Cryptosporidium Drinking Water Tap Safe To Drink Filter

Cryptosporidium, we filter that.

Cryptosporidium is found in every part of the United States and throughout the world. Millions of Cryptosporidium can be released in a bowel movement from an infected human or animal. Cryptosporidium may be found in water sources such as private wells that have been contaminated with feces from infected humans or animals. Water can be contaminated through sewage overflows, sewage systems that are not working properly, polluted storm water runoff, and agricultural runoff. Wells may be more vulnerable to such contamination after flooding, particularly if the wells are shallow, have been dug or bored, or have been submerged by floodwater for long periods of time.

What is Cryptosporidiosis?

Cryptosporidiosis ((krip-toh-spore-id-ee-OH-sis), is a diarrheal disease caused by a microscopic parasite, Cryptosporidium, that can live in the intestine of humans and animals and is passed in the stool of an infected person or animal. Both the disease and the parasite are commonly known as “Crypto.” The parasite is protected by an outer shell that allows it to survive outside the body for long periods of time and makes it very resistant to chlorine-based disinfectants. During the past 2 decades, Cryptosporidium has become recognized as one of the most common causes of waterborne disease (recreational water and drinking water) in humans in the United States. The parasite is found in every region of the United States and throughout the world.

Water Treatment

Water treatment for Cryptosporidium relies on properly designed and operated filtration systems. Chlorine disinfection of the organism is ineffective, as it has been shown that even one oocyst can withstand pure bleach (50,000 ppm chlorine) for 24 hours and still cause an infection.  Filter systems usually consist of several filters. A "roughing filter" containing a 5µ - 10µ (micron) cartridge filter is installed to remove any large diameter sediments, such as iron sediments, sand, salt , etc. Downstream from the roughing filter, a "polishing filter" containing a <1µ absolute cartridge filter is installed to remove small particles including Cryptosporidium, from the water. Most reputable water system vendors are currently recommending a filter porosity of <1µ to submicron or membrane filters to remove Cryptosporidium cysts and trophozoites from drinking water.  

We have designed and tested several of our products to remove Cryptosporidium from drinking water.
