There are over 2 billion cases of water relate disease every year.
More people die from lead posioning than from malaria

There is no excuse, AFM inside a CAFE filter is a simple sustainable solutions for most of the issues.

Hepatitus A

Virus infection, causes vomiting, diarrhea, abdominal pain, dehydration and liver damage. 100 million cases per year.

Virus

Vibrio cholerae

Cholera, serious bacterium infection, often fatal if untreated. Bacterium hides inside copepod water insects which give then protection from chlorine.

bacterium

E.coli

Some bacterium strains are pathogenic. E.coli is used as a faecal bacterium indicator. If it is found then there are likely much more serous issues with the water.

bacterium

Campylobacter

Bacterium causing diarrhoea, and can cause dehydration in children. Very common and can cause serious infection.

medicalexpress

bacterium

Shigella dysenteriae

In excess of 200 million cases a year, high mortality risk from diarrhoea, dysentery, and dehydration.

bacterium

Salmonella typhi

Typhoid, 30 days after exposure may cause headache, abdominal pain. Mortality 25% without treatment. 20 million known cases per year.

cdc.gov

bacterium

Naegleria fowleri

Brain disease, no treatment available, infection is fatal. 7 to 15 um cyst stage. Common in South East Asia

© 1984, American Society for Microbiology

Parasite

Amebiasis

Can cause dysentery, liver damage and bowel disease. Cyst size 10 to 20 um

cdc.gov

parasite

Giardia

Parasite, cyst is 20 um in size. Causes aggressive diarrhea, vomiting, dehydration. Over 0.5 billion cases a year

cdc.gov

parasite

Cryptosporidium

The most common water borne disease, causes serveral billion infections every year. Diarrhea, dehydration, vomiting. Not killed by chlorine, but removed by Cafe with AFM

cdc.gov

parasite

Arsenic from drinking ground water, over 1/2 billion people around the world suffer from arsenic. Learning difficulties, kidney and lung damage, cancer.

Surface water characteristics and quality

Surface water may be derived from the following sources;

  • IMG 0284.JPG (2)pond water, with control over the catchment area to minimise pollution
  • lake or reservoir
  • river water

In many cases ground water or tube well water ends up being the same as surface water becuase of infiltration of surface water into the aquifer, either by entering an unsecured tube well,  or through fissures in the ground. Ideally water quality should be checked on a regular basis for contamination. However this is not always possible, and this is one of the reasons for the design of the CAFE filter with AFM.

Surface water will always have biological contamination and pathogens, either from human or animal origin.   The key ones are;

  • cryptosporidium,  oocysts measure 4 microns
  • giardia, oocysts measure 20 microns
  • nematodes such as Ascaris, measures 40 microns

The above is only a small sample of parasites found in water supplies,  there will also be bacteria, viri, and fungi
