How To Handle Sulfur Smell, Bacteria, and Hardness in Well Water

 have sulfur smell in my well water. I am needing a system to remove smell and filter out coliform bacteria and remove hardness. results from lab test: sulfur total by ICP - 60.6mg/l hardness   grains/gallon.  Total dissolved solids - 757 mg/l.  My ph 7.7. However, iron and manganese are low and not a problem. What do you suggest?

To thoroughly treat this water, we can recommend using a Precision-24 chlorine injection metering pump, which provides extra strength oxidation for killing bacteria and oxidizing high levels of iron and manganese (which can be linked with sulfur odors).  

Following the point of injection, the chlorine would then feed into a 40-gallon contact tank to provide enough contact time for the solution to react with the sulfur and especially the coliform or e coli bacteria in the water.  After the contact tank a backwashing carbon filter would remove any trace of chlorine smell and taste and filter the water of sediment.

Finally, you could use an efficient salt-based water softener to eliminate any hardness present in the water. The result would be clean, fresh, soft water throughout the home.

Check out the diagram below and see how it works:
