Processes for oxidation and removal of iron and manganese in drinking water treatment plants (WTPs) – examples of WTP Velekince in Gjilan and WTP Badovc in Prishtina
Session
Agriculture, Food Science and Technology
Description
This study analysis options for oxidation and removal of iron and manganese in the drinking water treatment industry and presents two cases – the WTP Velekince in Gjilan and the WTP Badovc in Prishtina. Iron and manganese are usual constituents in the ground and surface waters. Although not harmful for human health at low concentration, manganese compounds can cause aesthetic problems, such as staining of fixtures & laundry and taste problem. High concentrations of manganese and long-term exposure can have adverse impacts on the human health, particularly affecting the nervous system. In the water treatment industry, the main concepts used to remove these two elements, to comply with the applicable drinking water standards, is based on the redox reactions; which converts soluble forms of iron Fe2+ and manganese Mn2+ into insoluble compounds, which are removed through subsequent gravitational settling and filtration processes. The most common oxidizing agents used in water industry to remove iron and manganese are: oxygen from the air, chlorine, potassium permanganate, chlorine dioxide, hydrogen peroxide and ozone.
Keywords:
