A process and apparatus for the treatment of water, especially iron and manganese containing phreatic water, wherein water is flowed through a substantially coarse-grained filter or under and/or over flow barriers in a low filter vessel (1, 10, 13, 15) having a small, e.g. 5:1 cross-sectional surface area relative to that of the body of water. The water to be treated is set to flow in horizontal direction along a coarse-grained (o &cir& / >= 1mm) filter stuff or flow barrier located on the interface of air and water. |
