View Full Version : Alternative To using Chlorine Bleach to Sanitize your Fresh Water System - Purogene

Hello Everyone,
I want to share something I never knew until recently. There is an alternative to using chlorine as a sanitizing agent for cleaning your tank.
Using chlorine dioxide for sanitizing your fresh water system is a superior alternative to using bleach. There is a product called Purogene (http://rvwaterfilterstore.com/H0027.htm) that not only kills the bacteria, but it also removes the bio-film left in the pipes and the tank, and you don't need to flush the system out three or four times after sanitizing to get the smell and taste out. Chlorine Dioxide is used to sanitize airline water systems and is EPA approved for drinking. Because of this, you can use it directly in your tank at a low concentration to prevent bacteria growth if your tank goes unused for a period of time. If you would like more info, here is a video (http://www.youtube.com/watch?v=Y7DsAeQ6ujQ)from the manufacturer that explains it better than I can.

Interesting info. As I use my fresh water tank for 100% of our water needs, I am interested in using something other than bleach.

Attaching some directions for using Purogene from their website.

Did the website change? Looking with an iPad I can’t find items I found last week using a laptop. One of the triple filters was listed as being good for drawing lake water, ‘south of the border’ IIRC.

Using a filter system like that, will the purogene diluted mixture make it through the filters if they are plumbed after the water intake?

My current setup, twin filters inside the basement, nothing goes in the trailer from either the winterizing valve or the city fill without going through the filters. I also use my winterizing valve to fill the trailer tanks from a portable source (I have a 28 gallon water tank for boondocking purposes)

Currently when I do the bleach thing I have to remove my carbon filter element.

Jim, when you install your triple jumbo filters, could you ‘yardstick’ the installation to show the required space needed?

Sure thing. They are huge! I used a 3/4” NPT to 1/2” PEX bard elbow on the in/out to minimize the width. I’ll measure it up later today and add the dimensions to my image gallery.

You can run the diluted maintenance dose through the filters no problem, but you should take out the carbon or reverse osmosis filters when sanitizing the system.

I have rearranged some of the systems on the website, but everything is still there. The search engine on the store is pretty good, so if you search for what you are looking for, you can usually find it with a search, such as "south" for South of the Border. If you have trouble finding anything, you can always ping me on CONTACT US and I will help you out.

Has anyone ever thought of using an Ultraviolet Light Disinfector post the storage tank or water pump? It could even be switched on by the water pump activating with some simple circuitry. No chlorine (Weapon of mass destruction) used in this solution.

You can certainly use UV to sterilize your water after the tank. The link above is for 1/4" tubing and 1 gallon / minute. We sell UV lights at 2 GPM, 4 GPM and 6 GPM with 1/2" fittings. I have a few concerns with UV light. 1- They use power, 2- They use glass and quartz bulbs and tubes that can be fouled or broken, and 3 - They need to be replaced yearly. UV-LED is becoming more popular, but it is quite expensive.

Dave, I can’t find it now, but somewhere I saw on your site that using the ‘South of the Border’ filters would be good enough to use lake water to fill th fresh water tanks.

Is that filter set good enough to make lake water drinkable?
if not would using the Purogen be suitable enough to make the water drinkable?

And then finishing it off with the under sink filter kit?

Any issues using purogene and a water softener? Most sources up here are hard water and I fill with a filter and then softener? All are municipal or regulated water sources treated prior to park distribution.

No issue at all. They are doing two different things, so the water that you put into your tank will have less calcium and magnesium, which would have no effect on the Purogene.

The main concerns about drinking water from lakes and rivers are pathogens, sediment and unknown chemicals. The Doulton RIO 2000 will remove all bacteria and cysts and virtually all viruses and sediment down to 0.5 microns. Some free floating viruses may be able to get through, but these should be very few. The KDF/GAC filter will remove chemicals, chlorine, taste/odor, lead and heavy metals. Purogene in the tank will take care of any viruses that get through. The Ultrapure Premium system under the sink will get fluoride, lead, arsenic, and take more of the chlorine, chemicals and taste/odor issues. In other words, this system would allow you to drink virtually any water safely.

I've never used that position, but according to Anderson Brass, seems like it should work:

Four Positions, Four Functions
City – Pressure feed fixtures from 3/4" hose connection on backflow preventer.
Normal – Pump from the on-board tank to the fixtures using on-board pump.
Tank – Pressure fill the tank from 3/4" hose connection at backflow preventer. 100 gallons
in 7 minutes.
Sanitize/Winterize – Draw in sanitizers and winterizing fluids from a bucket utilizing the
on-board pump.

I'm under the impression that the winterizing position connects the water inlet to the suction side of the pump so that antifreeze can be routed through the pump and on to all the fixtures. I think the only way to get fluid into the fresh tank is with the TANK setting.

Bleach or alternatives can be poured into an empty water hose. Then connect the water hose to the water inlet and water faucet. The water pressure from the faucet will push the bleach/other stuff into the tank. Then when ready to introduce the diluted mix to the pex lines and fixtures, switch the Anderson Valve to NORMAL and turn on the pump.

That was my understanding as well.

I have also been trying to figure out how to get sanitizing solution into the fresh water tank without a gravity fill. I am going to try using a small water pump (powered by a drill motor) to pump diluted solution from a 5-gallon bucket into the tank with the TANK setting.

If your rig uses a water filter, then take out the filter a pour the sanitizer into the filter tank. Reconnect and your good to fill your tank. Run water throughout the rig using the pump and your good to go. Yummmm...fresh water. :rolleyes:

I posted my question considering I have the ‘old school’ intake system. A separate winterizing valve. Using that valve I can draw water from any source and direct it to the house systems or the tank.

The filter idea seems like a good ‘solution’ for your ‘dilution’, especially if you have a spare housing laying around.

Or, there are several pump strainer-filters they may be suitable for the small amounts of Purogen needed.

Just add some quick connects or 3/4” hose to 1/2” pipe fittings (Home Depot)

And for those that are resourceful, couple of PEX or Sharkbite fittings, 1/4 turn valve, installed in the right places and you could use the Anderson might leak valve winterizing position and pump into the tank.

You might be on to something. Adding a connection to the water line that goes to the tank after all the valves. This would make a gravity fill line for the solution. Have to think about this a bit.

I’ve ordered the Purogene, but will have to wait on using it until we get the rig to our summer site next week. Today I’ll be clearing the AF out of the lines and pumping in several gallons of clean water from jerrycans. Don’t have a water source at the storage yard and have the older gravity fill for the tank.

Reinstalled the TV’s and brought some other goods out to the rig yesterday.

5/1/2018: Got a note from Dave that due to all of you ordering Purogene, my order will be slightly delayed. No biggie, can't use it for a while, anyways. On another note, the dewinterizing went easily. First used air to drive the AF out, then used the water pump to draw 15 gallons of clean water through the lines and out all of the faucets and low point drains. Checked the Sailuns and they were all at about 105, to I topped them to 110 and installed the TST 507 sensors. The receiver has sat in a box all winter, yet showed a full battery charge when I turned it on and picked up the four tires quickly.

Dumped several gallons of water into the black tank via the toilet and added some "Geo" mix to it. Should get sloshed around when I haul it north next week.

This method actually worked to get the sanitizing solution into the fresh water tank. I followed these steps:

Filled the fifth wheel fresh water tank about 1/3 full with fresh water.
Put about a gallon of water in a 2 gallon bucket for a test run.
Connected the output side of the drill pump ($3.99 at Harbor Freight) to a hose then connected the other end of the hose to the Andersen fill valve.
Connected a short piece of hose to the input side of the drill pump, primed the pump, then put the short hose into the 2 gallon bucket.
I had to experiment with the drill direction and speed to get it to pump. Then it pumped just fine.
Then I mixed the Purogene solution with lemon juice and let it set 5 minutes.
And then pumped the activated Purogene solution into the Bighorn fresh water tank.
Then I topped off the Bighorn fresh water tank and finished the sanitizing process.

Spring Fresh is a completely different compound that contains Ethylalchol, Sorbitan Monooleate Ethoxylate. I am not sure how to use it or what it's effectiveness is, but it sounds like it is similar to an alcohol swab for your water and is not EPA approved for ingestion.

He has a great selection of rv products for water use and an even bigger knowledge of how to apply them. We have bought hoses (high quality drinking hoses) a high grade pressure regulator (watts) water filtration canisters and now the Purogene. Anxious to get my water system cleaned. We move around a lot and I know that water quality is not the same at them all.

To fill fresh water tank without a city water connection, I added a 2nd 12volt water pump in the UDC.
I pump the water out of a Blue Colored water jug I have, turn Anderson valve to tank, hook hose up to city water inlet and pump into the tank.
I taped into the 12volt power off the light in the UDC and added a switch for the pump.
Works like a charm.
I removed this system from my Big Country before I sold it.

Sodium Chlorite is a precursor to produce Chlorine Dioxide. It doesn't magically do this by itself. You must use chlorine or acid to activate it. Left to dry out it will spontaneous combust. Commercially it is supplied in as low as 3% solution for small applications and at much higher concentrations for large applications. If you do let it dry out and hit it with some acid you will be dead in a hurry if you breathe it. You can make a lot of money cutting the industrial version with water and reselling it. The lower percent watered down product is sold that way due to the fire hazard and environmental hazards as well of the concentrate.

Chlorine Dioxide gas in water is an excellent biocide and will remove biofilms while killing more bacteria than chlorine. However it is very lethal and dangerous and must be generated on site and is never transported. Google it and see how lethal actual chlorine dioxide is. It is also very easily gassed of and doesn't remain in the water very long.

I worked with chlorine dioxide generators on a large scale for many years and you don't buy it in a bottle or any other type container.

You are buying a little over 0.0335% sodium chlorite salt. (not sodium chloride) this is based on the MSDS dated 1994 on file by the parent company. Note the .1 ppm used rate as well on the MSDS. Supposedly 0.2% Citric Acid for the activator is added but don't show up in the SDS which is the replacement for the MSDS sheets of old.

I use hydrogen peroxide and just add it to the tank when I fill it based on the amount of water added. Bleach does have its drawbacks but there is no magical product out there that is safely and easily applied or the world would be using it.

This product can work on a limited scale but it is hardly anything new or magical. To sum it up a bottle of hydrogen peroxide will do the same thing and is a bit cheaper.

Do a little home work and see what you are investing in. I don't like to rain on any ones parade but this one is in a very grey area.

JohnDar
07-31-2018, 02:42 PM
And what volume and concentration of hydrogen peroxide are you using. The stuff in the drugstore is 3% H2O2. Reagent grade is 30% or more.

On another note, I’m doing the Purogene procedure on my tank. Literature said this rig held 75 gallons of fresh water. According to the meter on the fill hose, the tank only holds 60 gallons. So that means they calculate the water heater (12 gallons) and the plumbing into the equation.

Hi. My name is Tracy Presnell and my wife and I own 3R Odor-Con/Purogene Sales and we are the North American/Canadian distributors of Purogene. Dave sent me the text of this post and I requested that he allow me to respond to it since we are the "factory" when it comes to Purogene for RVs and Boats.

You do have some things right. Sodium Chlorite is a precursor for the production of Chlorine Dioxide but Purogene isn't just Sodium Chlorite in solution. There are other stabilizing ingredients in the Purogene formulation to tailor its reactivity. Purogene can be used activated with an acid (citric acid or lemon juice) to release the available Chlorine Dioxide for system disinfection. Or, it can be used un-activated as residual protection for bacteria. The bacteria themselves are acidic and when they encounter the formulation there is a release of Chlorine Dioxide to kill the bacteria. Because it's in a stable form, the remainder of the formulation stays in solution and remains un-activated until it encounters additional bacteria or something acidic. The by-product of reacted Purogene is ordinary table salt.

If you are able to remove all the liquid from Purogene it would not spontaneously combust. It would be pretty reactive, but it will not combust on its own. And, there's not going to be much of it. Generally speaking, it's actually a lot safer and much less toxic than bottled bleach.

Purogene has 2% (20,000 PPM per ounce) of available Chlorine Dioxide. It is not Chlorine Dioxide in a bottle. It is available Chlorine Dioxide.

You are correct in that Chlorine Dioxide is an excellent biocide and removes biofilm while killing more bacteria that chlorine. You are also correct that Chlorine Dioxide gas is always made on site and cannot be transported. But, again, Purogene is not Chlorine Dioxide, it is available Chlorine Dioxide. In the activated form (mixed with acid), Purogene in an uncapped bottle will last about a week. In a capped bottle, about a month.

As for the MSDS, you have a few things incorrect. It's actually 3.35% Sodium Chlorite. There is not a .1 PPM used rate as you state. The .1 PPM and .3 PPM limits are for exposure. The only time those limits are even an issue is during activation (after adding the acid). They have nothing to do with Purogene in water. When you activate Purogene there will be a release of Chlorine Dioxide gas and you should not hold you head over the container. But, the amount of gas release is small. You would almost have to concentrate it intentionally for it to be an issue. The new SDS doesn't even have those limits stated. The recommended residual available Chlorine Dioxide for drinking water treatment is 5 PPM (1 ounce in 30 gallons of water).

Hydrogen Peroxide is a pretty poor disinfectant unless you bring the level up high enough to be somewhat effective. What you get in the brown bottles is generally 3% HP. If you were able to fill your entire tank with 3% (30,000 PPM) HP you would kill some of the bacteria. For the tougher ones you have to about double that concentration to 7% or 70,000 PPM. For the really tough ones you would need closer to 27% (270,000 PPM) to be as effective as 50 PPM of activated Purogene for the same types of bacteria. You can buy 35% HP but you're gonna need a whole lot of it to actually do something. HP isn't used in water disinfection by itself, it's always paired with another process because it's a weak mirobiocide. It is not approved by regulatory agencies as a stand-alone disinfection treatment process.

Purogene is just about the most effective disinfectant available. It deals with the hardest to kill bacteria and does so with a very mild by-product: table salt. There really isn't much grey area as it has been tested side-by-side with other common disinfectants and shown to be incredibly effective when compared to other disinfectants, some of which have to be used at very high concentrations and some of which produce some very bad by-products. It's EPA registered and has been used in the airline industry for nearly 40 years to disinfect the tanks in airplanes of all sizes and the equipment used to transport water. Virtually every airframe manufacturer specifies only Purogene to maintain the water systems in the planes.

I hope I've been able to clear up a few things up.

Do a little home work and see what you are investing in. I don't like to rain on any ones parade but this one is in a very grey area.

Hi. My name is Tracy Presnell and my wife and I own 3R Odor-Con/Purogene Sales and we are the North American/Canadian distributors of Purogene. Dave sent me the text of this post and I requested that he allow me to respond to it since we are the "factory" when it comes to Purogene for RVs and Boats.

You do have some things right. Sodium Chlorite is a precursor for the production of Chlorine Dioxide but Purogene isn't just Sodium Chlorite in solution. There are other stabilizing ingredients in the Purogene formulation to tailor its reactivity. Purogene can be used activated with an acid (citric acid or lemon juice) to release the available Chlorine Dioxide for system disinfection. Or, it can be used un-activated as residual protection for bacteria. The bacteria themselves are acidic and when they encounter the formulation there is a release of Chlorine Dioxide to kill the bacteria. Because it's in a stable form, the remainder of the formulation stays in solution and.......

Thanks for chiming in Tracy!

What did I use high concentration hydrogen peroxide for? Mixed with formaldehyde, I converted sodium cyanide plating waste to the cyanate form so it could be dumped. Was called the “Kastone Process.” Nasty cadmium plating process.

I had considered sanitizing my coach's water system soon and was spurred on to do so by this forum thread (https://heartlandowners.org/showthread.php/73048).

I already had the Purogene on-hand and it was just a matter of getting it done. So here's a summary of what I did:


Drained, filled, then drained again, the tank to do an initial clean water flush of it
Added activated Purogene to tank, filled with water and allowed it to sit for an hour
Drew Purogene water from tank through entire plumbing system and every fixture
Drained Purogene water from tank and produced 80 gallons of RO water into tank

Pretty easy to do and no smell. Here's a link (https://www.rvwaterfilterstore.com/H0027.htm) to purchase the Purogene product from our HOC Partner, RV Water Filter Store. Buy 2 quarts to get free shipping and use HOC discount code HEART18 to get another 15% off your order.

When we are done traveling for the season, I' going to sanitize my home water system with Purogene too.
