EFFICIENCY OF IRON REMOVAL FROM DRINKINGWATER WITH HOUSEHOLD FILTERS

The concentration of total iron is one of the main physicochemical indicators of the safety and quality of tap water. The standard amount of the concentration of common iron in tap water is not more than 0.2 mg/dm3. In some cases, due to specific natural conditions and technology for drinking water preparation/treatment, this number may be increased to 1.0 mg/dm3. Excess iron concentration in the water adversely affects the skin, blood composition, etc. Prolonged consumption of water with high iron concentration leads to liver disease, causes allergic reactions, etc.

Comparative Assessment of Corrosion Behaviour of Mild Steels 3, 20 and 08KP in Tap Water

Comparative assessment of corrosion stability of mild steels 3, 20 and 08KP in tap water was conducted. Similar corrosion behavior of these steels was shown by weight loss, linear polarization resistance and polarization curves techniques both for pretreated and corroded surfaces. The discrepancy of the results obtained with the LPR and weight loss techniques was found out and its possible reasons were discussed.
