Wastewater Treatment

Wastewater Treatment: Improve compliance and minimise pollution by sanitising with ClO₂.

ClO2 offers a low cost, highly effective alternative to UV and Peroxide treatments.

Tighter regulation and environmental awareness mean operators are seeking alternatives to chlorination of treated wastewater.

Whilst chlorination using gaseous chlorine and hypochlorite has been the default option for wastewater disinfection for many decades, the increasing complexities associated with regulatory compliance mean that most operators are now actively seeking environmentally friendly alternatives.

Chlorine dioxide treatment of wastewater offers a safe, environmentally friendly alternative that is ideally suited for wastewater applications. The unique properties of ClO2 mean that it does not produce toxic chlorinated by-products as a result of the disinfection, and its selective action ensures that it does not react with inert compounds in the same way as peroxides and ozone, thereby drastically reducing the dose rates needed.


ClO2 is able to cope with turbid waters, and requires low maintenance – making it an ideal alternative to UV systems. Unlike UV, ClO2 will also remove both H2S odours and the sulphide reducing bacteria that cause odour complaints and corrosion.

ClO2 degrades to harmless salt in waste water networks, making it an ideal environmentally friendly alternative.

ChloroKlean manufacture robust and reliable ClO2 disinfection systems ideally suited for wastewater treatment and odour control applications. Full on-board data logging and control is available for environmental audit purposes.

Quick Fact: ClO2 treated systems typically do not require dechlorination prior to discharge.
