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. .
