Abstract
This relates to a process and corresponding plant intended for the treatment of water after iron and manganese in solution have been removed, which is characterized mainly by the fact that regeneration of the manganese dioxide takes place concurrently within tank A containing a filter bed B of monocrystalline quartz granulate or other equivalent material, or with descending flow or in any event in the same direction as the water being treated, while both physical removal of the sesquioxide and its delivery to the upper part of filter B and cleaning backwashing is performed countercurrently. <IMAGE>
