METHOD FOR REMOVING IRON IN BOILER BLOW WATER

摘要

PURPOSE:To provide an inexpensive and easily driven method for removing iron from a boiler blow water and recovering regenerated water. CONSTITUTION:In a method for removing iron from a boiler blow water contg. iron hydroxide and iron ion, the boiler blow water is exposed to an oxygen- contg. gas by using an active carbon as an oxidation catalyst and iron hydroxide and iron ion are oxidized to make an easily separable iron by using a membrane and then, produced insoluble iron is separated by means of a membrane.
