We propose a circulation shower that saves 90% on water and energy. Families can shower endlessly with only a bucket of water. Our idea is to make an Africa-proof version of the circulation shower - a proven concept. This idea has already been deployed in the Netherlands and is ready to be deployed quickly on a large scale. By making circulation showers available to all families, schools and other public institutions, ...more »
Solar Thermal Pure Water Distiller(2) 1.Solar Thermal Water Distiller (STWD) 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 ...more »
Over the previous 3 years, we have developed a water sterilising unit that can destroy bacteria, viruses and hydro toxins, without the use of any chemicals. We then combined the steriliser with a filter that removes toxic metals from water. We have had extremely successful results that was analysed by WaterLab, an accredited SANAS lab. (Please note that this is not a reverse osmoses system). This combination was installed ...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.
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 »
Ugandans lack clean water for their domestic activities including agriculture, livestock, industries and others yet there is plenty of sources of water like springs, lakes, rivers and groundwater. The problem is not that there is no water, it is because people do not have ways of delivering water from sources to their point of use. So, the low cost irrigation project (Makerere University, CEDAT) manufactures solar water ...more »
SOLAR POWERED ULTRAVIOLET WATER TREATMENT DEVICE Introduction Ultraviolet or UV energy is found in the electromagnetic spectrum between visible light and x-rays and can best be described as invisible radiation. In order to kill microorganisms, the UV rays must actually strike the cell. UV energy penetrates the outer membrane, passes through the cell body then disrupts DNA stopping reproduction. UV treatment does not ...more »
Not to be confused with solar sterilization or disinfection, solar distillation purifies even muddy, salty or otherwise undrinable water through evaporation and condensation. The power of distilation to purify saltwater makes it unique among the treatment methods featured on this page. A solar still can actually be a cheap and simple piece of shaped plastic or glass, or they can be more highly designed devices. To work, ...more »
Developed countries are used to having a supply of fresh, clean water piped straight into their houses for their convenience. In some African countries, however, especially rural areas there isn't any provision for the supply of drinking water. Women and children take water from rivers or lakes and carry this back to their house, which is very labour-intensive. I'm not dealing with the supply of fresh, clean water here ...more »
Using the sun's energy to both use it to warm up water with concentrated lenses and in the same time using the same solar energy to drive the Photovoltaic panels to power an ozone generator to kill the bacteria
Also we need to know the total TDS total dissolved solids of the local water to see if water must be brought to boil
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 »
Designed by Jonathan Liow, a graduate student at Monash University, the Solar Ball is a spherical shaped device that utilizes the power of the sun to purify water. Inspired by a trip to Cambodia, Liow sought to aid underdeveloped populations that lack access to clean drinking water. When placed in the sun, the Solarball uses evaporation to separate dirt and contaminants. The resulting condensations yields just over three ...more »
