Abstract: (10747 Views)
There is a need for simple and inexpensive water supply systems in small communities, mainly because of high costs and water resource shortages. Ceramic filters used as a Point-of-Use (POU) system could serve as a safe and inexpensive means for supplying water. In this research we looked at the possibility of using Iranian traditional ceramics as filters for drinking water, bearing in mind the importance of ceramic filters as a POU system. A number of parameters relating to water quality were measured before and after filtration through a ceramic pipe wall. We used ceramic pipes made of clay (with 90% purity). It turned out that ceramic filters are capable of eliminating indicator microorganisms and turbidity to a considerable degree. They can also remove 70% of the water's color. But this system could not eliminate Dissolved Solids, Electrical Conductivity, Hardness and the Nitrate ion content of water. Using Mann-Withney U Test and T- Test, it is confirmed that increasing the thickness and number of ceramic pipes is not effective for improving some water parameters. This research showed ceramic filters can be useful for household water treatment in places where there is microbial pollution or high turbidity.
