Hydration for Health from an Early Age – How Ceramic Water Filters Can Help

Hydration for Health from an Early Age – How Ceramic Water Filters Can Help

Hydration for Health from an Early Age Water is one of the most essential nutrients for health, and yet many developing countries still have vast numbers of the population who do not have access to fresh clean drinking water. Water that is contaminated by bacteria can become, rather than a lifesaving ingredient, a cause of disease and even death. Although there are various initiatives around the w...
Firing Temperature and Shrink Tests

Firing Temperature and Shrink Tests

Test tiles 2cmx10cmx0.5cm     The first round of tiles for the filter clay temperature and shrinkage tests. Over 60 tiles to test at 925 950, 975, and 1000 degrees Celsius. We were sent between 250 and 500 grams of each sample, which turned out to be a little small. It took 100grams to make 4 tiles 2cmx10cmx5mm thick. and each time the particle analysis test was preformed we used 100gram...

2012 Year End Activity Report

Field Work: UNICEF Feasibility StudyBurt Cohen was sent to East Africa to study the feasibility of developing additional ceramic water filter production in Kenya. Burt visited the Turkana and Garissa regions and uncovered valuable information for future water filter projects in the area. We have partnered with UNICEF and other NGO’s in the region to expand production of CWF, such as the Rwan...
What Makes an Efficient Ceramic Water Filter?

What Makes an Efficient Ceramic Water Filter?

An important but brief study was published last year by individuals working with the RDIC factory in Cambodia to find what factors make a more efficient ceramic water filter. In this study several empirical tests were preformed to investigate the relationships between filter mix ratios and firing schedules. Perhaps the most relevant results demonstrated by these tests demonstrated the lack of corr...
Particle Size Distribution Analysis for Ceramic Pot Water filter production

Particle Size Distribution Analysis for Ceramic Pot Water filter production

Maria del Mar Duocastella and Kai Morrill Potters Without Borders, Enderby, British Columbia, Canada – September 2012 Abstract: To develop a standard Particle Distribution Analysis testing protocol for use in Ceramic Pot Water Filter factories. Introduction: Ceramic Pot Water filters are generally manufactured from sources of raw clay that vary in their consistency, some factories have begun...
The Importance of Local Investment – Ceramic Pot Water Filters

The Importance of Local Investment – Ceramic Pot Water Filters

As filter technicians we are uniquely placed to have a broad perspective over filter development issues. We facilitate the information exchange which happens between the several entities involved in research, development, funding, training, manufacturing, marketing, and dissemination of Ceramic Pot Water Filters (CWFs). Each of these areas requires targeted efforts in order to develop a solid and...
The Difficulty of Improving Simplicity – Ceramic Water Purifier

The Difficulty of Improving Simplicity – Ceramic Water Purifier

Rudimentary Ceramic Water Purifier (CWFs) were originally manufactured by hand with the same basic materials used in current models. These filters were hand formed from a mixture of minimally processed local clay combined with a burnout material such as pine sawdust or dung. Efforts by early CWF technicians Ron Rivera, and Fernando Mazariegos working with the Asociacion Guatemalteca para la Famili...
Batch Consistency – Ceramic Pot Water Filters

Batch Consistency – Ceramic Pot Water Filters

At Potters Without Borders our focus is on the transfer of skills required to manufacture strong, effective ceramic pot water filters. Manufacturing filters as an appropriate technology requires the utilization of locally sourced skills and raw materials. For technicians, the main challenge is to go through the process required to develop a working filter body within a short time, using greatly va...

Funding existing factories – Ceramic Pot Water Filters

Organizations seeking to effect positive change in health due to water borne disease often consider Point Of Use (POU) treatment systems to be the most effective method to reach rural communities. These organizations work locally, or internationally in various other aspects of assistance including health, education, and childrens aid. Once basic research into Ceramic Pot Water Filter (CWF) techno...

Letter from the president 2012

  Six years ago I and a small group of individuals founded a Non-Profit organization which has the primary goal of expanding access to clean drinking water around the world. We do this specifically by fostering the development of all aspects of ceramic pot water filter technology. Our organization collects and disseminates information and resources from technical consultants, academics, funding...

Oita Press article

Yesterday (2/19) I met up with an old friend here in Oita (Japan) who works for Oita press. We spoke for well over two hours he was interested in our water filter research and my Japanese newspaper class I prepared in China using their newspaper and their video site. I referenced both the English and Japanese/Chinese PWB websites. I am not sure when the article will be published but it may lead to...
