A filtering container has an upper zone fitted with means for bringing the water admitted into contact with a large vol. of oxygen, so that the iron in soln. can be removed. A storage container connected to the filtration container, has a level detector which controls the feed pump delivery of raw water into the filtration container. Beneath the two containers there is a lead with a valve. This is extended from the filtering container and is connected to the delivery of a pump, the suction side of which joins the storage container. A second valve is fitted in this extended lead. A mass of filtration material is provided in the first container and a drain is protected by a gauze. The inlet chamber has the form of a closed funnel and the delivery pipe has a number of aerating holes for the water which is to be rid of its iron. Under the inlet a baffle plate is fitted and below this there is a connection from a fan blowing in oxygen. To remove the iron from water and esp. from well water in which it is present in large amts., so that it does not block the pipes and cause brown stains in the toilets, etc. The arrangement works efficiently and with maximal security.
