I came across this product AQUA SALVEO for water purification. Just wondering has anyone used this product OR any other product to do this job.

My boat has been sitting for 4 years now and I suspect the water is maybe older than that. I can't remove the tanks without some major demolition and reconstruction work so is this the best alternative adding a few drops (and testing it on someone else).

Suggestions please.

See Ya

We have been using this product in our drinking water in our home for three months. My wife drinks at least 8 glasses of water daily and has for many years suffered from what was suspected as "irritable bowel syndrome". This "syndrome" cleared after about 10 days of this water treatment, completely.

Aqua Salveo is simply IONISATION of water - a well documented process of purifying water. Ionisation was until recently done with an electrical process that required expensive equipment and difficult to use on a boat, etc.

Treating the tanks with Aqua Salveo will kill EVERYTHING growing in the tanks but you will be left with all the "solids' floating. So, my suggestion is to treat the tanks with Aqua Salveo, leave for a day and then flush the tanks a couple of times to remove the solids. Then, fill & treat with Aqua Salveo. There is no unpleasant taste or smell and the stored water will remain sanitised for as long as two years. This treated water will remain sanitized - no "growth" and best of all, no chlorine or bleach to damage the plumbing. Once clean, the tanks (or containers) will stay clean and sanitised with this treatment.

This should also be used in the water from a watermaker as the watermaker will desalinate but not sanitize the water completely. Further, the ionisation process by Aqua Salveo adds some much needed, healthy minerals to the water.

It is also imperitive to use this in water obtained from unknown sources and for water stored in Jerry Cans to both sanitize and prevent any algae growth.

I am absolutely "sold" on the process and the product - Aqua Salveo Details.

Makes me wonder where I can get it in Australia. I have a bit of a lingering smell & rusty taste in my tank water.

The supplier will post or courier to you.

Rust however, is a different problem. You would have to establish the extent of the problem and take decisions on what you find in your tanks. The "treated" water will however be good.

Note: When flushing tanks be sure to "treat" all the water lines overnight as well. After adding the product to the water tanks, run water through all the onboard taps/lines and then close off and leave overnight and fully flush/empty the tanks the following day. This will ensure that all the water lines are "treated" as well.

The recommendation from Lighthouse should be followed, especially as Kevin advises that the water in his boat's tanks have been sitting there for some 4 years. This being the case the tanks should be thoroughly pumped out first, and if the tanks are metal tanks and have inspection plates these to be removed to aid the cleaning process - once the tanks are clean - they should be refilled (at least once) and if using water from a source that has been filtered and subsequently chlorinated , this water it should be allowed to stand for a couple a days before adding the Aqua Salveo in the amount specified for treating the amount of water in the tanks.

I've done a quick search and it seems that this product only comes from South Africa. I am awaiting email on the costs to get it shipped to Australia. Then I'll have to find out if it is allowed into Australia.

Let ya know

Got an email back from cruiserconnections, for 1 ltr which is enough to treat 10000 ltrs is $125 express to Queensland.

Interesting Read folks!

Wonder what ever happened to using bleach in the water tanks. We have been using bleach for the past 25 years and it seems to have worked just fine. You can buy it just about everywhere. Once a year we dose the tanks with a shock treatment, flush a couple of times and carry on. We back flush the watermaker with tank water using filters designed to remove any potential traces of bleach in the tanks.

Just a thought.

Kind regards,

Chuck

Hi Chuck

Do you mean the bleach that is used for taking stains out of clothing? That has a strong taste and odour? That is not made for human consumption, especially over long periods? That corrodes plumbing?

Yes, it works.

Bob

svjacaranda · 10-28-2007, 09:32 PM

HiBob - Yes that type of bleach. We put a tablespoon for every 20 gallons in the tank and leave the cap off the fill. Within an hour the bleach smell and taste evaporates. We use a small onboard filter that removes any other taste and smell. For yearly shock treatment we use 1/2 cup per 35 gallons.

Have not had any trouble with plumbing or hoses being effected. It has been the standard way to treat water for many years on cruising vessels. NOT saying its the only way and found the above related information interesting.

Regards

Chuck

I was wondering the same thing about bleach. I used it for the time I was in Mexico, 93-95. I sailed down Baja, and then over to Puerto Vallarta, and then back home to S.F. Aqua Salveo sounds very interesting although expensive.

We cruised for 5 years - up the East African coast and SE Asia. We HAD to treat the water and bleach was the only option at the time. We could however never get used to the smell or taste of the bleach and was concerned about the effects on our health and turned to purchasing bottled water - an expensive option. I believe that Aqua Salveo is finally the answer we have all looked for, for years. Ionisation makes so much sense.

I did a search on the Net and found that the ancient Greeks used the ionisation principle - they placed coins in their water storage earns to sanitize the water and keep it potable for longer. Interesting.

Silver is an excellent antimicrobial agent. Though I haven't found it lately, West Marine used to sell a filter that used silver as the sanitizing agent. However, I don't believe that badly contaminated water tanks can be adequately decontaminated that way. Chlorine bleach or sodium metabisulphide (the agent used to clean home brew equipment) are far more effective at destroying the heavy contamination in tanks that have sat too long. When we had to clean our tanks due to bad water, we would drain them, heavily chlorinate the water we put into the tanks, run it all through the lines, drain and fill with fresh water, or repeat the treating and flushing if the water coming out wasn't clear. We had inspection ports, so we were able to open up the tanks and get a long stick with a rag tied to it to scrub the walls of the tank as well, though that was not usually necessary since we were living on the boat full time. It's a lot cheaper than treating heavily contaminated water with Aqua Salveo.

It is rare that I liked the taste of any water we had, no matter where it came from. For that reason we had a two-stage water filter installed under the galley sink with a separate filtered water spigot, which water I used for drinking and cooking. The first stage filter removed silt, the second 1 micron paper & charcoal filter removed fine silt, chlorine, other tastes, metals and cysts such as cryptosporidia (which aren't killed by chlorine or most other biocides). see re cryptosporidia: http://www.cdc.gov/ncidod/dpd/parasites/cr...sporidiosis.htm

No matter how heavily I chlorinated the water, the charcoal filter removed all taste, and the multi-filtration removed even the finest silt.

Considering the silver in Aqua Salveo, is there any caution about using it with aluminum water tanks? I would think that it would accelerate galvanic corrosion in aluminum tanks. Anybody know the answer to this?

seaescape · 10-30-2007, 01:49 AM

Hi Got another email from a company in South Africa called Fevertree to supply Aqua Salveo. Alot cheaper than cruiserconnections.

one Litre=R200 and post to Oz R95 thats only $A47.00

JeanneP

"heavily chlorinate the water we put into the tanks"

Is this "Bleach for clothes" or "Chlorine that one would put in a swimming pool."

On the Aqua Salveo I was going to drain the tanks into my bilge (after treatment) then pump it out. My boat is Aluminium. Could this be a problem with respect to JeanneP question on galvanic corrosion.

Thanks

Kevin

Hi Kevin

They have quoted you for 100ml and not 1,000ml (1 liter) - expensive. Fevertree is a healthshop/retailer - Cruising Connections is the wholesaler/distributor.

Which 2 stage filter do you use?

Just a standard household system.

Here's a link to full size photo: http://www.fototime.com/3CB90266AA12713/standard.jpg

The one shown was used to filter the water before it went into our tanks - I'm comparing the new, unused filters to the filter in the housing after just one 75-gallon tank fill in Malaysia. The water in Malaysia, where this picture was taken, was extremely silty and if we didn't filter it before it went into the tanks we had a big job of cleaning the tanks after a couple weeks as the silt settled to the bottom of the tank and more silty water was added before the tanks were completely empty. The second stage was the same filter housing with a one micron filter element and charcoal filter to remove taste and chemical contaminants. I liked the clear filter housing so I could easily see how dirty the filter was. The shortcoming of a clear filter housing, though, is that light will enable alagae to grow in the housing unless it is stored away from light.

The space in the galley was not big enough to mount both filters side-by-side, so prefiltering the water before it reached the tank was a necessity as well as a good idea.

You can buy these most places of the world, though they're probably cheapest in the US. I had a special filtered water faucet at the galley sink so that only drinking and cooking water was filtered, making the filter last longer.

Auzzee · 11-08-2007, 08:38 PM

Hi Jeanne,

How does the pre-filter affect the speed and manner of refilling the tanks? I imagine it would become a relatively slow process. Can water be poured through the filter, or does it require to be forced through, under mains pressure?

Cheers

David.

JeanneP · 11-08-2007, 10:01 PM

David, we've done it both ways. The diameter of the hoses are a bit smaller than dock hoses, so it's not that much slower than going from hose directly into the tanks. But it also works quite well when siphoning from jerry jugs, which was our usual means of getting fresh water to the boat - I don't think that it slows the water flow down much, if at all.
