UNIVERSITY OF
ALBERTA STUDENTS INTRODUCE A LOW TECH WATER FILTERING PROCESS, by KATHY

UNITED

May 2008 -- It
is a tale centered on the introduction affordable sustainable technologies.
A
group of students from the University of Alberta (Canada) are coordinating a
Kenya Ceramic project that is focused on delivering a low tech water filtering
process to villagers living in rural communities.
The
Kenya Ceramic Project (KCP) is a pilot program aimed at introducing innovative
ceramic water filters and high efficiency wood burning stoves to rural areas in
Kenya.
With
the help of NGO’s and health clinics, potters in these areas are being trained
to make specially designed filters and stoves with two goals in mind: increasing
access to clean water and introducing a more efficient use of available fuels.
Essentially
simple clay pots are being introduced to serve as a low-tech, low-cost water
filter and as part of an efficient heating/cooking unit.
The
pots are inexpensive and made by drying clay and mixing it with sawdust and
different types of grass.
When
the pots are fired in an energy-efficient designed kiln, the organic material is
burnt away – leaving small holes that can filter out bacteria.
The
challenge with this technique – making sure that the pots are used properly
and ensuring that the clay mixture doesn’t filter the water too quickly.
The
pots designed by the students from the University of Alberta filter water at a
rate of approximately one liter per hour.
Testing
of these pots has demonstrated a 100% elimination of coliform bacteria from the
drinking water supply.
And
the ceramic pots can also maximize target heating as part of the cooking process
– thus reducing the amount of fuel needed to heat water or other cooking
materials.
During
the upcoming summer 2008, the U of A students will return to Kenya to continue
working with a village where a pilot project is in the works that involves the
construction of a small pottery factory and test a design for a high-efficiency
cooking stove made of clay pots.
UNICEF
has expressed interest in facilitating the expansion and proliferation of the
KCP water filter program.
