Filtration and adsorption for water purification

Problem: Water pollution is a major challenge throughout the world. The challenge of water in Africa is linked to health, power, energy and the economy. The purification of water might help minimize the above mentioned challenges, giving us a second chance to build a better economy. Few people in the continent have little of no access to purified water and thus rely on the wells and dams for freshwater for domestic use. ...more »

Sustainable Use of Underground and Rain water

Water is one of the essential compounds for life and a scarce resource in the same measure. It’s said that this essential commodity occupies almost 75% of the earth’s surface but it’s quite ironical that with this kind of abundance water would still be referred to with an adjective like scarce or even the word drought should exist. Ironical or not, there is no sufficient fresh and clean water for consumption. Most of ...more »

LOW-TECH DEWATERING TECHNIQUES.

It is standard knowledge that the continent of Africa comprises mostly developing nations and hence the continent is a massive site for construction and large scale mining activities. But these activities does place our immediate environments under siege to a few hazards such as soil erosion and man-made flooding. In this regard, the main culprit of damage is WATER. Water that could have been made available for a variety ...more »

Aqua-Cura Mobile Water Sterilisation unit

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 »

Aluminium Sulfate ( Alum )

Aluminium Sulfate ( Alum ) For many decades now aluminium sulfate, or alum, has been the standard raw material of the water treatment industry. Its large molecular size and weight, combined with low cost, make it an excellent flocculant for the treatment of both drinking water and industrial waste water. In addition to water treatment, aluminium sulfate finds use in a diversity of other areas including construction products, ...more »

MORINGA WATER PURIFICATION

Moringa seed powder can be used as a quick and simple method for cleaning dirty water. Studies show that this simple method of filtering not only diminishes water pollution, but also harmful bacteria. The moringa powder joins with solids in the water and sinks to the bottom. This treatment also removes 90-99% of bacteria contained in water.

Delivering the right quality of water, sustainably

All over the world, even in developed countries, the water supply infrastructure aims and struggles to deliver (expensive) high quality water to consumers but most of the water is then used for uses that do not need such a high quality of water. For example, it is not necessary to use drinking water to wash. A clean, though not necessarily potable supply of water will suffice for these uses. However, people still need ...more »

WATER DESALINATION USING A DYNAMO.

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 »
