Cobra ANL is a liquid blend of carefully selected autotrophic microorganisms designed to convert sulphides into elemental sulphur. When applied to sewage networks, it effectively removes dissolved sulphides from wastewater, assisting to reduce odours, and improve overall treatment performance.

The formulation contains specialised bacteria, that target the primary cause of septic odour:

• Volatile Fatty Acid (VFA) – degrading bacteria use VFAs as a food source, converts to new biomass and carbon dioxide (CO2), reducing septic odours

• Sulphide-oxidising bacteria convert hydrogen sulphide (H2S) – the source of the characteristic “rotten egg” smell – into stable, non-odorous elemental sulphur

Autotrophic bacteria utilise inorganic carbon and sulphides to grow and reproduce, continuously generating new biomass while maintaining effective sulphide control.
