Integrity Testing
Each Cryptofil™ module of every cartridge is individually integrity tested using the Bubble Point Test. Procedural details are available from Porvair.
Effective Filtration Area
Up to 0.6m2 per 250mm module.
Applications
Cryptofil™ cartridges provide absolute filtration where reproducibility and consistency of performance are critical. Cryptofil™ cartridges are recommended for the production of oocyst-free water in the following applications:
- Mineral Water
- Food Processing
- Leisure
- Embarkation Water Supply
Process water used in the manufacture of food stuffs and decontamination of process equipment. Recommended for use in fresh food preparation, such as fruit and salad washing.
Clean Water Flow Rates
- Typical clean water flow rate:
A 254mm (10”) Cryptofil™ 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.
