SHORT PROJECT DESCRIPTION:

The device is aimed to prevent the spreading of contaminated water diseases in deprived areas like Ghana or some places in India or some towns here in Iran or every other places which needs the safe water. This device filters and disinfects the water after storing it. It mainly uses solar energy as a main source and it needs minimal requirement to external energy sources; however it can use external sources of energy for starting up the process.

ADDITIONAL INFORMATION / REMARKS:

Purpose and summary of the project proposal: The functioning of the devices is based on receiving and storing dirty water. Afterwards water is passed through ceramic filter till all the bits greater than 0.5 μ are removed and the water is transparent. This process reduces most of harmful and poisonous parameters of the original water. Series of transparent drinking bottle made of PET(POLYETHYLENE TEREPHTHALATE) are connected and aligned and water enters the first bottle and then transferred to the successive bottles thereafter. In total all 20 bottle of 1.5 L will be filled with water. These bottles in a matrix configuration are places on inclined roofs which are covered with Al foil. The whole system is placed such that its facing the sun. In two ways the water in the bottles are decontaminated. First; heating of water by the sun diminishes many microbes and germs and also UVB and UV-C rays of the sun, in addition to killing of most of the harmful microbes, will actually decontaminate the water after 6 hours. So far, according to experiments, 80% of parameters causing illness has been removed and the remaining 20% is believed not to cause life threatening illnesses and most of them are believed to be destroyed in the body. However, we expanded this design and tried to accommodate the remaining 20%. The second stage involves usage of UV lamp in order to completely decontaminate the water. The needed energy is supplied form one Solarium Cell along with Voltage regulator and a battery. When the water passes this stage, almost 98% of the harmful parameters have been removed and the water now is completely clean and drinkable. In the last stage, this water enters a prism storage cylinder which its glazing is made of glass wool and its prism has a cut which exits the warm air and thus results in cool water in the controlled processed device. In the above stages, a foreign/ external energy provider was not used and all the energy was provided from Solarium cell. we use battries to restore the energy when we dont have sun light.
