A comprehensive overview
Cryptosporidium is the causative agent of cryptosporidiosis. It is a microscopic parasite, transmissible from person to person, through contact with infected animals, or by ingestion of contaminated water or food.
Cryptosporidium forms cells called oocysts, with a diameter ranging from 4 to 6 µm.
This parasite is responsible for the transmission of cryptosporidiosis, a diarrheal disease. Oocysts are resistant to heat and cold, can remain viable for more than three months, and can survive for over one year in seawater. They are also resistant to chlorine-based disinfectants.
Water is the primary vehicle of foodborne contamination, particularly distribution network water. Monitoring water quality therefore represents a major concern for food and beverage producers, municipal water suppliers, and all companies whose products may have an impact on consumer health.
Different methods are required to disinfect water supplies: UV, ozone, or electrolyzed water.
Ultraviolet treatment requires a relatively short contact time and avoids the use of chemical products. However, the effectiveness of this process is limited if the water contains organic matter or if the UV dose is insufficient (end-of-life lamps / poor transmission).
Ozone generates bromate, and its effectiveness is reduced in cold water.
Finally, electrolyzed water may alter the properties of the solution.
Compared with the methods described above, absolute filtration is an effective solution to prevent and eliminate the risk of introducing contaminated water into food processing applications in particular, and industrial applications in general.
In summary
Presence of Cryptosporidium:
- Causes a diarrheal disease
- Transmitted from person to person
- Resistant to heat and cold
- Resistant to conventional chlorine-based disinfection, including bleach
- Remains viable for more than three months
- Can survive for more than one year in seawater
Pemflow solutions
Afin d’éradiquer les oocystes de Cryptosporidium dans l’eau des aliments, des boissons et les industries produisant de l’eau ultrapure, on a recours à des cartouches Pleated filter cartridges made of polypropylene or nylon 6, offering reliable and consistent performance.
The filtration system is equipped with filter cartridges featuring a large filtration surface and a graded-density depth filtration mechanism. This mechanism provides exceptional oocyst retention capacity and remains effective at variable flow rates.
The filters achieve an absolute retention rate greater than 99.998%, i.e. a beta ratio of 5000.
The specifications of CRY-grade cartridges (Cryptosporidium) are as follows:
- Cage, core & end caps: 100% polypropylene
- Absolute retention
- Materials compliant with US FDA Title 21 and USP Class VI requirements
- Suitable for food contact in accordance with EC 1935/2004
- Cryptosporidium grade – Log reduction of 10⁴
- Individual, antistatic packaging
The use of CRY-grade filters provides excellent turbidity reduction, a modular, flexible, and cost-effective solution, with no start-up rinsing required.
Eliminating Cryptosporidium present in water is critical for many industries, such as mineral water and beverage production, and the use of process and wash water in the food industry.
