Without suitable treatment, sewage and wastewater can damage the environment and create public health problems. One of the problems associated with this is odour complaints which are caused when bacteria in the wastewater utilise all the available oxygen and reduce any sulphates present to sulphides.

This lack of air supply, stagnant areas and warm temperatures all promote undesirable biological activity, which results in severe acid corrosion and septicity causing severe damage to sewers.

Anomex prevents sulphide gas build up, metal corrosion of tanks and pipes and prevents unpleasant odours.

Anomex 76

A calcium nitrate solution also used to prevent odour and septicity issues but a slightly stronger concentrated solution, meaning dosing is not as frequent.

Application Equipment

In addition, OMEX can supply and install a wide range of dosing systems to ensure regular and consistent dosing of Anomex is achieved. Standard units of 2500 Litre, 6000 Litres and further sizes including 10,000 Litre can be supplied to include onsite commissioning, site installation and tank fill.
