This involves modification of Titanium Oxide by incorporating other metals into it. Taking small portion of the mixed compound and incorporating it to the clay, molding a pot like filter out of it, drying and burning at high degree. When cool the clay pot is placed on top of another pot or bucket and both placed in the sun where the energy released kills the micro-organisms or reduces the metal ions. . Titanium oxide ...more »
The ancient African families preserve water on clay pot,But the cleanliness of the water preserved by that means are undermined impurities.For clean water to be accessible to African communities through the old way of molding clay pot;will be replaced by using Gypsum soil called POP as plaster of Paris,that has been used in medical treatment which will be baked with water treatment compounds like chlorine . The ColdFusion ...more »
Due to increasing water quality issues in SA one will have to start looking at medium and small water purification solutions. I propose looking at Solar powered water purification solutions. These units are extremely rugged, low on maintenance and very effective. All you need is a Salt water, brackish water or freshwater source. You basically dump the borehole pump in the water source, open the solar panels and switch ...more »
The presented proposal is a conceptual approach using a unique method to desalinate water and generate electric power at the same time, using a Hydromagnetic Dynamo. The Dynamo theory offers a mechanism of operation by which astrophysical bodies, like the Earth and the Sun, generate their own magnetic fields. A Dynamo, in its simplest form, is an electric generator. In this proposed technology, we use a Dynamo to desalinate ...more »
Solarsphere is a sun powered water distillation device that is designed to sit on a body of contaminated or salt water and produce a continuous stream of pure distilled water. It has no moving parts and requires no external energy source.
It is a winner in the " Next Great Canadian Invention" contest of 2006.
ECDI is a hybrid of two existing technologies that kills bacteria and purifies water. Using this technology means manufacturing costs can be kept at a minimum allowing mass production. The technology will be housed in a robust 10 liter water container that runs on a 9 volt battery source, thus allowing a means of water purification using whatever water sources are available at the time. The technology is also capable ...more »
I have made a lot of research as concerns clean water solution. There are a lot of solutions to providing clean water to the community but since most of these communities are poor it is always difficult to install the clean water systems or maintain them. A bio-sand water filter is a simple technology which is well suited for developing countries where other clean water systems are not available. These systems cost approximately ...more »
In most parts of Africa there are no installed portable water systems. In a case of emergency or in these remote areas where instalaton of a water plant is difficult, because of technical limitations, surface water filtration systems are a viable option. The LifeStraw® Personal, for example, is a portable water filter which can be carried for easy access to safe and clean drinking water. This water filtration system ...more »
poverty , water pollution and unemployment are the most serious problems in our planet . the water pollution is the most serious one not just the fresh(drinkable) polluted water which cause too much diseases and affecting badly on our health and our lifes but there is also the marine water contamination which causing the death for the aquatic organisms and decrease the water bodies productivity which would lead us to ...more »
Fun Fact Wedu is Shona for "OUR" Introduction into the project Wedu Water project seeks to solve three problems at once. These problems are (in no particular order); - Access to clean water is a challenge especially for people based in rural Africa, more specifically in rural Zimbabwe - In rural areas women tend to drop out of school because of poverty and social factors which means they cannot get jobs or become ...more »
clean water is expensive to provide.this is because it entails different processes involving huge chemical purchases.nature has bring this low cost method for rural dwellers and third world countries that liove on less than 2 dollars per day.it involves phase processing of water from sedimentation,filtration to purification using a mixture of moringa and calliandra roots grind together and held in position by semi- permeable ...more »
STAGE OF DEVELOMENT: PILOT PITCH Water covers 70% of the planet earth with 97.5% being salt water. However, out of the 2.5% of the fresh water remaining, 75% is locked up in ice and snow, leaving only 0.5% in a liquid form. Water is a basic essential commodity for life. It is also the most important factor in food production, cooking, personal hygiene, sanitation, industrial production, energy generation and economic ...more »
