Using the sun to purify drinking water is a great solar project for the do-it-yourself. A solar-powered purification system the size of a microwave oven can yield up to 3 gallons of purified drinking water on a sunny day. Here’s what you need for a basic solar powered water purifier like the one shown in the figure: Wooden or sheet metal enclosure Reflective material like aluminum foil Black paint, used for barbeque ...more »
Basic concept: What is distillation? The action of purifying a liquid by a process of heating and cooling Therma Energy:Form of heating by employing electric heating or fuel burning or solar heating Solar Energy: Solar radiation is a form of renewable energy that is abundant and accessible in many areas in the world.Sunlight with wavelengths of 315-400 nanometers (nm) on the ultraviolet (UV) range of the electromagnetic ...more »
The main source of drinking water must be protected from deliberate pollution and spread of disease like guinea worm. The water is shared with animals, and is used by humans for cooking and drinking in the villages of Africa. Our solution to this program is to integrate a Sun-powered Water Well into the villages of Africa. This Water Well is eco-friendly and environmentally safe. As opposed to similar Merry-go-round ...more »

After discussions with a colleague with extensive experience in ground water research and borehole pumping projects, I learned that ground water extraction by means of solar powered borehole pumps have been proven quite successful in providing a considerable quantity of fairly clean, drinkable water to farms and rural communities. It is also a fairly simple system that works independently, requires little maintenance; ...more »
An Australian company, F-Cubed has designed a magnificent portable Solar Water Purification and DESALINATION plant that has no mechanical parts or filters to change.
Simply pour in water in the one end and clean water comes out the other side... up to 20 liters a day can be desalinated.
My name is Adrine and i have good experience in the water business or sector and in my view (and if any one disagrees please give me a strong reason) there is no way Africa and for examplw Uganda in particular will ever meet the MDG goal 7c if we do not consider water purification using solar. We all know that electricity is still a chsllenge but we have the technology right infront of our eyes but we ignore it. well ...more »
This method involves the construction of a borehole with a pump that uses solar energy to power it. The pumped water is plunged upwards into a reservoir tank after passing through four ultra filters which are installed near the tank. A small tap connected to a pipe coming from the tank is used for easy access of the water. The ultrafilters ensure removal of disease causing pathogens before the water enters the tank. this ...more »
CAROCELL™ Direct Solar Powered Desalination Technology is one of the most efficient and cost effective product of its kind in the world. The panel(s) system creates its own natural sun-powered water cycle to revitalize water to drinking water quality from any water source. This includes polluted, contaminated, industrial waste water, brackish ground water, saline aquifers and sea water. Pure clean drinking water from ...more »
This simple technique requires only a few plastic bottles and sunlight. Firstly, collect several bottles (0.3 to 2.0 litre) made of clear plastic, remove all labels and wash them thoroughly. Fill the bottles with water of low turbidity and shake for about 20 seconds to aerate the water. Expose the bottles to the sun by placing them on a roof or rack for at least six hours (if sunny) or two days (if cloudy) . The water ...more »
Solar water disinfection (SODIS) involves exposing water-filled plastic polyethylene terephthalate (PET) bottles to sunlight for several hours. Exposure times vary depending on weather and climate from a minimum of six hours to two days during fully overcast conditions. Principle of proposed container action This method uses a conical container with a large closure lid fitted on to it a convex lens(the convex lens is ...more »
We can very well see that there are some areas in Africa that has rivers but lack the means to connect these rivers for the use of its water in house holds and farms. This is because they lack electrical power to aid in the activity. Solar water systems use the power of the sun to drive a submersible electric pump and are ideal for boreholes with a high yield. The pumps I am setting on is the - helical rotor pumps - ...more »
