Nitrate can be removed by using special ION-EXCHABNGE RESINS which exchange NO3- with Na+. The resins , upon saturation can regenerated with saturated NaCl solution. 

Fe and Mn are removed by oxidation using a catalyst called BIRM which accelerates the reaction.

The reaction produces their oxides which can be retained by using a SAND-FILTER.

Prior to oxidation the water must be fed with excess air using a small air compressor.
