Explain your project in details:

Water is essential in our everyday life, used in almost every domestic activity, from cooking to washing or for sanitation. Water availability is neither adequate nor equitable for all human beings. In addition to the problem of limited availability of water, there is also the problem of water quality. For instance, the biological and chemical contamination of water is a matter of grave concern. One such chemical contaminant present in the water is fluoride. Exposure to fluoride can give rise to several adverse effects. These range from mild dental fluorosis to crippling skeletal fluorosis as the level and period of exposure increases. Taking health effects into consideration, the World Health Organization (1996) has set a guideline value of 1.5 mg/1 as the maximum permissible level of fluoride in drinking waters. In contact with water bone charcoal is able, to a limited extent, to absorb a wide range of pollutants such as colour, taste and odor components. Moreover, bone charcoal has the specific ability to take up fluoride from water. Where one or both the hydroxyl-groups can be replaced with fluoride.From initial assessment bone char has proved to be appropriate under all social, financial, economic, environmental and technical conditions. I designed a working prototype for fluoride de-fluoridation utilizing bone char. I'm looking for funding to further develop the concept and implement it in rural communities which rely on ground water consumption for their drinking water. The advantage of this technology is that,the bone char can be regenerated after saturation, hence economical, also raw material such as bones are readily available in the communities.

Impact of your enterprise on sustainable development

The most common manifestation of over consumption of fluoride is by dental fluorosis. This is characterized by browning and mottling of teeth. It is visible by white, yellow, and brown streaks on the teeth, characteristic of the hypoplasia and hypo calcification. This damage is more than cosmetic, as it tends to be associated with painful cavity like feelings. Additionally, there are social stigmas against those suffering from fluorosis. The use of innovative technique, which employs bone char for de-fluoridation of drinking water. The innovation in regeneration of bone char makes the technique cost effective. In addition, equipment will be easy to operate with minimal technical knowledge. Mitigation of fluorosis among inhabitants of remote communities which consume underground water contaminated with high levels of fluoride. The utilization of bone char in de-fluoridation of drinking water in this communities is economic because there is no daily addition of chemicals hence, no sludge disposal into the environment compared to other de-fluoridation method. The water de-fluoridation process utilizing bone char has shown to remove fluoride ions at cheap cost ( USD $0.40 per cubic metre of water) compared to other technologies such as membrane filtration, etc.

Sustainability and future plans

Developing a system that is sustainable to rural communities is of paramount importance. The cost of the treated water must be economical to low income earners and the poor. Also the process must be able to sustain it self to keep on running providing safe water to communities without government funding in the long run.

Hello fellow passenger,

You might have heard the famous song "What I've done" by Linkin park. The lyrics have been beautifully carved by the late singer Chester Bennington. The song covers the ways in which our so called development has helped only a handful of the upper society members, whereas people are still living in poverty.

We have a great platform here which is urging super brains from around the world to come together and collaborate with their ideas and help make this world a better place to live in. You have been a part of this community and I congratulate you on your effort that you have put in.

Thanks once again and all the best for the future

Comrades,
In this fight for a sustainable future, what we need is innovation; something which is not necessarily new, but which makes us look at things from a different angle.

I believe this is one of the major motives of this community which we are a part of. Taking one step together hand in hand towards our goal is the only way we can achieve it.

So I wish you the very best in this endeavour of yours and hope to see you together in the new tomorrow

Dear Fellow participant,

You have done well thus far. Only few people will venture relentlessly into the things in which their instincts proposes because sometimes the goal appears too crazy to achieve, so they just retreat.

Actually, someone has said that "The people who are crazy enough to think they can change the world, are the ones who do."

You may have seen this before but I want to remind you that it's true, only those who are "crazy enough" eventually get results.

Congratulations for been "crazy enough" (seeing beyond normal and following your dreams despite the odds)...

Best wishes,
Seth
