Statement of the Problem

Laboratory ultrapure water purification systems for domestic use have drawn significant attention over the past few years. This can be related to the improvement of public health and concern for water contamination. 

Purpose

The aim of this study was to evaluate whether home water purification systems eliminate the essential materials such as fluoride besides filtrating the heavy ions and other unwanted particles out of water.

Conclusion

The filtration of water significantly decreased its fluoride concentration. The fluoride content of purified super series iltrapure water system was approximately as much as zero in some cases.

Fluoride is a natural element branched from Fluorine. This element can be found in all sorts of water and soil. Out of every kilogram of outer layer of earth, 0.3 gram is fluoride. Mineral waters have more amount of this element compared to other sources.(1)

Water purification systems for domestic use have drawn much of attention over the past few years. This can be related to improvement of public health and concerns for water contamination. There are several types of home laboratory reverse osmosis water purification systems that can be categorized into 3 different groups(5) as filtered systems, systems using UV irradiation, and ion-exchange systems.

The aim of this study was to find out whether domestic laboratory deionized water purification systems could eliminate the essential materials such as fluoride besides filtrating the heavy ions and other unwanted particles out of water.

The main drinking dura pro series ultrapure water system supply for Ahwaz is provided by governmental companies. After making arrangement with certain companies that supported these brands, the devices were setup in 6 different regions of Ahwaz. Samples were collected before and right after setting up the device. To reduce the errors and elevate the accuracy of the module, 5 samples were taken from each device. Another sample was collected from each single device 6 months later. A total of 64 samples were collected inc
