As of June 2008, IDE Cambodia has manufactured and sold more than 100000 affordable ceramic water filters. These filters are manufactured locally in Kampong Chhnang with Cambodian clay and rice husks. Coated with colloidal silver, they have been proven to remove 99.9% of harmful bacteria from any water filtered through them. Cost: $8 This video was produced as part of a social marketing effort to inform Cambodians of the benefits of the “CWP”. It was broadcast on two Cambodian national TV …

Where can I buy some of these in America?
Love it! its an amazingly simple idea! WOW
Can you introduce this product to Vietnam in the near future?
We’ve introduced a slightly different model in Nepal more appropriate to the region. The trick is to find local resources and motivated local people in whatever area you’re considering. That’s the best way to make these products and enterprises sustainable. In Cambodia, we had (the late) Ron Rivera of Potters for Peace visit the region and help us ID a traditional pottery-making village with access to local materials and the knowledge to work it properly.
Wonderful! Has IDE introduced this to any other countries? This could be a great technology for Eastern Africa.
awesome. Social entrepreneurs making a difference.
The micropores are actually created because rice husk (recycled from milling) is mixed in with the clay, and is then burned off during firing. So, the pores remain where the rice husk was in the mixture. The clay used in our CWPs in Cambodia is sourced locally. As you can see in the video, the soil in that region of the country is red clay.
This sounds like a potentially great idea. I have seen viable, small-scale sea salt harvesting in Ghana from rock collection. Connections to Europe are better from Middle East and North Africa, and that’s where desalination is making economic sense. If it’s small-scale, municipalities benefit directly.
For salt harvest, maybe pipe is actually an open trough (like Mediterranean roof tiles), but covered with more tiles for good sanitation.
immense need: i was referring to the way the US has found that the chemical fields, after a few years, deplete their micronutrients so then the produce can contain half the vitamin content of previous crops.
sea goods have ALL the micronutrients due to they wash down with land run-off.
the clay sounds like a great way to cheaply desalinate water. pipes of it could be seeping ON THEIR WAY to arid regions. a LONG green strip. or double wall it with an impermable so it can seep on the way and let to side pipes.
salt may be harvested as well, possibly lucratively due to the popularity of sea salts.
to seperate the minerals from the salt< <HEALTHY due to immense need for chemical fields to have an easy way to replenish micronutrients.
THANK YOU FOR THE REPLY.
collodial silver. a cheap source is two pieces of silver in water; each piece is clipped to a wire with electrical voltage going to it.
do you have info as to minimal amount of silver needed? or is there a threshold where it becomes harmful?
re the micron size, do you know if most world clays have the capacity to bake those sized pores/be effective?
Yes. The water is filtered through the clay filter element by gravity and in the process, passes through the colloidal silver coating on the clay filter. The micropores in the clay element filter particles down to 2 or 3 microns. The silver coating kills bacteria smaller than that.
wow. cool. does the water soak through the silver?
