Hello Madalin.
In Brazil we use to use ZEOLITE as a quick and cheap treatment for Mn and Iron removal, on low/medium concentrations.
Some free information about it you may find on wiki: https://en.wikipedia.org/wiki/Zeolite
Find some good local Zeolite provider on you region and talk to him. He'll help you on the design of a good solution, based on the parameter of flux, Mn concentration in and out, etc. (like the other fellows here already told you).
Cya!

Purojal DW-7% Conc. Oxy Chlor oxidizing biocide will remove manganese from drinking water. If you require more information please send me an email at advenvtech@gmail.com so that I can share more information with you.

A concise summary of the treatment options can be found at http://www.watertechonline.com/an-in-depth-look-into-iron-and-manganese-treatment.
The situation is usually complicated with presence of high levels of iron which is often the case for borehole sources drawing from greensand aquifers.
Presuming you are treating to EU drinking water standards (50ug/l) there are many case studies to draw from. One, treating high levels of Mn and Fe in greensand water can be found at http://www.barhale.co.uk/downloads/Water%20Roydon.pdf?PHPSESSID=0af5ddd4644a5ccd33fab251ab3a2cb8
A major problem caused by Mn in the supply is the deposition of MnO2 in the mains causing turbidity problems and customer complaints. Thus, this project was linked to an associated mains cleaning programme. http://dwi.defra.gov.uk/stakeholders/improvement-programmes/afw/afw3472.pdf

Some of the methods discussed in the comments are best if you are planning centralized treatment of the water source. Other methods might be better if the treatment is decentralized or at the point of use. It would be good idea to share flow rates, concentration of Mn and your thoughts on treatment strategy.

As you can see from the other comments there are various methods to attain manganese removal, each of which is valid under set conditions. However, when posting a question you should provide more detailed information, i.e., flow rate, concentration of Mn, local regulatory limits for Mn in drinking water, as the proper method for treatment will depend on these parameters.

Assuming the location is Romania, the likely limits will be the EU standard of 50 ug/l.

The current most common removal method is oxidation-precipitation-filtration. It is popular because it is inexpensive to implement, easy to operate and takes very little physical space. Some do elect to use biological removal although there really is no advantage over the above unless there are secondary contaminants to be removed. If all you want to remove is Mn then you can: A) feed KMn04 or NaMn04 to aid in oxidation and precipitation of the Mn and after a few minutes of contact the Mn can be filtered out or B) you can use an Mn02 coated media to aid in precipitation such as pyrolusite, greensand etc. For higher flow rate installations we coat ceramics with Mn02 on site to make high rate Mn removal contractors. Be clear if you have other contaminants like turbidity or Fe to remove as this impacts the chosen removal technology.

I can Suggest Bioremediation.My bacillus is a sturdy bacteria that can take away a lot many heavy metals and at no extra costs you can reuse the manganese into something that can give you some money as well.
