Kenya Feasibility Study Trips ■Aim: Improving access to safe drinking water and contributing to the nation’s adaptation measures against climate change by introducing our new solar-powered electrolysis water purification system
■ 1st Feasibility Study Trip: 26th August – 8th September 2012 Location: Nairobi, Kitui, Kisumu, Mombasa
■ 2nd Feasibility Study Trip: 21st October – 28th October 2012 Location: Nairobi, Nakuru
1. Borehole / well water contain harmful substances. Water in the Rift Valley regions contained high concentrations of Fluoride, and in the other regions, typically high salt containment.
2. Approx. 70% of national diseases in Kenya are related to water problems.
3. No dominant and effective measure to counter this issue is recognized by the government.
4. Need to propose an acceptable and affordable system cost in consideration of people in need for water.
5. Kenya government is highly aware of the issues, and are interested in our activities.

■Conclusions of 1st Trip: In the areas other than Rift Valley, salt concentration is a more serious problem than fluoride. Sharp will develop a system to purify water by basically using filtration to remove the salt, and kill the bacteria by the electrolysis device
Confidential 9
Result of 2nd Trip ①
If water has very little fluoride, the color stays red
High concentrations of fluoride, over 3mg/L, well over the WHO Drinking Water guideline (1.5mg/l)

■Aim: Typical problems in Rift Valley confirmed by our 2nd trip delegation Partly the fluoride containment seems to be excessive
Confidential 10
Result of 2nd Trip ② ■A lot of potential demands in Nairobi for industrial applications 1. Unreliable municipal water supply 2. Development of boreholes costs extra electricity required for pumping and treating the water. 3. Water and electricity cost is a common big problem among the factories and companies in
Nairobi. 3. Using the same technology, our system can be adopted in industrial application to minimize all
the related costs.
■Conclusions of 2nd Trip: In the areas of Rift Valley, fluoride is indeed a serious issue and this problem must be solved through a system of a reasonable cost. Sharp will also develop the system to remove the fluoride using electrolysis technology in a special way to purify the water by filtration (modification is necessary from the one developed based on 1st trip result)

Borehole Water Sample from Special Hill School, Nakuru
1) Water quality test using UV
2) DB-6 Type Electrolysis Test Took 50cc out of 440cc of the sample and carried out 15 mins.of electroysis with an electric current of 12A/dm3. (50cc = 1 unit)
3) Coagulation and Sedimentation Measure fluoride concentration by adding aluminum sulphate to the 400cc sample.
Fluoride after coagulation and sedimentation will be processed by 0.1μm membrane

■An example of a new business mechanism
Different functional water can be produced. If the demand grows, the system can be easily customized and expanded to meet the demands.

Industrial Application (Effluent Treatment) ■Many track records in Japan (restaurants, hospitals and swimming pools). ■We expect a growth in demand for effluent treatment. ■700 companies are members of the KAM (Kenya Association of Manufacturers).

Conclusion
● Solar+Electrolysis would contribute to countering Kenya’s water issues. ● Support in the form of ODA may still be required since locally there is still lack of funding. ● Japan’s technology can contribute to the industrial development, employment-promoting, and economic development of Kenya. ● We aim to build a long-term, mutually complementary and amicable relationship between Kenya and Japan.
We aim to counter water issues worldwide, and to contribute to industrial and economical development in various countries.
