Combating Hydrogen sulphide odours
Sep 12 2022
Hydrogen sulphide (Hâ‚‚S), is a toxic gas that is often found in sewerage systems, sewage treatment works and industrial wastewater treatment facilities. It develops due to biological activity in oxygen limited environments within the wastewater.
There are many technologies to combat odour pollution linked to hydrogen sulphide. Some only mask the problem; others, such as YaraNutrioxTM are preventive. YaraNutrioxTM is a natural process developed by Yara since the late 1980s. It is used by municipals at thousands of locations globally with H2S problems.
YaraNutrioxTM acts at the source of the problem, and is often automatically injected at precise amounts by Yara’s advanced dose management technology, where and when needed, into sewerage systems or sewage treatment works. Using complex modelling and dosing equipment Yara ensures the optimum injection rate is applied to eliminate odour complaints from the community and prevent the risk of employee or public exposure to this highly toxic gas.
