What's the news on this project?  Is it still underway?  Most of the comments are from years ago.

I agree with Sam Au, silver is a great antimicrobial agent, any ideas on how to implement it into the scale this project needs.  Maybe some voltage running through silver rods at the villages main water store?

Also has anyone considered Zeolites?

Hi all,

I'm new to Science for Humanity and would like to get involved in your projects!

It looks like you are looking to use UV or chlorination to eliminate bacterial contamination from your drinking water? Have you guys considered silver as a solution? Silver is a strong anti-bacterial/fungal agent which doesn't require a replenishment or energy input to operate so it may be a cheaper and simpler alternative. I've attached links to a couple peer-reviewed articles:

At present I am doing research on water resources Management (River Bangshi) at Savra, Dahaka, Bangladesh. The water of this river is being polluted from 1990s when massive industrialization take place at Savar, near Bangshi. Now agriculture is being hampered, traditional occupational groups i.e fisher men groups are lose their profession as there are no fish in the river. local health is affected. Further ground water going down every year. 

Imminently I am looking for how we can purify this water so that we can offer it the polluting industries who are discharging their waste directly to the river. In addition to search for effective management system.

I would like to request a copy of detailed guide on how to build such a system. Recently we discovered that our water source in our schools is not safe for drinking and I'm looking for a cheaper appropriate technology that can be applied to rural areas where our school is located.

Hi Rafael,

Yes, we are still considering chlorination column but before that Pao is trying to get some analysis completed. We have identified a few researchers in Thailand who might be able to visit the village to observe the situation and to provide input. But before we consider the potential solutions further, we need to determine how much chlorine is in the water, the retention time and levels of E.Coli. Once we have this data then we are arrange another meeting to discuss the treatment options.

Thanks,
Anu

Hi, here are some factors to consider before using slow sand filtration, and other information as well:

Hello, Many thanks for the links Michael, they have good info. I will also try to watch the film.
Thank you Anu for your idea, I think slow sand filters are a very good option of all the posibilities. I will read more about this and get back to you. Are you still considering the addition of a chlorination column?

Hello members,

Just recently I was speaking with Dr. Kristof Bostoen about our Thailand Water Project and their WASHCost project. He recommended using slow sand filters to remove E.Coli from the water filtering and purification system build by the Pao and his team in Thailand. Dr. Bostoen thinks that slow sand filters are efficient, but unfortunately, not used as widely, and that it might be labour intensive, but would be a cheaper option.

What do you think?

My best,
Anu

Check out the movie for the Academy Awards this year, "FLOW" http://www.flowthefilm.com/filmmakers
Also check out: http://www.thewatergeeks.com/About-WaterGeeks-sp-2.html
Soon all the world water will be controlled by the non thirsty if we do not watch it. The world must come together and make a declaration of water rights for all humanity or it will be sold to the highest bidder and kept for black mailing us all. The movie flow is of great importance to all of us as well as climate change. To own a jvc 100 video camera and a macPro computer to make documentaries is the tool of allowing the most brains to obtain data in the world. It is every human beings duty to try and win an oscar now to help humanity make it ever more propitious for humanity.

The little wonder does 160 gallons to 200 gallons a day, if you have 2 or three of these then if one breaks the others are going, they work on sun, wind and are many boats all over the world now. Excuse my spelling some times i hate to proof read. I think and tink. :-) it's the thought contexts that count, for give me. The little wonder is the name of this water maker for boats use the most.
This would give you with 3 of them, about 600 gallons a day for 200 houses or about 3 gallons per house hold for drinking. Maybe you need 6 of these, but to have more stops from having all your eggs in one basket. The high pressure pumps go out some times etc. they do work or people die on boats, so serious.
