Ceramic Water Filter Effectiveness

Ceramic filters are quite effective at removing bacteria from water.

Ceramic water filter effectiveness.

Under laboratory conditions ceramic water filters were found to yield 3 4 log e. All ceramic water filters work in the same manner some personal size ceramic filters come with a pump that helps force water through the pores. Most ceramic filters are effective at removing bacteria and the larger protozoans but not at removing the viruses. Ceramic filters rid water of about 99 of pathogenic bacteria including e.

Ceramic filters are a natural way of filtering water but are they effective enough. Filtration test were performed gravitationally by flowing well water into ceramic filter. And vi cwps in field use were susceptible to recontamination through. Field experience with the ceramic water purifier cwp in cambodia.

Field trials of the effectiveness of ceramic water filters in cambodia over time showed a 46 reduction in diarrheal disease between filter users and non users a 95 1 average and up to 99 99 reduction of e coli in drinking water brown and sobsey 2006. This dissertation describes laboratory. Laboratory testing has shown a 90 99 reduction in viruses brown 2007. Ceramic filters are no novelty in the water filtration industry they have a long standing history of being used as a filter media thanks to their effectiveness in removing bacteria turbidity viruses protozoa cysts and other contaminants.

Filtered water quality was complying with indonesia drinking water quality standard e coli and turbidity. Coli shigella and salmonella. Studies have shown adequate removal of bacterial pathogens in water filtered through high quality locally produced or imported ceramic filters in developing countries. Ceramic pot filters cpfs represent an effective and sustainable technology for poor communities but the characterization of cpf lifetimes is on going and the water production seems to be the limiting factor.

Unable to pass through the pores the bacteria are filtered out as the water seeps through the ceramic filter. Iv filters maintained effectiveness over long periods up to 44 months in field use. In ceramic water filter clean water technology the pore spaces in the porous ceramic filter element are small enough to trap anything bigger than a water molecule. Ceramic filters have plenty of advantages but a few shortcomings too.

10 6 cfu ml passed through the filters independent of filter history. Few bacteria are smaller than one micron in size. Poor water quality is a major contributing factor to disease in developing countries. Porous ceramic filter coated with colloidal silver ceramic material provides physical filtration silver acts as a bactericide filter pot set in a plastic receptacle to store filtered water.
