Oxi-Tech’s Pulse Oxidation (POd) introduces new approach to dairy hygiene

Ground-breaking study results demonstrate unmatched efficacy against mastitis causing pathogens

All dairy producers have access to a new cost saving, chemical-free and safer approach to controlling mastitis causing bacteria and subsequently enhancing their milk quality management following independent microbiological studies.

“Oxi-Tech’s Pulse Oxidation (POd) technology which uses just cold water and low voltage electricity to create ozone – a clean and powerful disinfectant killing bacteria, viruses and fungi, has been proven to achieve within seconds over 99% reduction in E. coli, Staph aureus, and Strep uberis, according to the latest study findings,” reports Oxi-Tech’s Luke Rutterford.

“Designed for seamless integration into existing dairy operations, both conventional and automated, POd now has the proven ability to provide consistent pathogen control across mains and borehole sourced water and can subsequently be introduced to two key stages in all producers’ milking routines. Firstly, during teat preparation the system can eliminate the requirement for a pre-milking teat cleaner (PreMTD), while post milking, POd has also been proven to successfully replace the traditional CIP wash.

“Producers with automatic cluster wash systems can introduce POd and subsequently eliminate chemical usage. Finally, they can introduce POd to their water supply systems ensuring pathogen-free drinking water to reduce bacterial load in the herd.”

He continues: “The technology also brings improvements to operator safety by eliminating the handling of harmful chemicals. In addition, the reduced transportation, use and disposal of the chemical’s plastic containers will also significantly lower a dairy unit’s Carbon footprint and contribute to its net zero targets.”

The results follow on from a DEFRA funded Innovate UK R&D research project at Agri-Tech’s South West Dairy Development Centre which concluded that POd retrofitted to the unit’s automated milking system demonstrated it was a cost-effective CIP method, cutting energy costs by 24% and proving to be 50 times more efficient in energy usage compared to existing treatments.

Luke Rutterford adds: “The study findings reaffirm Oxi-Tech’s POd technology and the company’s commitment to offering a ground-breaking alternative by providing dairy farmers with a chemical-free, low-energy solution to maintain hygienic water and milking environments. By preventing infections at the source, Oxi-Tech’s system supports efforts to reduce antibiotic usage, aligning with global initiatives to combat antimicrobial resistance.

“Our technology not only improves outcomes for farmers providing them with a powerful solution towards protecting their herds and enhancing milk quality, but also contributes to a healthier, more sustainable future for the dairy industry.”

Oxi-Tech’s Pulse Oxidation™ Technology Proves Superior in Food & Beverage Industry Testing

Oxi-Tech have achieved groundbreaking results in a recent industry trial, demonstrating the superior efficacy of their Pulse Oxidation™ technology in the Food & Beverage sector. Conducted at Devon Drinks in Dunkeswell, the trial validated Pulse Oxidation™ as a powerful chemical-free solution for Clean-in-Place (CIP) processes.

The trial involved a direct comparison between three different cleaning methods—traditional chemical-based cleaning, water-only rinsing, and Oxi-Tech’s Pulse Oxidation™ process. The study aimed to assess each method’s effectiveness in reducing microbial contamination within Pressure Vessel Tanks (PVTs) used in cider production.

Key Findings:

  • Unmatched Cleaning & Disinfection: Pulse Oxidation™ outperformed chemical-based cleaning, achieving up to 95% greater efficacy in disinfecting the entire system.

  • Superior Microbial Reduction: Test results showed significantly lower Total Plate Count (TPC) and ATP readings after Pulse Oxidation™ treatment compared to both chemical and water-only methods.

  • Sustainable & Chemical-Free: By harnessing low-voltage electricity and water, Pulse Oxidation™ eliminates the need for toxic chemicals, providing a more environmentally friendly and cost-effective CIP alternative.

“This trial further reinforces the power of Pulse Oxidation™ as a revolution in industrial water treatment,” said Luke Rutterford, Project Director at Oxi-Tech. “The results demonstrate not only its superior cleaning performance but also its potential to enhance operational sustainability within the Food & Beverage industry.”

Transforming Industry Standards

The trial also validated Pulse Oxidations efficacy throughout the entire CIP pathway, including tanks, carbonators, and canning equipment. Even after a reduced CIP cycle time, Pulse Oxidation™ maintained high levels of cleaning effectiveness, showcasing its efficiency in large-scale industrial applications.

In conclusion, the Chemicals and Pulse Oxidation were significantly more effective than Water in terms of Cleaning and Disinfection, thereby reducing subsequent residual microbial growth. Pulse Oxidation was more effective at Disinfecting the system than the Chemical treatment. In this small-scale trial, Pulse Oxidation proved to be up to 95% more effective then Chemical treatment at disinfecting the system as a whole.
With a growing focus on sustainability and reducing chemical footprints, Pulse Oxidation™ technology is poised to revolutionise sanitation processes across multiple industries.

Chemical free cleaning and disinfection for robotic milking systems

Pulse Oxidation Dairy (POd) reduces energy costs by 24% and outperforms conventional disinfection systems: Innovate UK DEFRA study findings at South West Dairy Development Centre.

Introducing Oxi-Tech’s Pulse Oxidation (POd) to robotic milking systems has cut energy costs by 24% and proved to be 50 times more efficient in energy usage compared to existing treatments for automated milking systems, according to results from a DEFRA funded Innovate UK R&D project.

POd which uses just cold water and low voltage electricity to create ozone, a clean and powerful disinfectant killing bacteria, viruses and fungi, was retro-fitted to the robotic milking systems at Agri-Tech’s South West Dairy Development Centre.

The Centre’s three robotic systems were alternatively fitted with POd and conventional treatment and monitored to analyse the comparative performance of each.

Oxi-Tech’s CEO Paul Morris comments: “We were delighted with the findings of this six-month trial. The research team concluded that POd not only proved to be a cost saving, highly efficient disinfectant but also brought improvements to operator safety by eliminating the handling of harmful chemicals. The reduction in the use and disposal of plastic containers will also significantly lower a dairy unit’s Carbon footprint and contribute to its net zero target.”
