Septicity Control

Sewers can often suffer from a lack of air supply, stagnant areas and warm temperatures which can all lead to undesirable biological results.

Under these conditions bacterial activity in sewage rapidly consumes the small amount of dissolved oxygen that may be present, resulting in the proliferation of fermentative bacteria. 

The sewer then becomes a biological reactor, producing hydrogen sulphide that is held in the sewage until the point of release to the atmosphere.


Hydrogen sulphide gas can cause severe acid corrosion, rapidly corroding concrete and in some cases reducing asset life to less than five years. It can also lead to odour complaints due to its’ bad egg smell.

Anomex has been developed to prevent this hydrogen sulphide build-up and is available in both sodium nitrate and calcium nitrate forms. Both products are proven to be extremely cost effective septicity control agents tested, used and approved by UK water companies.
