Summary
Abstract
Milking systems, electrolyzed oxidizing water, CIP, clean in place, ATP bioluminescence Electrolyzed oxidizing (EO) water is a technology that electrolyzes a weak sodium chloride solution into sodium and chlorine, resulting in two solutions alkaline and acid. The goal of this research is to determine if EO water is an acceptable cleaning agent for pipeline milking systems. After constructing 1.5 inch-diameter pipeline milking system, the system was soiled using raw milk that had been spiked with common raw milk microorganisms. After soiling, the system was rinsed with warm water and then evaluated in several locations for initial counts. To evaluate the level of soiling, the surfaces were evaluated using an ATP bioluminescence method. The milk contact surfaces were also swabbed for microbial analysis. The pipeline system was then washed with an alkaline EO water treatment followed by an acidic EO water treatment. After treatment, the effectiveness of the treatment was evaluated by ATP bioluminescence and microbiological analysis. First, a 10 min wash with 60C alkaline water followed by a 10 min wash with 60C acid water successfully removed all detectable bacteria and ATP from the non-porous milk contact surfaces. Shorter treatment times (5 and 7.5 min) with EO water were also tested, along with a control treatment using conventional dairy cleaning chemicals. Using ANOVA, there were no significant differences between the EO water treatments and the conventional treatment, however the 5-min EO water treatment was significantly less effective than the 10-min treatment.

Reading this responsibly
Published figures are obtained under controlled conditions, usually on clean surfaces or in defined matrices. Organic load, surface condition, temperature and application coverage all affect real-world performance. Use these numbers to design a protocol, then validate it on your own site with environmental swabbing.
Applying it
Concentrations in this range are within the adjustable output of every EcoloxTech commercial system, so implementing this protocol is a settings question rather than a procurement one. Where the claim needs to sit on a registered label, see HOCl-AS200, EPA Reg. No. 101112-1.
