Ceramic Water Filters

Both the MK Kiln and the Ceramic Water Filters were developed by iCATIS’ Director of Research and Development, Dr. Robert O. Marquez. These filters are capable of removing turbidity and pathogens from source waters, and thus can be used to clean freshwater and rainwater catchment waters that are devoid of any additional contaminants. The filters are made with local materials found anywhere in the world, namely: clay, sawdust (or similar material), and a small percent of colloidal silver (for pathogen removal which is readily and inexpensively found in most markets). Each filter system produces approximately 24 liters of water/day, or enough drinking water for a family of four. The filters employ local labor and are currently produced in the MK Kiln at the CATIS-Mexico Institute. With minimal maintenance, the filters can reduce the cost of potable water from $0.10/liter (US $2/20 liters) to approximately $0.001/liter, or 100 times less expensive.

iCATIS’ own water performance testing has shown turbidity and pathogen removal to the no detect levels, using standard total coliform testing procedures. The filter is so effective, in fact, that it was tested against the worst case scenario - treating raw sewage water - and iCATIS found no detection of total coliforms in the filter effluent. Presently, iCATIS is working with Northern Illinois University (NIU) to compile their own, third party water performance characteristics data including turbidity and pathogen removal (i.e., as measured via total and fecal coliforms).

While the filters are being used to address water quality concerns in the state of Guanajuato, iCATIS is collaborating with various universities to expand the application of the ceramic water filters. iCATIS is collaborating with:

  • Northern Illinois University (NIU) to create an inexpensive filter ‘add-on’ that can be used to remove arsenic and fluoride from the groundwater, thus enabling application to the arsenic and fluoride laden groundwater in the Guanajuato region.
  • The University of Tamaulipas and Engineers Without Borders Mexico to develop 'add-ons' for petroleum, pesticide, and organics removal
  • New Mexico State University for uranium and other radioactive contaminant removal
  • James Madison University to assist in QA/QC procedures for approving fired filters for water treatment use

With these strategic partnerships in place, the goal is for the ceramic water filters to be applied nearly anywhere in the world to address any water quality problem that exists.  Please help to further iCATIS’ mission by donating money to expand the range of water quality problems that the iCATIS water filter can address.
