How to reduce manganese level from drinking water?

Published by

Hello everyone!

My company is responsible for managing drinking water quality for 96 water wells in Romania. Some of these wells have high level of manganese (aprox. 100 μg/l), higher than the permissible value.

I need a solution to reduce the level of manganese from these water wells.

Please send me your suggestion for this problem.

Liberty Hydro could likely do this with their advanced filtration system. Here's the website: http://libertyhydro.com/

Managnese is not dangerous for health but must be removed because it gives a dark color and steel smell to the water.

To remove manganese you need to make an oxidation from Mn+2 to Mn+4 and the precipitation will be MnO2 and you can remove this with sand filters.

Oxidation with oxygen some time is not sufficient and you can add chemical reagents like : ClO2, Cl2, KMnO4 or O2.

Dear Madalin

The most common way to remove Iron and manganese from water is by oxidizing the manganous and ferrous ions followed by precipitate removal by settling and filtration. Oxidation could be physically by air induction and / or chemically by permenganate dosing
