Where can we get 5 gallons of this stuff to do a test spot? This is all hype until we see a real world test.

On another note, it sounds like something I once heard about from someone who drank the water and was cured of lyme disease. I think her machine was small enough to fit on a kitchen countertop.

I came across this article. It talks about on site generation of the cleaning and disinfecting part ONLY of sodium hypochlorite w/o the chlorine smell!

Check it out! Wonder how much this equipment costs, and if it is feasable for our use ?

 

 

THE WALL STREET JOURNAL: ‘JUST ADD ELECTRICITY’

June 22, 2011

JUNE 8, 2011, 2:06 P.M. ET
Associated Press

NEW YORK — It sounds like a late-night infomercial: Kill germs and clean surfaces with nothing more than water and a few volts of electricity! Pay pennies a gallon! Strong enough to kill germs but gentle on your skin! The use of electricity and water to clean and disinfect has been embraced by some food and hospitality businesses looking to save money and go green by swapping out conventional products.
At busy Whole Foods on Manhattan’s Union Square, workers keep battery-operated spray bottles designed to keep surfaces clean with water packing an electrical charge. Also available are electrolyzed oxidizing water products, or EO water, which are cleaning systems that use salt and electricity to create solutions for cleaning kitchens, prison floors and hotel rooms.  No, these are not miracle elixirs.

While users of the two different types of systems say they save money, start-up costs are far higher than simply buying a bottle of bleach. They’re not suitable for every cleaning job, and different zapped water treatments can lose potency over time. Critics say some of the claims for electrolyzed water in particular — it’s touted as everything from a health drink to a skin treatment — are overblown. Still, studies have shown water exposed to a charge works as a cleaner.
“We use it everywhere,” said Mary Ann Flynn, appearance manager for the Culinary Institute of America in Hyde Park, N.Y. The school uses EO water. “They fill mop buckets with it. They fill bottles so that the students and the chefs use it in the kitchen.”
The electrolyzed water systems vary, but a common type creates separate streams of disinfectant and cleaner by
running a charge through water exposed to salt. The disinfectant stream mainly contains hypochlorous acid, a form of chlorine. Viking Pure, one of several makers active in the United States, claims its sanitizing solution is effective against a long list of pathogens ranging from listeria to swine flu virus. A big selling point of the machines it sells is that users make the cleaner on the spot so they don’t have to transport chemicals. Viking Pure’s president, Walter Warning, said the “acid water” is so gentle you can spray it on your skin. The same salt-and-electricity process also creates a separate stream of sodium hydroxide, a common ingredient in cleaners. This “alkaline” stream can be used as a general purpose cleaner and degreaser.

Deborah Stone, housekeeping manager for Carolina Designs rental agency at North Carolina’s Outer Banks, swears by it and said some of the biggest problems are convincing workers they can clean without suds. “It’s very difficult for the cleaners to comprehend that because there is no smell and because there are no bubbles, they don’t get the sense that they’re actually cleaning,” Stone said. “You still have those die-hard people that want the suds and the pretty smell.”
Academic researchers have found that electrolyzed systems can be effective cleaners and disinfectants when the process is done correctly.

Professor Ali Demirci of the Department of Agricultural and Biological Engineering at Pennsylvania State University has researched the use of EO water to decontaminate various food products and clean dairy equipment. He has found it works well for both cleaning equipment surfaces and killing bacteria. Professor Yen-Con Hung of the Department of Food Science & Technology at the University of Georgia has studied electrolyzed water for years and said it can be more effective than bleach in many cases. Researchers note that EO water performs best on smooth surfaces. Bassam Annous, a research microbiologist for the federal Agricultural Research Service, has found it does not work well ridding lettuce and apples of E. coli because the water-based solution cannot penetrate the minute crevices where the bacteria can lurk. “This is not a silver bullet,” Hung said. “EO water is not perfect.”

Bob Brown, who is in charge of food safety support for Whole Foods, said that a number of stores in the
mid-Atlantic and Midwest are starting to use the sprayers for cleaning glass and other surfaces, like conveyor
belts. “It’s better for the environment if you’re not using chemicals,” Brown said. “So it’s a green technology that’s
available.” How green? That’s hard to quantify precisely.

In the case of the electric spray bottles, there are no chemicals. Both the spray bottles and the EO water require
electricity, though not much. Activeion’s spray bottle runs on a rechargeable 12-volt battery. Bob Schildgen, aka Mr. Green, the environmental advice columnist at Sierra Club, said comparing a chemical-based cleaner to an electricity-based one is apples to oranges.  “It’s extraordinarily difficult to compare such different processes and come to a firm conclusion on it,” he said.

Chlorine – A Great Disinfectant!

December 16, 2010

There are distinct differences between a Sodium Hypochlorite solution, aCalcium Hypochlorite solution and an onsite generated Hypochlorous Acidsolution.

Sodium Hypochlorite Solution (NAOCL)

 

Sodium Hypochlorite solution often called bleach usually containing LYE is manufactured at a factory, stored, shipped to distribution centers, stored again and then sold.

Calcium Hypochlorite Solution (CAOCL)

 

Dry Calcium Hypochlorite tablets produce a “FRESH” Hypochlorite solution when mixed with water. In tests done, a solution produced with the proper Calcium Hypochlorite tablet, can maintain “Free Available Chlorine” or Hypochlorous Acid the
active disinfectant in this Calcium Hypochlorite solution, for ONLY about 4 hrs, then it starts rapidly degrading.

Hypochlorous Acid Solution (HOCL)

Until now, HOCl has simply been thought of as a transient byproduct in the ubiquitous chlorine chemical family. However, HOCl generated by ECA technology carries with it fewer negative hydroxides than the previous HOCl formed via disassociation from sodium hypochlorite. Because of this, ECA-generated HOCl behaves uniquely and must be considered separately from chlorine. HOCl as a stand-alone chemical, separate from chlorine, has not been available in the market until now. This breakthrough results in a need for a paradigm shift in biocidal approaches. HOCl is an “old”, well appreciated chemical but is now “new” availabie as onsite generated solution.

 

 

1. Free available Chlorine content

For a chlorine solution to be a good disinfectant it must meet the Chlorine Demand. The chlorine demand is the amount of Free Available Chlorine (FAC) often called Hypochlorous Acid (HOCl), needed to disinfect or oxidize organic matter before a FAC residual is reached. If the chlorine demand is not met then complete disinfection has not been obtained. One of the best signs that the Chlorine Demand has not been met is the strong chlorine odor.

If a chlorine solution is does not contain enough HOCl to satisfy the chlorine demand of the surface or product to be disinfected, chloramines will form as chlorine and nitrogen-based materials combine. Examples of nitrogen-based materials are proteins and blood. Chloramines are responsible for the obnoxious odor sometimes associated with chlorine disinfection. The obnoxious, pungent, eye-stinging smell of chloramines, mistakenly identified as free chlorine, indicates that the chlorine/water mix is not effective. There is not enough HOCl to satisfy the chlorine demand

2. Chlorine Efficacy determined by pH

Chlorine in water splits into two forms, Hypochlorous Acid (HOCl) andHypochlorite Ion (OCl-). At the high pH the chlorine provided by bleach contains a maxiimum of Hypochlorite Ion. The chlorine produced by onsite Electrolyses in an Aquaox System contains a maximum concentration ofHypochlorous Acid (HOCl).

How much of each is present in a chlorine solution is totally dependent upon the pH of the solution. As pH rises, less Hypochlorous Acid and moreHypochlorite Ion is in the solution. As the pH rises, less germ killing power is available. According to a University of Illinois study, HOCl is 120 times more effective as a sanitizer than the -OCl ion. The ideal pH of a disinfecting chlorine solution is a pH of 6-7.

Most FRESH Calcium Hypochlorite solutions have a pH of between 7 and 8.  ALL (fresh or old) Sodium Hypochlorite solutions, (“bleach”) have a pH of 10.25+ producing NO HOCl at all! These solutions produce only the OCl- ion, a very poor disinfectant which is from 80 to 120 times less effective as a disinfectant than HOCl, providing that there is any chlorine left in the stock solution.

3. Contact time

The amount of time that chlorine is present during treatment is called the contact time. Contact times are calculated to determine the amount of time that a disinfectant must be present in the system to achieve a specific kill of microorganisms, for a given disinfectant concentration. A long contact time  means that disinfection alone will not be sufficient treatment and additional methods will be necessary to eliminate the microorganisms.  The contact time is directly related to the chemicals’ efficiency of eliminating bacteria and viruses from the water. HOCl requires by far the shortest contact time to achieve a 99% kill of E. coli(Reynolds, 1996).

4. Shelf-life and added lye

Finally, just as champagne or carbonated water “go flat” on sitting as the bubbly carbon dioxide gas escapes into the air, chlorine escapes from aHypochlorite solution thus weakening its germ killing value. In order to slow this escape, bleach manufacturers add Sodium Hydroxide (lye) to their product causing the pH to rise dramatically. Lye burns animal and plant tissues; it saponifies (converts) fats in poultry and meat products.Hypochlorous Acid dispensed from Aquaox Systems contains NO LYE!

According to all the technical literature, depending on storage conditions; ALL Hypochlorite solutions will lose half of their potency in less than thirty days. Light, temperature and age are the biggest factors.  The biggest misconception is that liquid household bleach (Sodium Hypochlorite) does not loose potency until you make a Sodium Hypochlorite solution; “liquid household bleach” is already a Sodium Hypochlorite solution, that starts degrading soon after manufacture, so a “bleach” bottle bought at a retail store or chemical supply house is, NOT a FRESH Hypochlorite solution. It is a Hypochlorite solution with an unknown chlorine content, so when we make a solution all we are doing is diluting an already weak Hypochloritesolution even more. All literature recommends that if you are using “chlorine bleach”, daily tests should be conducted by a laboratory to assure its potency.

Why Use onsite produced Hypochlorous Acid solutions instead ofCalcium or Sodium Hypochlorite solutions?

1. Onsite electrolyses of a brine solution in Aquaox Systems produce a maximum of Hypochlorous Acid whereas pH can be accurately set and controlled anywhere between 3-7.

2. At an pH of ~5 the Hypochlorous Acid solution consist almost solely of Free Available Chlorine and maximum disinfection is achieved.

3. Hypochlorous Acid requires the shortest contact time to eradicate a microorganism.

4. As Hypochlorous Acid is produced onsite, there is no need of mixing and dilution of Hypochlorite solutions with unknown chlorine content. Shelf life is no issue, as Hypochlorous Acid solutions are produced on demand. Therefore no addition of Lye is required, as shelf life became more or less irrelevant.

CHLORINE EFFICACY

January 27, 2010

Introduction

Chlorine is one of the most commonly used disinfectants for water disinfection. Chlorine can be applied for the deactivation of most microorganisms and it is relatively cheap. Chlorine is commercially available as gaseous Chlorine (CL2) and as Sodium Hypochlorite liquid or powder (NaOCL).

Both gaseous Chlorine (CL2) and Sodium Hypochlorite (NaOCL) have very limited disinfecting properties. It is the formation of chlorine by-products such as Hypochlorous Acid (HOCL), Hypochlorite Ion (OCL-), Hydrochloric Acid (HCL) and Oxygen (O) that inhibit disinfecting properties.

Gaseous Chlorine

Gaseous Chlorine (CL2) is commercially available and mostly used in disinfecting mains water.
When gaseous Chlorine (CL2) added to water (H2O) the following hydrolysis reaction takes place:

Cl2 + H2O = H+ + Cl- + HOCl

Sodium Hypochlorite

Sodium Hypochlorite is produced adding gaseous Chlorine (CL2) to caustic soda (NaOH). When this is done, Sodium Hypochlorite (NaOCL), water (H2O) and salt (NaCl) are produced according to the following reaction:

Cl2 + 2NaOH + → NaOCl + NaCl + H2O

Chlorine reacts with sodium hydroxide to Sodium Hypochlorite (NaOCl). Sodium Hypochlorite is known as Bleach. Bleach (NaOCL) cannot be combined with acids. When NaOCL comes in contact with acids the hypochlorite becomes instable, causing poisonous gaseous Chlorine (CL2) to escape.

Hypochlorous Acid and Hypochlorite Ion formation

Hypochlorous Acid (HOCL) and Hypochlorite Ion (OCL-) are the by-products of Sodium Hypochlorite (NaOCL) in water (H2O). NaOCL reacts with water (H2O) to Hypochlorous Acid (HOCl) and Hypochlorite Ions (OCl-).

NaOCl + H2O → HOCl + NaOH-

Hypochlorous Acid formation

Hypochlorous Acid (HOCL) is the by-product of gaseous Chlorine (CL2) in Water. Gaseous Chlorine (CL2) reacts with water to Hypochlorous Acid (HOCL).

Cl2 + H2O -> HOCl + H+ + Cl-

Oxygen formation

Depending on the pH value, Hypochlorous Acid (HOCL) expires to Hypochlorite Ions (OCL-).
Cl2 + 2H2O -> HOCl + H3O + Cl-
HOCl + H2O -> H3O+ + OCl-

This falls apart to Chlorine and Oxygen atoms:

OCl- -> Cl- + O

The efficacy of disinfection is determined by the pH.

Disinfection will take place optimally when the pH is between 5 and 7, as then a maximum of HOCL is present.
HOCL reacts faster than OCl- ; HOCL is 80-100% more effective than OCL-. HOCL does not evaporate and does not cause severe corrosion like CL2. CL2 exposed in air can be very explosive and evaporation should be avoided. For this reason, the ideal pH is between 6 and 7, as no CL2 is present.

The level of HOCL will decrease when the pH value is higher than 5. The level of HOCL will decrease when the pH value is lower than 5. With a pH value of 6.5 the level of HOCL is more than 90%, whereas the concentration of OCL- is less than 10%.

Free Available Chlorine

Free Available Chlorine (FAC) is chlorine that is present in the form of Hypochlorous Acid, hypochlorite ions or as dissolved elemental chlorine. FAC includes all chlorine species that are not combined with ammonia (or other nitrogenous compounds) to form chloramines. It is ‘free’ in the sense that it has not yet reacted with anything, and ‘available’ in the sense that it can and will react if needed.

A pH value of 6 to 7 is the most effective and the safest pH-range, due to absence of chlorine gas. Therefore when Free Available Chlorine is mentioned, it is assumed that Free Available Chlorine solely consists of HOCL and OCL-

Free Available Chlorine compounds with regard to pH .Hypochlorous Acid (red) and Hypochlorite Ion (green)

Superiority of Hypochlorous Acid compared to Hypochlorite Ion

Hypochlorous Acid (HOCl, which is electrically neutral) and Hypochlorite Ions (OCl-, electrically negative) will form Free Available Chlorine (FAC) when bound together. This results in disinfection. Both substances have very distinctive behavior.

The cell wall of pathogenic microorganisms is negatively charged by nature. As such, the cell wall only penetrated by the neutral Hypochlorous Acid (HOCL), not by negatively charged Hypochlorite Ion (OCL-).
HOCL can penetrate slime layers, cell walls and protective layers of microorganisms and effectively kills pathogens as a result. The microorganisms will either die or suffer from reproductive failures.

The pH neutral Hypochlorous Acid (HOCL) can penetrate cell walls of pathogenic microorganisms whereas the negatively charged Hypochlorite Ion (OCL-) cannot penetrate cell walls.

Besides the neutrality of HOCL, it is a much more reactive and is a much stronger disinfectant than OCL-, as HOCL is split into hydrochloric acid (HCl) and atom air Oxygen (O). Oxygen is a very powerful disinfectant.

Neutral Electrolyzed water (HOCL) guarantees optimal disinfecting

The disinfecting properties of Chlorine in water are based on the formation and oxidizing power of Oxygen and HOCL. These conditions occur when the pH is between 6 and 7.

Neutral Electrolyzed Water (NEW) produced onsite from a AQUAOX System has a pH of 6.5. At this pH more than 90% of the free available chlorine is HOCL, less than 10% OCL- and no CL2 are formed. The strength of Free Available Chlorine (FAC) in NEW is pre-set to 300+ppm. To make a solution with 300+ppm FAC from commercially available bleach (NaOCL), it is diluted in water (H2O).

The problem with diluting bleach in water is twofold:

1) The volume to dilute bleach is very small. Small differences in the volume of bleach added to water causes significant differences in terms of pH and Free Available Chlorine (FAC).
2) The fact that water has naturally different pH levels, causes that addition of the same volume of bleach still result in a different pH. Although at each dilution 300+ppm FAC can be measured, the pH of the mixture and consequently the amount of active compounds HOCL and OCL- may vary considerably.

Therefore, disinfecting properties using bleach vary whereas the disinfecting properties of NEW are kept stable. As a result NEW may exceed the disinfecting properties of bleach by 300 times.

Safety

When producing HOCL by acidifying NaOCL, relatively high prices and possibility of side reactions limit the use of weak organic acids; use of cheaper inorganic acids provokes gaseous chlorine discharge and a raise of toxicity level. Because of it, the method above is only used for water treatment, where residual chlorine concentration values do not exceed 0.5-5mg/l.

Dilution of gaseous chlorine in water to produce HOCL according to equation demands special safety measures and is only used for disinfecting large volumes of water, where active chlorine concentration is below 10-15mg/l. Nowadays all the companies that manufacture gaseous chlorine stopped gaseous chlorine production and started NaOCL manufacture exclusively because of safety considerations.

Neutral Electrolyzed Water onsite produced by AQUAOX Systems is a unique method of non-reagent synthesis of HOCL. We would like to point out once more that the unique quality of the AQUAOX System is the possibility of directed pH regulation in the 6.0-7.0 ranges, while working with solutions of any mineralization, whereas electrolyses of sodium chloride solutions have identical biocidal activity if pH and FAC concentration are equal.

 Very good read! I read about 3/4 of it.

 

Everything makes sense with what I've learned here.

I wish the guys from Aquaox would come on the forum like they said they were going to, and answer some questions.

It is NOT clear to me if this machine can generate cleaning water of the type us roof cleaners want.

This would be great! No more SH in the eye. No more rotten hose reels. No more wearing half face masks. It sounds like we would still have to bag down spouts and water plants.

I aint buying in until i see real world results. I spend just about 7-9 thousand a yr on chemicals and it would be a nice return after 3-4 yrs if it works but i am pretty sure it wont for our application. I hope i am shown differently thought.

From what I have seen, so far, it will not generate the hypochlorite ION on the alkaline side of the reaction. Instead, I am told it generates sodium hydroxide water, fine for carpet cleaners, but not for us.

To add to what Gary said,..our final mixture is approximately 3-5% for shingle strength. So if you can get your generator to kick out 3-5% sodium hypo equivalent,.. and after some "in the field" testing by a few of us here, people there will be interested.

From Ralph Lambert - Tech Guy from Aquaox. To Chris Tucker & others who have responded. Yes, some machines produce 2 products - HOCl & NAOH [sodium hydroxide]. Others will produce only HOCl in the 7 to 9 pH range. If you are now using Sodium Hypo what % is it - 5% or 12%. Household stuff is 5 to 6%. What dilution is used - how many oz/gallon of water ? With that info I can offer some better comments. Thanks ral

 Most everyone uses 12.5% SH in a 30-40% mixture.  (100 gallon mix requires 30-40 gals of SH)

 As you know, at alkaline PH, Sodium Hypiochlorite gives the hypochlorite ION, it is the ION that gives us the cleaning power to remove Algae (organic matter) from roof surfaces.

I have heard some SAY that at lower ph, sodium hypochlorite will give the hyperchlorus acid that is 100 times as good of an oxdizer as the hyperchlorite Ion is ? But, will this clean roofs as well as the Ion will ?

I am sure for disinfecting, the hyperchlorus acid is best, but we want cleaning capability!
