More analysis
I second Ralf's comments. A more detailed analysis of what else is in the water is needed. Aeration is usually the first and simplest option to consider, but, the presence of significant levels of iron, manganese, organic carbon, etc may require additional or alternative treatment solution(s) to be adopted. There are plenty of comments about alternative processes that have their place (ie application), but, you want to be sure that you really need to use them as they all involve additional complexity and cost (both in terms of capital as well as operating and maintenance).
