What level of sulfur content in ammonia-vaporized wastewater is considered excessive, measured in milligrams per liter?
If ammonia-vapored wastewater is sent to a sewage treatment plant, it depends on the plant’s capacity to handle such waste. For activated sludge, sulfide levels need to be kept below 25 mg/L; otherwise, they can act as toxins to the activated sludge.
The emission standard for sulfides in the \"Emission Standards for Pollutants from Urban Sewage Treatment Plants\" is 1.0 mg/l.
