How do I get rid of mercaptan?
Oxidation is the only method that completely eliminates mercaptan odors. Precipitation technology may adsorb some mercaptans, but may readily release the adsorbed molecules. Removal of sulfide by precipitation often allows the odor from mercaptans to be more apparent and equally offensive.
What smells like gas but is not gas?
Sulfur is often the cause of a gas smell in homes without gas leaks. It smells identical to the foul rotten odor of gas leaks, but it's not nearly as harmful in this case.
