preference (SUS304 or SUS316); (5) downstream equipment type — specifically the single-head keg filling machine model and filling line piping layout; (6) local power supply voltage and phase for the integrated pump; (7) whether upstream coarse filtration (bag filter stage) is already in place; and (8) available floor space and whether fixed or mobile installation is preferred.
