More Information
Summary:The invention concerns a method for treating water for human consumption, so as to eliminate manganese and possibly other metals comprising steps which consist in: causing said water to pass at least over a bed of filtering material (3) consisting at least partly of manganese dioxide granules, said granules having a real density ranging between 3.5 and 4.5 and a hardness higher than 6 on the Mosh scale; regenerating, if necessary, said manganese dioxide, said regeneration being carried out mechanically.
