DESCRIPTION:Speakers: Joseph A Varkey (University of Swaziland)\nThe suppl
 y of adequate clean water to communities is a problem in many countries\, 
 especially in Africa where the rural population depend on water from river
 s\, dams and streams for domestic use. Such water contains many chemical s
 ubstances and microorganisms that affect the health of human beings and an
 imals. Use of simple water purification systems\, like filters\, by househ
 olds\, is a possible solution to this problem.  In our laboratory\, we hav
 e developed a porous pot water filter using sawdust and clay.  Both materi
 als are available locally. Sawdust was sieved using 100\, 250 and 600 micr
 ometer sieve and then mixed with clay in the clay/ sawdust ratio of 1:3 by
  volume. The mixture was then used to make pots\, which were porous. These
  pots were tested for their capacity to purify contaminated water collecte
 d from rivers. The filtration rate\, as a function of the clay/coal ratio\
 , was also measured. Subsequently\, quality tests were done on the filtere
 d water and raw water to determine the potability of the filtered water. T
 he tests included microbiological\, physical and chemical properties. The 
 results were then compared with standards provided by World Health Organiz
 ation.\n\nhttps://events.saip.org.za/event/7/contributions/4980/
