Water Sources in Africa and particularly in Uganda are; 1. Clear flowing water and 2. Lakes, ponds and rivers Clear flowing water coming from somewhere without people, manmade things or an obvious sign of pollution is best. Lakes, ponds and rivers are less ideal. The first two are stagnant, which may mean increased levels of bacteria and other gross things, while large rivers are typically full of pollution. Not forgetting ...more »
Everything-but-the-sink portable filter This portable filter design proposed in response to a call for better water filtration at taps in India uses chlorine, silver beads, activated charcoal and sand. Honeybee Network posed the original problem and an E4C member posted this solution. It includes a detailed guide to the specifications, materials and construction of a portable filter built from everything but the kitchen ...more »
Slow Sand Filtration (SSF) technology has been used to treat the drinking water of many European and American cities over the last 200 years. Introduction of slow sand filtration to American cities in the early 20th century was the primary factor responsible for the massive declines in infant mortality and waterborne disease. The HydrAid Biosand Water Filter is the inspiration that is the solution. Performance, life saving ...more »
Bamboo charcoal In this spin on the charcoal filter, a team of E4C members in Bangalore propose a filter made of locally available materials including charred bamboo, gravel and natural adsorbents. "The process we propose is indigenous, eco-friendly, low cost and entails minimum maintenance," the team writes in their workspace. They estimate that their filter can handle 30 liters of water per hour, and it would be affordable ...more »
This is a project I am currently working on for my Chemistry Honours degree. Using a clay-polymer nanocomposite for water filtration. It is well known that clay is a very abundant material especially in Africa, and it is also very cheap commercially.In comparison to activated carbon, clay is actually 20 times cheaper. Naturally clays are non-toxic and have very good adsorbent properties because of their already existing ...more »
5. Filtration: How can we turn available water into drinkable water through filtration?
We can use safe guard, other tablets that can just be dropped in a clean water can to filtrate the water.
Using nature's genius and systems thinking to achieve zero waste within informal settlements. We have used the principles and genius of nature to develop an effective solution that addresses the impacts of stormwater and solid waste from informal settlements; piloted in two projects for the Berg River Improvement Plan in the Western Cape. The end goal is to achieve a zero-waste scenario, ...more »
Despite few privilege persons in South Africa, who are able to spend on clean water others does not enjoy the right of clean water . Simply because ‘ they do not have access to a cheap, easy, method of filtering water .’ What I suggest, is a virtually, zero cost practical method which could use to filter water and purify it. Historically Boiling water is considered as the cheap, low cost, and practical method of cleaning ...more »
Many areas in Africa have seasonal rainfall the simple construction of Dams , using clay from termitè mounds , these are found in most places , any seasonal streams can be ďamed using simple farm tools, a channel is thèn ďug , a perforated plastic pipe installed , covered with gravel 15 centimetres , toped with clay .The result çheap construction , clean water !
The Lifestraw is a small cigar-shaped tube packed with some truly innovative engineering. This clever design purifies water from potential pathogens like typhoid, cholera, dysentery and diarrhea – all before they reach your lips. The Lifestraw is an inexpensive way to deliver potable water to those in need, and it is considered an icon of humanitarian product design – it was included in Cooper Hewitt’s Design for the ...more »
this is a three step natural process of filtering water which is zero cost and 100% practical to any citizen in the world.
considering the economy , environment and availability of water and other resources in south Africa this process will be the most suitable method of filtering water in almost all the areas of Africa
water sourced locally contains dust particles and other free radical elements similar to iron oxide of rusted galvanized pipe use to deliver pip born water and storage tanks. The use of chlorine to treat water as a halogen element is to kill pathogens like bacteria and micro organism in the water.
