If anyone can give you guidance, it is Arrow Tank and Engineering:

No instructions were posted on the web site but I'm sure you can call them and get the proper procedure.

If you can tell me what manufacture your looking at, I may be able to help with a PDF version of the manual.
Rockwood, now owned by Ansul, used to have an odd design in what they called their "Diaphragm" tank. This was simply a bladder that went between two halves of a tank with foam on one side and water on the other.
Regardless of the manufacture the filling procedures are basically the same.

I´d appreciate if you could send me a link or a pdf to davidleiva@costarricense.cr
Thanks a lot.

The proportioning system can be tested using foam concentrate or an environmentally friendly alternative. I've not been involved with a test on a bladder tank, but am sure it can be done. If you're looking for someone to help try Vector Fire Technology (610-466-1717). They work nation wide and specialize in foam system testing.

Did you manage to locate a manual? Is your project already installed. If so is there any chance I could see a few pictures? We just got the pump room design back from the engineers and I'm about to statert with the take-offs. To see how someone else has done it would be very helpful.

Thanks, no manual yet.
I tried your link and also failed.
A man from Chemguard told me he´ll send me one, but I´m still waiting. I been given some hints, and technical info on bladder tanks but nothing written. So if you have any particular question maybe I could comment on it.
From a propposal I´ve been suggested I´m couriuos: has anyone seen foam chambers protecting a diesel fuel fixed roof tank with 1% AFFF foam?. Some told me that it is not a problem and others tell that there are no foam chambers that have been "approved, tested or listed" with 1%, and most of all are designed to work with 3%, any comment? I use the quotation marks because I´m not sure of the need or existence of listings of foam chambers for specific foam concentrates and solutions.
RE: Foam bladder tank operation manual
Technically speaking, everything in a fire system is supposed to be listed to work with everything else in the system. However, from a practical stand point most look at this as "parts is parts" and will call it good as long as the equipment has a listing (any listing). I would talk to your 1% liquids mfr. though before mating it with a foam chamber that it has not been tested on. I don't know if there are any increased or decreased agitation/mixing requirements with 1% compared to the traditional concentrates.
The manufacturers of foam equipment don't help much in this regards either. Their listings are always tricky, as some manufacturers list every piece of equipment with every liquid they make (expensive from a testing/listing standpoint), while others selectively list some of their equipment to certain liquids and call the rest good by comparative analysis.

RE: Foam bladder tank operation manual
Our company has all the equipment sized for AFFF3% but a vendor told us why we don´t go to AFFF%1, considering that in general modern 1% foams tend to be more efecctive, this will impact a lot in sizing a bladder tank for example.
I´ve gave glance to technical sheets and in general all manufacturers have the possibility to size the equipments to 1%, but dealing with the concentrate some say that 1% is a modern better foam that work excellent with aspirating and non aspirating devices, and since 1% works fine with non air aspirating devices they should work fine with a foam chamber. Others are more conservative and say that for foam chambers is better to stay with the 3%, but they don´t have a technical reason, they only mention listings that I really don´t know in detail.
I agree with you that listings are tricky in the sense that sometimes they just list what they are ment to list but not necesarily list the real use you are looking for.
RE: Foam bladder tank operation manual
The only true difference that I am aware of is that they reduce your storage quantities and/or tank sizes by 2/3's compared to 3% concentrates.
