Abstract:
Due to prevalent flood conditions, Pakistan is facing a severe shortage of clean
drinking water in flood-affected areas. Not only that, but the water quality in the
country is also getting worse day by day. Flood victims are forced to drink
contaminated flood water which has a negative effect on their health due to the
microorganisms and bacteria present in the water; the need to ensure the
availability of clean drinking water is of utmost importance. The report is based on
the design of a portable water purifier containing natural purifying materials to
make it cost efficient and to ensure easy availability of clean water to flood victims.
The results of testing the natural filter media show that active carbon as a filter
media has very high turbidity removal efficiency i.e., up to 98%, and removes
many toxins from water, such as volatile organic compounds and chlorine. It also
adds important minerals such as iron, magnesium, and calcium into the water.
Gravel holds back precipitates that may contain impurities and hold other sandsized
particles. This material not only cleans water chemically and mechanically
but also makes the purifiers cheaper as they are easily available natural materials.
