South Sudan Water Crisis
Why do the people of South Sudan need a water purification system? What is the biggest issue related to water facing the population?
Small Scale Solution
MethodBoil impure water, put the lid on the pot/container, so that the water vapor remains in the container.
Then wait for the vapor to cool and condense, which will leave behind pure water...
the only cost here is a container and lid.
tools to create fire if not accessible to community.
cost stays under 20 dollars, at maximum...
very cheap, very easy to operate
May not eliminate all microbes and bacteria on first try, multiple methods needed possibly
Large Scale Solution
find a water source
filter the water through a metal screen
put the filtered water in a settlement tank to let the remaining sand and dirt.
then add aluminum and lime... that causes the dirt to harden and then it can be removed easier.
add chlorine to kill microbes and bacteria
then check the Ph level with a Ph strip.
neutralize if the Ph is too high, and store the water.
most expensive of the 3 solutions, needs land as well.
while the metal tanks and screen are the most expensive, roughly around 1,200 for set of both
the chlorine isnt expensive and the Ph strips are inexpensive as well, 15 dollars at least.
the aluminum sulfate in bulk is 45 dollars and limes are cheap in bulk.
cleans water completely, and cleans a lot at a time
costly, and required outside resources that might to hard to obtain
Group of 20-30 people
purchase a water filter 30 to 40 dollars
buy carbon insert, ion exchange resins and silver tablets
insert water, and let the device to the work
30-40 dollars per filter
carbon 20 dollars
ion exchange resins- prices vary
silver 30-50 dollars
perfect for families, can be sold to families of 4-5+ and that would let a community of 20-30 people have multiple
costly, doesnt eliminate stronger bacteria
