Full instruction on the label.


The problem:

In septic tank systems bacteria requires oxygen for breaking down of the organic material. Bacteria preferably consume oxygen that is readily available: elemental oxygen. Once elemental oxygen is used up, sulphate oxygen is next source of oxygen. Reaction with sulphate oxygen leaves the bi-sulphide ions free to react with hydrogen and produce sulphate gases including hydrogen sulphide. These gases are the main cause of septic tank smell.

The solution:

Hydra HS Neutraliser includes oxygen releasing agents which act as a primary source of oxygen for bacteria to use and hence break the sulphide production chain.

In addition, Hydra HS Neutraliser promotes natural bacteria that consumes dissolves hydrogen sulphide and reduce B.O.D. By removing the very source of bad odour (i.e. the sulphate gases), Hydra HS Neutraliser helps in bad odour removal.
