Odour & Septicity Control – Wastewater | Acorn Water

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,.
