Graded density filter for high flow production of Cryptosporidium - free water is available from Porvair Filtration Group. Cryptofil™ filter cartridges are proven to provide absolute control of Cryptosporidium oocysts in water used in the food, beverage and ultrapure water industries. The Cryptofil™ cartridge was developed by Porvair after extensive research and has resulted in filter media with continuously graded fibre density which enables progressively finer oocyst retention through the depth of the media. This graded density depth filtration mechanism, combined with optimized pleated pack configuration and resultant high surface area, affords high flow capability and exceptional oocyst retention capacity. Cryptosporidium oocysts removed from the water flow are captured within the media and are not subject to release by system fluctuations. The voids volume of Cryptofil™ combined with advanced cartridge construction that can be steam, hot water or chemically sterilised results in a filter capable of retaining high concentrations of oocysts ensuring extended service life and reduced filtration costs.
