Carbon Filtration machine

As Enactus Midlands State University and in partnership with Future waters Bulawayo we designed a machine that uses carbon filtration process to purify water. it costs US$850. It consists of a manual hand pump to reduce costs, aqua shield filter and granular activated carbon filter. We are looking for means to avail and increase production of such machines and probably modification of having the machine at a large scale ...more »

water project

The issue being that water is currently obtained in most villages by an individual tossing a container into a deep hole, and pulling out the collected water. Most commonly, the solution would include aid workers digging a well in a densely populated village, and attaching some rendition of a lever-action pump to the enclosed top surface. Unfortunately, this approach dwells a number of problems, including its financial ...more »

Purification and Filtration of Water

Water is carefully collected and received through stainless steel pipes from either a local well or municipal water supply. Quality testing of the original source is conducted regularly to monitor for abnormalities. This step is taken when the water originates from a municipal or public drinking water system. It consists of removing chlorines and THMs (trihalomethanes) through a daily-monitored activated carbon filtration ...more »

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 »
