Changes in the Iron and Manganese Content and Turbidity in the Vilnius City Water Supply System Gele ies, mangano ir drumstumo kitimas Vilniaus miesto vandentiekyje

The water of Vilnius boreholes contains excessive quantities of natural iron and manganese, the insoluble forms of which increase the turbidity of the water. Therefore, a ISC Vilniaus Vandenys installed water treatment equipment that remove iron and manganese from drinking water, and decrease the turbidity of the water. Water samples were taken at different points of the water supply network, total iron, manganese content, and turbidity analyses were carried out, and the changes in indicators mentioned above were observed in the water supply network. It was established that this indicators concentrations are changing at water supply networks, but do not exceed the norms allowed by HN 24:2003.
