Abstract

PURPOSE: To provide an iron-removing filter material in a process of forming film of γ-oxyhydroxide of iron on filter base material such as sand by a method wherein a calcium based hardner such as cement is used as a fixing material so that oxyhydroxide of iron is fixed cheaply and securely.
CONSTITUTION: The filter base material such as sand or zeolite is charged in a rotary reaction kiln, next sodium hydroxide and a ferrous salt such as ferrous sulfate are charged and mixed, then a calcium based fixing agent such as cement, slaked lime or the like is charged, so that γ-oxyhydroxide of iron film is fixed on the surface of the filter material by the action of reaction heat and CO2 gas in the air. In this manner, film of γ-oxyhydroxide of iron is cheaply and securely fixed, thereby providing an iron-removing filter material used in an air oxydation process.
