Cleaning and Disinfection

Ozone is revolutionising the mains cleaning and mains disinfection industry. With more local government authorities and water utilities reducing their use of harmful super chlorination, Ozone is quickly becoming the preferred alternative across the country.

Grenof use ozonated water for new mains disinfection and have developed a process to use Ozone as an effective way to clean and disinfect new and existing water mains.

Ozone is an incredibly strong oxidant with the added advantage of breaking down rapidly into harmless oxygen, creating an environmentally friendly solution.

Grenof’s proprietary systems create true third-party validation for disinfection. This means customers are assured that true disinfection and cleaning has been successfully achieved. With Grenof's unique mobile ozone trailer design, previously inaccessible areas are now easily accessed giving Grenof the ability to support more customers in more places.

Odour and Corrosion Control

A major contributor to odour and corrosion in industrial systems is hydrogen sulphide (H2S) and its associated compounds. Some industrial wastewater contains sulphur compounds, which provide the molecular basis for the generation of H2S.

Over time this can lead to dangerous leaks, sewer and street collapses. This damage costs the nation billions of dollars in repairs and emergency services.

The good news is that, by updating your hydrogen sulphide treatment regimen, you can address both problems at once, eliminating odours and preventing corrosion. 

Grenof provide two solutions for this:

  • Phodine; and
  • Ozone

Our successful treatment for wastewater odour and corrosion will:

  • End sulphide production
  • Quickly eliminate sulphides present
  • Bring about no additional hazard to life or the environment
  • Not harm the collection system
  • Create no additional downstream challenges
