Ceramic Water Filters
Modern technology has improved ceramic water filters over the past decade many times over. One pioneering method in use today in ceramic water filters is the use of silver which is impregnated into the outer shell of the filter, giving it the ability to be able to trap bacteria as small as .22 of a micron.
A modern ceramic filter is very effective in filtering bacteria out of feed water, although there are a very small amount of microorganisms that are harmful to humans if consumed, the ones that are, if consumed can be fatal. The three basic groups are viruses, bacteria and protozoa.
Bacteria commonly maintain there characteristic shape. thankfully harmful bacteria such as shingella and salmonella are few in numbers, therefore reliance is placed on bacteriological testing for the testing of such organisms.
coliform bacteria such as ecoli are fairly simple to isolate as are present within the faeces all humans and warm blooded animals and as such appear in large numbers within sewage treatment plants. These kinds of bacteria can easily be filtered with the use of ceramic filtration.
Viruses can be filtered from feed water through adsorption by means of filtering out particles that viruses have attached themselves to.
Cryptosporidium and Giardia lamblia, potentially causes the greatest health risk than all the other microorganisms as they are resistant to chlorine, heating, freezing and also UV light. However because of the relatively large size of the cysts both these organisms can easily be eradicated with the use of a ceramic water filter
Additional filter media can also be added within the shell of a ceramic filter giving it the ability to be able to remove other contaminants chemicals, lead and bad smalls and odours. Ceramic water filters can offer an economical means of producing clean potable water.
