Need economical solutions for iron removal directly from borewell water in Bhubaneshwar, Orissa

The water we are getting from our borewell is yellow in colour. It stains all types of containers. Analysis revealed that it is contaminated with iron & sulphur. Presently we are using a RO filter for drinking water and a small iron fliter (2 candle wall mounted unit) for washing purposes. Could any one suggest a system that can be hooked up directly to the borewell? The filtered water can be pumped to the overhead tank (1000 ltr). Is there an economical technically feasible method of implementing this. I am located in Bhubaneshwar.
