� INTRODUCTION TO ECA
• ECA = Electrochemical Activation of water.
• Innovation separates & harvests two distinct component streams
converting Brine into an environmentally friendly disinfectant and
cleaning agent
• Anolyte
• Catholyte
� THE DETERGENT: CATHOLYTE
• Catholyte:
– Carries a negative charge
– Reducing solution (excess of electrons)
– Potent anti-oxidant (ORP> -900mV)
– Ph. 9 to 12
– Sodium Hydroxide (NaOH), Hydroxide (OH-), Hydrogen (H2), Hydroxyl (HO2-)
� THE DISINFECTANT : ANOLYTE
• Anolyte:
– Carries a positive charge
– Oxidizing solution (ORP < +1000mV)
– Range of natural mixed oxidant radicals
– pH range 2.0 to 9.0 - different radical species
– Microbiocidal – disinfectant/sterilant
– Eliminates microbes “electrically”
– No resistance capacity
– Diverse range of disinfecting applications
– Hypochlorous Acid (HOCl), Chlorine Dioxide (ClO2), Ozone (O3),Hydrogen
Peroxide (H2O2), Hypochlorite (OCl)
� HOW IT WORKS?
• The Anolyte water molecule (high +ve ORP) scavenges the electrons from the microbe surface.
• Alters the cell wall structure (proteins)
• Ineffective cell regulation
• Resulting in cell death through leakage and eventual lysis.
• Dual mechanism – also chemical (HOCl)
� ECA MICROBIAL EFFICACY
• Anolyte has a 100% kill rate on Gram Positive and
Gram Negative Bacterial Strains, Viruses,Fungi,Yeast
and Mould including
• Salmonella, Legionella, Listeria,E.Coli 157:H7
• Polio,Hepatitus A, Candida Albicans
� BIOFILM ASSOCIATED PROBLEMS
• Increased downtime to clean
• Increased use of chemicals during cleaning
• MIC (Microbial Induced Corrosion)
• Scale buildup
• Often in inaccessible places
• Constant recontamination
� BIOFILM CONTROL WITH ECA
• Initial clean with Catholyte
– Strip existing biofilm effectively
• Sterilization of piping with Anolyte
– Ongoing control of biofilm due to addition of Anolyte
– Constant reduction of micro-organisms
• Affects ability of organisms to adhere due to
electrostatic interactions
• MINIMISED BIOFILM FORMATION & REDUCED
DOWNTIME
ADVANTAGES OVER CHEMICALS
• CIP times may be reduced by up to 70% due to shorter contact time that is required relevant to chemicals.
• ECA is applied at ambient temperatures providing substantial energy savings
• Water savings may be achieved due to shorter cleaning and disinfection cycles as well as the ability to reclaim for subsequent re-use
• Substitution of ECA with Conventional chemicals can result in significant cost savings.
ADVANTAGES
• On-site production removes the need for
transportation and storage of chemicals
• Reduced chemical handling by staff results in
increased labour efficiency
• Effective at removing and controlling Biofilm
• ECA is approved for use on food contact surfaces
• ECA is safe to handle and be in contact with food and
beverage products.

LEARNING'S
• Not all plants are the same. We have developed pre-application assessments to determine viability. – Water pH can affect ECA efficacy
– Hygienic design would affect cleaning & microbial efficacy
– CIP optimisation (Manual vs. Auto operations/integrations)
• If ECA application recommendations are not followed ECA can be corrosive.
• Buy in from plant is essential (champion)
• Training learning's• Dedicated training department that deals with pre/post training and follow up.
• After Sales service
• On going technical interaction with RW technical team.
� LEARNING’S ON CORROSION
A study was conducted to simulate the effect of Anolyte at
application strength flowing through SS304 and SS316 for a
12 year period (making the assumption that 2 CIPs were
performed each day)
– Results of study
• No negative effect on good quality SS304 and SS316
• Poor quality welds had negative effects from continuous extended
contact
� CORROSION CONSIDERATIONS
• General Recommendations
• All concentrate solutions to be stored and transferred in PVC
• Audit (SWEEP) conducted on filling machines before introduction
• Welds correctly pickled & passivated
• Equipment passivated on annual basis
• Welds to be hygienic welds appropriate for food processing facilities
• Weak points in equipment identified and monitored
• All dead spaces, dead ends and similar minimal flow areas to be
addressed.
• SS equipment, specifically where stagnant solutions are present must be
monitored annually
� LOW CHLORIDE GENERATOR
• Radical Waters new Low chloride generator (LCG)
– RW new generation of Devices were recently introduced
into the market with the aim to substantially reduce
corrosion concerns related to the use of Radical Waters
ECA solutions.
– Residual chloride levels are within the recommended OEM
specs.
– Smaller dilutions can be made. 10% instead of 20%
