What is Dissolved Sulfide?

Sulfides come in three categories: organic, inorganic, and phosphine. Organic sulfides are compounds that are formed when sulfur bonds to two organic groups. Inorganic sulfides are compounds that contain a negatively-charged sulfide ion. Phosphine sulfide compounds are formed when sulfur bonds with an organic phosphine.

Sulfides (also spelt Sulphides) can be found naturally in well water and can build up in wastewater collection systems due to anaerobic conditions. In drinking water systems, sulfides cause taste and odour problems and in wastewater systems, sulfides cause damage to concrete structures in collection systems and contribute to odor problems in treatment facilities.  In addition, sulfides are used in mercury removal processes and are frequently found in tanning wastes.

Dissolved Sulfide monitoring

Sulfides give water a bitter taste and the odour of rotten eggs and if left untreated makes it unsuitable as a source of municipal drinking water.  However, with appropriate, reliable and accurate monitoring and treatment, the water can then be made available to the public. 

ATi manufacture a range of accurate and reliable monitoring solutions to assist with the management and control of odour and taste issues, providing advanced instrumentation to help plants and processes operate smoothly and efficiently, with lower operating costs.
