Which oxidant used for iron and manganese will react with hydrogen sulfide and will not form trihalomethanes?

Potassium permanganate is a strong, practical oxidant for iron and manganese that also reacts readily with hydrogen sulfide. It converts H2S into sulfur or sulfate, helping remove odors, while oxidizing Fe2+ and Mn2+ to form insoluble oxides that can be filtered out. Crucially, permanganate is not a chlorine-based disinfectant, so it does not create trihalomethanes, which are formed when chlorine reacts with natural organic matter during disinfection. Other oxidants may oxidize Fe/Mn and sulfide to some extent, but chlorine-based chemistry carries the risk of THM formation, making permanganate the best fit for all these requirements.
