Filter Control is one of the most important applications in the brewery in order to maximize efficiency, prevent filter clogging and ensuring final beer clarity. Modern breweries control this crucial process step, either having standard Kieselguhr filters, membrane filtration units or stabilization filters.

Dual beam scattered light sensors are used to control filter performance, particulate breakthroughs and beer haze. Additional sensors connected to the system can help monitoring feed, filter backwash cycles and phase separation.

Final Beer Filtration Benefits |
- Ensure final beer haze
- Optimize filter performance
- Optimize filter backwash cycles
- Reduce product loss
- Ensure final product quality
|
| Filter Control 11°/ 90° |
The optek Haze Control / DTF16 relies on a dual angle scattered-light measurement for precise quality control during final filtration. Using this sensor downstream of the filter detects filter breakthroughs, preventing “out of spec” product while ensuring product quality and clarity at each filtration step.
|
| Feed Monitoring |
Using an optek AS16-N or AF16-N, the turbidity in the feed line can be monitored, allowing precise feed control while preventing filter clogging or blinding. This additional sensor can be connected to your Haze Control / DTF16 system.
|
| Filter Backwash Optimization |
Dosage of filter aids like Kieselguhr or PVPP can be controlled with optek absorption or scattered-light sensors. Optimizing filter aid usage to reduce cost and at the same time ensuring consistent product quality.
|
| Phase Separation |
The Haze Control / DTF16 system may also be paired with an AS16-F or AF16-F to measure the color of your beer. This measurement controls the phase separation between beer and water ensuring faster product changeovers while maintaining product quality and minimizing product losses.
|
| Filter Setup Monitor |
Using the 0° absorption channel of the sensor DTF16, turbidity up to 500 EBC can be measured, allowing you to monitor and control the filter pre-coat cycle. This provides an additional opportunity for filter optimization.
