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 »

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.

Micro-organical purification.

Water can also be purified at a low cost by the use of Chlorine which is highly electronegative and very active in the killing of microorganisms. These notwithstanding, some organisms have spores which might prevent them from intoxication by chlorine, in this case, Boiling is required which is not so effective but to a reasonable extent. Since the clean water need to be made available at a low cost. Thank you.

Ocean Water Purification for the World

The salty sea water covers 70% of the earth’s surface. 50% of the world population stays within 100km from the ocean shores. The reverse osmosis technology and similar technologies are well developed and tested technologies to purify salty sea water into drinkable fresh water. The problem is the costly energy / electricity needs to run these plants especially for drawing water from the sea at high pressure. This cost ...more »

Use of a Hamster Ball-Shaped Solarball

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 »

Chlorine or Iodine Treatment

Iodine is light sensitive and must always be stored in a dark bottle. It works best if the water is over 21 degree celcius . Iodine has been shown to be more effect than chlorine-based treatments in inactivating Giardia cysts. Some people with iodine allergy to and cannot use it as a form of water purification. Persons with thyroid problems or on lithum, women over fifty, and pregnant women should consult their physician ...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 »

Small to medium water purification solutions

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 »

Point-of-use method for mercury removal from portable water

The use of mercury in small-scale gold mining is polluting thousands of sites around Africa, with water bodies in the mining regions being highly affected such that the mercury concentration is far higher than the recommended 0.002 milligrams per Liter (mg/L) or 2 parts per billion (ppb). This poses long-term health risks to the inhabitants of mining regions as most of them directly consume the polluted water without ...more »
