Since the filter basins are engineering works, they are subject to an
Due to the natural conditions, there are various water extraction methods (reservoirs, deep wells, slow filter). Especially in urban areas, drinking water is of great importance by slow sand filters. Since this filter basins are mostly a multilayer structure and are exposed to high stress, regular maintenance is necessary.
When filtering the water fines are shifted to the lower gravel body, this
Central activities in the management of slow sand filter is the
