CT Filtron is a household ceramic water filration system distributed in Ghana.
CT Filtron are silver enhanced ceramic ‘pot’ water filters for point of use drinking water treatment manufactured in Ghana based on the open source technology promoted by Potters for Peace.
Target SDGs
SDG 6: Clean Water and Sanitation
SDG 3: Good Health and Well-Being
Market Suggested Retail Price
$13.00
Target Users (Target Impact Group)
Household, Public Sector Agencies, NGOs
Distributors / Implementing Organizations
The International Committee of the Red Cross, UNHCR, International Office Of Migration, GIZ-Integrated Water Resources Management Project; CARE International; Social Fund for Development, ADRA, Partner Aid International.
Manufacturing/Building Method
Locally sourced clay and sawdust are processed then mixed with water, pressed into the filter shape, fired to a ceramic state, flow rate tested to ensure production consistency and coated with silver nanoparticle solution.
Intellectural Property Type
Open-source
User Provision Model
From local distributor, accredited distributor in Accra or online retailer.
Distributions to Date Status
More than 10,000 units
Design Specifications
The CT Filtron filtering element is made from porous clay that removes particles and bacteria from water. The ceramic filtering element is also treated with silver nanoparticles.
Technical Support
Technical support is left to the users. When filters clog, users must scrub ceramic filtering element with a brush.
Replacement Components
Replacement pieces are available through a local CT filtron distributor.
Lifecycle
3 years
Manufacturer Specified Performance Parameters
Performance targets: removes Guinea Worm, Cholera, E. coli and other common pathogenic bacteria. Bacteria reduction of >2 log and 2-4 liter per hour flow rate (when full).
Vetted Performance Status
Test results from the Water Research Institute of the Council for Scientific and Industrial Research (CSIR) Ghana indicate elimination of Guinea Worm, Cholera, E. coli and other listed bacteria. The results from Dept. Of Microbiology, University of Ghana Medical School indicate that the CT Filtron is effective in removal of pathogenic parasitic protozoa, other macroscopic organisms and debris from water. CT Filtron removed 99.5% of total coliform when measured by membrane filtration.
Safety
Unknown
Complementary Technical Systems
Pre-filter for turbid water (> 5 NTU).
