Hydroxon™ AOP (Advanced Oxidation Process) – disinfection innovation for water recycling and reuse

December 2019

An independent validation report has confirmed the outstanding disinfection performance of HydroxonTM on municipal wastewater to produce recycled water

A quarter of humanity is facing looming water crises driven by climate change, increasing pollution and population growth. 17 countries around the world are currently under extremely high water stress, meaning they are using almost all the water they have, according to recent World Resources Institute data.

The recycling of municipal secondary effluent into both indirect and direct potable water reuse have emerged as promising options to tackle these challenges and provide alternative water resources.

Infinite Water is pleased to announce independent third party validation of the  Hydroxon™ process for the treatment of secondary effluent from municipal wastewater treatment plants.

The objective of the validation study was to determine the reduction in microorganisms across the Hydroxon™ treatment process when treating municipal secondary treated wastewater to produce recycled water. The validation study assessed disinfection performance for three broad groups of microorganisms (protozoa, viruses and bacteria).

The results confirm that the Hydroxon™ process is capable of producing fit-for-purpose Qld Class A+ and Australian Guidelines for Water Recycling (AGWR) dual reticulation recycled water from secondary treated municipal wastewater effluent.

Conventional water treatment systems typically rely on Ultraviolet (UV) light, ozone injection or membrane filtration (energy intensive and costly), or on the use of chlorine to meet required disinfection performance. Infinite Water's Hydroxon™ process does not require any of these to achieve ADWG disinfection guidelines. In applications where multiple disinfection barriers are required, the HydroxonTM process can effectively be integrated with conventional processes like Ultrafiltration and chlorination.

In addition to disinfection, Hydroxon™ solutions also achieves improvements in the overall physical characteristics of the water such as odour, taste, colour and turbidity as well as chemical properties of the treated effluent through reduction in nutrients, metals, organics and emerging unregulated contaminants.

The validation testing results have put a spotlight on the Hydroxon™ process as a strong contender for disinfection and confirmed it as an effective option to supply high quality recycled water for unrestricted reuse applications as well as for indirect and direct potable reuse.

The integrated design, small footprint, high recovery and considerably lower operating costs of the Hydroxon™ process are key advantages in comparison to competing technologies for treating secondary effluent of municipal wastewater.

Dr Dan Deere (Water Futures), recognised as a highly reputable water sector expert, supervised the testing methodology, witnessed the challenge testing and wrote the validation report. Prof. William Clarke (from the University of Queensland) reviewed the report.

Independent testing analysis was undertaken by the respected Australian Water Quality Centre laboratories in South Australia. AWQC operate National Association of Testing Authorities (NATA) accredited laboratories.
