When you are enjoying pure water, have you ever thought of people in remote villages and towns, who have no clean source of water, who are suffering from the lack of pure water to drink? Then, the public waterwheel filter design may be a perfect solution for this lack. The design is cleverly based on traditional waterwheel and modern water filtration equipment, whose principle is that the water from the bucket will continuously promote water to the waterwheel and clean the dirty water by the pressure of the water flow. Thus, not only the purpose of drinking clean water is achieved, but also there is no other energy needed.
