INTRODUCTION

Most natural waters contain some iron. The concentration may vary from small traces to
very large amounts in water which is contaminated by acid mine wastes. For domestic
use, the concentration should not exceed 0.2 ppm and for some industrial applications
not even a trace of iron can be tolerated. There are many means available for removing
or reducing the iron content. Water softening resins are effective for removing small
amounts of iron and special ion exchange materials are selective for iron removal. High
concentrations of iron can be removed by such chemical processes as oxidation and lime
or lime-soda softening. Because of the many means of removing or reducing the amount
of iron in water, the particular method employed will depend largely on the form of iron
which is present and the end use of the treated water.
