Integrity Testing
Trapfil™ filter cartridges are batch tested for integrity using the Bubble Point Test. Procedural details are available from Porvair.
Effective Filtration Area
Up to 0.6m2 per 250mm module.
Applications
Trapfil™ cartridges are suitable for the guard filtration of a wide range of beverages, to enable the economic removal of diatomite and PVPP particles.
- Stabilisation
For the removal of coarse and fine PVPP powder used in the beer and wine stabilisation processes. - Clarification
For the removal of kieselguhr powder used in the beer and wine clarification processes.
Clean Water Flow Rates
- Typical clean water flow rate:
A 254mm (10”) Trapfil™ single cartridge exhibits the flow-ΔP characteristics indicated below, for solutions with a viscosity of 1 centipoise. - Other solutions:
For solutions with a viscosity of greater than 1 centipoise, multiply the indicated differential pressure by the viscosity in centipoise.
