Water Disinfection For The Food Industry

Disolve ozone into the water.

It will kill any living organisms. There is already a commercial kitchen device that does this that is available. WWW.tersano.com

This is somewhat off the question asked but I think it is worth raising. I have seen ozone O₃ used for swimming pools as well as tanks for marine mammals and reptiles like dolphins an turtles instead of chlorine and it seems to be a better option. I am curious however about the ability of O₃ to destroy all infective substances. It will defiantly kill anything that is living in the water but can it destroy all virus particles and prions?

Virus particles aren't really alive, they are just a piece of genetic material that uses other organisms that they infects to reproduce so are dormant and some are extremely difficult to destroy. Prions are deformed proteins that after infecting an organism hijack existing proteins to replicate themselves. CJD and Mad Cow disease are caused by prion infections. Prions are nearly impossible to destroy and it only take 1 of the little buggers to slowly kill you.

If you really want to steralise the water use high powered UV germicadal fluorescent tubes in sealed watertight enclosure...

This is the standard way to kill off anything in the water, including human tissue etc...

As for prions, as masu said they aren't living and are merely a protein so they are little sods to get rid of...

Disinfecting water with Ozone is a very effective and efficient method (this is a possible green method for the future, rather than chlorine and other additives - The French have been using it for years). But remember that the absorbtion rates and effectiveness will vary greatly as the flowrate, ph, temperature and injection methods vary. The device to generate the ozone should be matched to the process as well as the medium to be sterilized. Also remember that O3 will only remain in situe for a short period of time and will ultimately become O2 once again, so the handling of the sterilized product after the process will once again effect its sterility. BEWARE of CROOKS selling bottles of Ozone!! Their is no such thing. Ozone is either generated through carona discharge or an Ultra Violet process. It is unstable and cannot be stored for long periods. The usual transfer method is a venturi valve and the size and efficiency of the generator dictates the amount of Ozone avaliable for absorbtion. Bear in mind, that by using Ozone to sterilize food stuffs and liquids for human consumption, you increase the shelf life and "sell by" date. You also cut down on Sodium Benzote and other traditional additives, thereby lessening(sp) flavour taints, after tastes and respiratory complaints. So it's good all round.

Enough ozone will actually oxidize all organics present, so it should take out viruses and prions, and even break down organic contamination in the water.

Have you got any empirical evidence that O₃ is capable of destroying all virus particles as well as the prions? From what I have read about prions there is nothing much short of a thermo nuclear device that is guaranteed to destroy them. I know they will survive autoclaving, gamma ray irradiation, incineration and just about anything else you can throw at them.

It all depends on how much water what flow rate you want per given time and at what cost. Where are you getting your water from. Can you give some more information. To what standard will you product be tested? Is the water included in the final product or used as a cleansing agent. Can you use steam?

Chlorine can be used then neutralised by ozone. Ultraviolet light can be used where it will not affect the other processes. Many plastics will be adversely affected by high power ultraviolet light.

Initial guest

I have 2 tanks conjugated (means that they work as one) containing 6 m3 each. I get the water from a well which means that it is not citywater (which is already chlorinated). Yes the water is included in the final product, this is why I need to be sure about its quality.

I also reply to another question about filtering. I currently use active carbon filters but the initial water I take is city water. I can't tell you that I am sure about its quality, reffering to the high standards and the strict laws in food industry. Anyway, we are currently moving to new premises and we are no longer able to use this city water and the nearest one available is this water from the well.

Here in Bali we have a lot of success disinfecting drinking water and pool/spa water with a replacement to chlorine:colloidal silver producing units installed in the flow line. This, together with a 1 micron filter provide good tasting water. Of course, it still has chlorine in it.

Ian Lyons produces Skalar Energy (see Tesla) shells which are installed around pipes. These are of huge benefit here where our water is very high in calcium. The shells also lock in sulphur smells from groundwater.

My first question to Guest who started this thread is what filtration size are you trying to achieve.

Also to those in this forum: I am really against reverse osmosis units for several reasons. If you use RO water on plants here, it kills them. Same with fish in a tank. One school here with a RO unit donated some years ago by a charity has had a 300% increase against the norm in tooth cavities. The Malaysian Armed Forces recently removed them from their camps and bases for the same reason.

I am interested in you statements about water purified with Reverse Osmosis units. Do they add fluoride to the water there as it sounds like the RO units are taking it out hence the increase in tooth decay? Do you have quantitative evidence of why the water from the RO units kills fish and plants? All the scientific tests I have read to date point to the water from RO units being better than most tap water especially when it comes to traces of estrodials. There was a debate here in Australia over using recycled water from RO plants and one of the concerns was the presence of things like paracetamol and estrogen in the recycled water. Ironically when tested the RO units had lower levels of both these than the existing tap water.

I have to agree with the comments on RO water, it's expensive and not the answer. I'm also keen to read your reply on whether Fluoride is being added to your water. If the RO process is removing this, tooth decay is definately on the cards along with other snags. Ozone is a far more efficient and cost effective way to sterilise water (and no I don't manufacture or sell Ozone generators). Large generators used in conjunction with the normal sand & pebble process, yield a far better quality final product.

I have seen magnetic (isotope) sheets being used for the rearranging of molecules in the wine and beer industry, is this similar to the "Skalar Energy shells that you are talking about? Would you mind telling me a little more about the "collodial silver" producing units.

Here's a source for ozone generators, if you're interested.

It depends on the application and stream. Some applications use peroxides, very strong disinfectant that maintains residual. Hypochloites might be applicable alone or in combination with ozone. Ozone affords no residual disinfection. Ozone require large amount of electricity, in essence you have a lightning generator in a cylinder.

For the large water works applications, yes Ozone Generators do draw a fair ampage - but weighed up against the cost of filtration and the quality of the final product, it's cheap. In smaller bottling machines and for domestic use, they use very little energy.

One thing that I have not mentioned is that of course OZONE IS TOXIC to humans!. Breathing in the O3 can effect the respiratory system and damage oxygen bearing cells and tissue. But, properly installed in the right application it is the answer. "Electricity is dangerous and can kill if not properly used - but it's in everyday use by millions of people". Is there a difference?

I have recently undertaken some studies using Ozone to retard the production of ethalene (the substance that makes fruit ripen). The introduction of the correct concentration of ozone into storage cold rooms inhibits the production of the ethalene, which then allows the fruit (in this case apples) to be stored for longer periods at higher temperatures (ie energy saving). It can also be used to kill mosqueto lava in swamp and dam areas reducing the level of Malaria infection cases. Once again, nature holds the key to solving our problems. Ozone can be used to disinfect wounds and promote healing, especially with open sores and burn tissue, but these are only in the test phase and still need to be given the green light by the proper medical authorities (however long that might take!) Could it be used to target and destroy specific cancer cells? Only time will tell...

There are many options for disinfection in water, but the biggest problem in my opinion is how to monitor this growth and get immediate feedback. Waiting a day or more for culture test results is much too slow. You don't know you have a problem until it's too late. Does anyone have any better ways to monitor microbial growth?

The pharmaceutical industry uses the blood of a horseshoe crab to test for bacteria. Evidently it clots in the presence of any sort of infective matter so if you add a drop of the blood to a test sample and it dissolves without clotting then its ok, if it clots then its not.
