Location: Nigeria

Oil Production: Economic Backbone
 9th largest in the world
 80% of foreign exchange earnings


One of the fastest growing economies
Urban and Rural Nigeria
Filtration

Goal: Remove all harmful materials from water
Top priority: Kill all bacteria that causes disease.


Many rivers in Nigeria

Major Rivers: Niger and
Benue
35% of people have
access to clean water
Community ownership
and operation of rural
water sources.
Many filters are not
operational.

According to several reports, some form of
Ceramic Filtration with activated carbon has been
proven the most cost-efficient and effective way of
purifying the waters of Africa.
100% of the water that was filtrated with the
Ceramic Filter was free of bacteria, while water
that was not filtered was only 15.5% free from
bacteria.
In a report by UMI, they claim that water
treatment by Ceramic Filtration reduces diarrhea
by its consumers by 30-40%. Diarrhea is a major
cause of death in developing countries because it
causes the person to become dehydrated

Types of Possible Filtrations

Coal Filter, Paper Filter, Micro Screen Filter, Iodine,
Ultraviolent Light, Boiling Water, Portability


Scale: 1 is the lowest…4 is the highest
Compared 4 different filters

Carbon/Charcoal Filter, Brita Water Filter, UV
radiation, Ceramic Filter


AHP made through research
Three main categories
People & Use: How many people can use it and how
simple is it to operate?
 Purification: How well does it clean out harmful
materials in the water?
 Production: How easy is it made, fixed, and
maintained?



Most important feature is purification of water
Make filter with material naturally available to
Nigeria
