IDE Ceramic Water Filters in Cambodia

To better understand the processes that induce structural strength of these clay pot filters read

Physical Properties of Porous Clay Ceramic-Ware By A K Plappally, I. Yakub, L C Brown, W O Soboyejo and A B O Soboyejo , 2011, , Journal of Engineering Materials and Technology,ASME, 113 (3):311004-1-311004-9.

I use this at my house in capital city Phnom Penh, Cambodia. This product is the best. Long-lasting, economic, portable, it's just great.

Hi,nice to meet you.I am undergraduate student of University Technnology of Malaysia My name is Apple.I am impressed by your video of ceramics water filter.Can u do me a favor to provide me some information ?

1) what is the physical composition of the ceramics in term of percentage?

2)How long is needed for the baking of the ceramics and the baking temperature?

3)what is the percentage by mass of rice husks?

Pls contact me via gin_n_lemon822@hotmail.com.

How long does the silver treatment on the crocks last before it is depleated and the crock must be re-coated or replaced? How would you tell if the silver coating was worn out?

Where can I buy some of these in America?

[JoeProvence]

Love it! its an amazingly simple idea! WOW

[smilingstickman]

Wonderful! Has IDE introduced this to any other countries? This could be a great technology for Eastern Africa.

[IDEorg]

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.

Can you introduce this product to Vietnam in the near future?

[IDEorg]

jellofast: we are working very successfully now in Vietnam on design/construction of affordable latrines for households and communities. Good sanitation is the longer term lynchpin in community health.

awesome. Social entrepreneurs making a difference.

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.

[CakesPix]

wow. cool. does the water soak through the silver?

[IDEorg]

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.

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?

[CakesPix]

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<<<that may be extremely lucrative AND HEALTHY due to immense need for chemical fields to have an easy way to replenish micronutrients.

[robbman99]

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.

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.
