� THE TECHNOLOGY

� 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

� ECA: THE TECHNOLOGY

Anolyte (+ve)

Brine In

Catholyte (-ve)

� 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

FEATURES & BENEFITS OF RADICAL

WATERS ECA

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%
