Odour Abatement

Odours and septicity in wastewater generally occur when sulphur-reducing bacteria are deprived of oxygen in anaerobic conditions and carry out respiration using sulphate ions. As a by-product of respiration, the bacteria release hydrogen sulphide gas that smells of rotten eggs. This is a major concern in wastewater treatment because high odour levels may negatively impact local businesses, neighbouring communities, and treatment plant employees. Hydrogen sulphide then converts to dilute sulphuric acid leading to lower pH levels in pipe networks which can result in extremely expensive damage to pipelines. The best way to deal with odour and septicity in wastewater is through prevention.

We offer products that provide bacteria with nitrate ions so that hydrogen sulphide is no longer the final product of microbial respiration. This reduces the amount of hydrogen sulphide produced and therefore regulates the odours and septicity of wastewater.
