AFM
Activated Filter Media

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.

cdc.gov

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

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

Tube well and ground water

Ground water is the preferred source of water in many countries in order to avoid human pathogens.  However this is not always the situation,  depending upon the depth of the the tube well and the age of the water,  there may well be biological contamination. The ground water may be a few hours  to many thousands of years old,  the older the water, the less likely there will be  viable pathogens in the supply.

Over the last 40 years there has been a huge increase in the number of tube wells in an effort to obtain water that is non pathogenic. Contaminated water can cause diarrhoea disease and dehydration leading to mortality amount infants and the elderly.  This was the main drive to sink tube wells and 10's of millions have been drilled in India and around Asia and Africa.  Many aid agencies also just drill tube wells and fit a pump, without analysing the water, of checking the quality on a regular basis.  As a consequence,  in countries such as;

  • Bangladesh
  • India, West Bengal
  • Vietnam, Red River

and many other locations,  the water has very high arsenic concentrations,  the following are some other issues.

  • arsenic
  • fluoride
  • chromium
  • ferric & manganese
  • selenium
  • uranium

We are now in a situation in Bangladesh and India where we have the greatest human poisoning in history, attributed to arsenic and most of it was funded by the world bank and aid agencies.  The upper limit for arsenic is 10ppb,  filtration systems such as CAFE should be used to treat all water, including tube well ground water.
