APPLICATION IN CONTEXT
- Fermentation and maturation
- Clarification
- Trap and prefiltration
- Final membrane and bright tank
- Carbonation and filling
Connections to review
- 01 → 02 Fermented beer
- 02 → 03 Clarified beer
- 03 → 04 Prefiltered beer
- 04 → 05 Final filtrate
- 05 → 05 Filtered CO₂ → carbonation and filling
The selected steps depend on beer style and heat treatment. The final membrane lane illustrates one microbial-stabilization strategy.
The pictured ROKI TECHNO adsorption cartridges are reviewed for clarification/pretreatment. Their role is separate from downstream final membrane filtration; verify microbial-retention performance, filter grade and integrity-test conditions using evidence for that membrane.

Connection principles and operating/test methods
From clarification to final filtration
Fluid
Scroll horizontally to see the complete flow.
Choose the clarification method and need for final filtration according to beer style. Validate retention of the target microorganisms. Lines show process order, not microbial removal rates or filter life.
These conceptual views explain flow direction. Actual piping, wiring and physical flow rates require a separate design.
01 — PROCESS
Where does each step fit?
Define the intended use and conditions to identify the required role of each item.
Trap filtration and pretreatment
Capture escaped filter aid and remaining particles to protect the final membrane.
Final filtration and filling
Review validation data for the target microorganisms alongside filler hygiene and the gas supply.
02 — SELECTION
What should be selected and verified?
Clear lagers and beers that retain haze do not share the same filtration objectives. Separate the roles of yeast and filter aid retention, final filter protection, and spoilage microorganism control, and relate them to bottling and canning conditions.
Scroll horizontally to review all columns.
| Process objective | Step to review | Selection evidence |
|---|---|---|
| Visible turbidity | Clarification / trap filter | Yeast, diatomaceous earth carryover, target turbidity, and product style |
| Final membrane life | Multistage pretreatment | Particle size and colloidal load, throughput per unit area, and differential pressure rise |
| Microbial stability | Validated final membrane | Target spoilage organisms, retention performance, and integrity before and after use |
| Preserving carbonation and aroma | CO₂ and vent filtration; operating conditions | Gas quality, bubbles, dissolved oxygen, and residual cleaning solution |
These examples start the application review. Pore size or nominal rating alone does not establish suitability or retention; confirm with the actual process fluid and supplier evidence.
03 — OPERATING CHECKS
Use operating data to identify improvements.
Do not base replacement on differential pressure alone
Compare differential pressure at the same flow and temperature, and also apply the manufacturer's pressure limits, hygiene procedures, and validated number of uses.
Low-turbidity beer can still foul filters rapidly
Colloids and deformable particles affect fouling. Compare pretreatment combinations using small-scale filterability tests.
Record quality indicators together
Check turbidity, dissolved oxygen, microorganisms, sensory properties, and product loss per batch before and after filtration.
04 — QUESTIONS
Frequently asked questions
Is the same pore size used for every beer?
No. It depends on beer type, target microorganisms, and whether subsequent heat treatment is used. Do not judge final filtration performance from the stated pore size alone.
Will a finer membrane last longer?
A finer membrane may actually foul faster. First compare pretreatment retention mechanisms and area, as well as recovery after cleaning.
05 — APPLICATION REVIEW
Prepare the conditions for a technical discussion.
These details help narrow the configuration and the evidence to review.
- Beer style and whether heat treatment is used
- Batch volume, flow, and temperature
- Pretreatment and final filter configuration
- Differential pressure trends and replacement interval
- Target microorganisms, turbidity, and dissolved oxygen

Agree the comparison criteria before testing.
Define current conditions and improvement goals before introducing a new filter. Sample and testing availability, who performs the work, costs and timing require separate agreement.
- Document current conditions — Flow, temperature, differential-pressure trend, throughput and replacement interval
- Agree comparison criteria — Throughput, product loss, quality indicators and test conditions
- Confirm the work scope — Responsibilities and costs for samples, test location, measurements and results review
- Review results and remaining checks — Comparison results, remaining uncertainties and evaluations needed before site use
